Product Description

Custom CNC Turning Machining  Spline Shaft Couplings Steering Shaft Coupler Oldham Coupling
 

Product Description

 

Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used
as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.

Couplings can be divided into rigid couplings and flexible couplings. Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.

Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. 

Our leading mainly including universal couplings, drum gear couplings, elastic couplings etc.

What are the Potential Limitations or Drawbacks of Using an Oldham Coupling?

While Oldham couplings offer numerous advantages, they also have some limitations and drawbacks that should be considered when selecting a coupling for a specific application:

1. Limited Misalignment Capacity: Oldham couplings can only accommodate small amounts of angular and axial misalignment between the shafts. They are not suitable for applications with high levels of misalignment as excessive misalignment can lead to premature wear and failure of the center disc.

2. Speed Limitations: Oldham couplings are generally not recommended for high-speed applications. The flexible center disc has a maximum speed limit, and exceeding this limit can cause the disc to fatigue and fail over time.

3. Temperature Sensitivity: The performance of Oldham couplings can be affected by temperature fluctuations. Extreme temperatures can impact the flexibility and integrity of the center disc material, leading to reduced coupling performance.

4. Backlash in High-Precision Systems: While Oldham couplings minimize backlash compared to some other couplings, they may still have some inherent clearance between the hubs and the center disc, leading to a slight amount of backlash. In ultra-high-precision systems, this slight backlash may be a concern.

5. Material Compatibility: The material used for the center disc must be chosen carefully to ensure compatibility with the specific application’s environment and the media being conveyed. Some aggressive chemicals or harsh environments may degrade the material over time.

6. Maintenance: Oldham couplings require periodic inspection and maintenance to ensure proper functioning. The center disc may wear out over time and need replacement, especially in applications with high torque or frequent start-stop cycles.

Despite these limitations, Oldham couplings remain a popular choice in many applications due to their vibration reduction, backlash minimization, and moderate misalignment compensation capabilities. However, it is essential to carefully assess the specific requirements of the application and consider the potential drawbacks before selecting an Oldham coupling.

  • Vibration and Noise Damping: The sliding action of the middle block in the coupling helps to isolate the shafts from each other, reducing vibrations and noise during operation. This feature is beneficial in applications where vibration dampening is critical to equipment performance and longevity.
  • High Torque Transmission: Oldham couplings can handle relatively high torque transmission, making them suitable for applications with moderate to high torque requirements.
  • Low Maintenance: Due to its design, the Oldham coupling experiences minimal wear during operation, leading to lower maintenance requirements and longer service life.
  • Easy Installation: Oldham couplings are relatively easy to install and remove, simplifying maintenance and replacement procedures.
  • Electrically Insulating: Some Oldham couplings are available with non-conductive materials, providing electrical isolation between shafts, which is essential in certain applications.
  • Cost-Effective: Compared to other high-performance couplings, Oldham couplings are often more cost-effective, providing reliable performance without breaking the budget.

How to Identify Signs of Wear or Damage in an Oldham Coupling?

Regular inspection of Oldham couplings is essential to ensure their proper functioning and prevent unexpected failures. Here are some signs of wear or damage to look for during the inspection:

1. Visible Cracks or Deformation: Check the center disc and the hubs for any visible cracks, tears, or deformation. These can be indicators of excessive stress or misalignment.

2. Abnormal Vibrations: Excessive vibrations during operation may suggest that the coupling is not functioning correctly. It could be due to wear in the center disc or improper installation.

3. Unusual Noise: Grinding, clicking, or banging noises during equipment operation may indicate that the Oldham coupling is experiencing excessive backlash or misalignment.

4. Increased Backlash: If there is noticeable play or free movement between the coupling components, it may be a sign of wear in the center disc or worn hubs.

5. Reduced Performance: A decrease in the performance of the machinery or unexpected issues with power transmission could be indicative of coupling problems.

6. Abnormal Heating: If the coupling becomes unusually hot during operation, it may suggest friction or misalignment issues.

7. Excessive Wear on Center Disc: Inspect the center disc for signs of wear, such as grooves, uneven surfaces, or material loss. This may occur over time due to the repeated flexing of the disc.

8. Lubrication Issues: Improper or inadequate lubrication can lead to increased friction and wear in the coupling components.

If any of these signs are observed during the inspection, it is essential to address the issue promptly. Depending on the severity of the wear or damage, the Oldham coupling may require replacement or repair. Regular maintenance and proper lubrication can help extend the life of the coupling and prevent unexpected failures, ensuring smooth and reliable operation in the machinery or equipment.

Can an Oldham Coupling be Used in Precision Motion Control Applications?

Yes, an Oldham coupling can be used in precision motion control applications. Oldham couplings are known for their ability to provide constant velocity transmission while accommodating misalignment. These couplings offer low backlash and minimal hysteresis, making them suitable for precision motion control systems.

Precision motion control applications require accurate and repeatable motion, which can be achieved by using an Oldham coupling. The coupling’s design allows it to handle angular misalignment without introducing significant axial or radial forces. This feature helps maintain the accuracy and integrity of the motion control system.

Oldham couplings are often used in applications such as robotics, CNC machines, optical equipment, and other systems where precise positioning and smooth motion are essential. Their ability to reduce vibration and minimize backlash is particularly beneficial in these applications, as it enhances the system’s overall performance and accuracy.

When selecting an Oldham coupling for precision motion control, it is essential to consider factors such as the required torque capacity, speed, and shaft sizes. Additionally, regular maintenance and proper alignment are crucial to ensure the coupling’s optimal performance in precision applications.

How an Oldham Coupling Accommodates Misalignment Between Shafts

An Oldham coupling accommodates misalignment between shafts through its unique design, which consists of three main components:

  1. Two Hubs: Each hub is attached to the shaft of the connected equipment. The hubs have a series of slots around their circumference.
  2. Middle Block: The middle block fits between the two hubs and has perpendicular slots on its inner diameter. It connects the two hubs while allowing relative movement between them.

When the shafts experience angular or axial misalignment, the middle block slides within the slots of both hubs. The perpendicular slots on the middle block engage with the slots on the hubs, creating a parallelogram linkage.

This parallelogram linkage allows the Oldham coupling to compensate for angular misalignment by enabling the hubs to rotate independently about their own axes. The sliding action of the middle block accommodates axial misalignment by allowing the hubs to move slightly closer or farther apart.

The use of sliding contact instead of direct physical contact between the hubs minimizes friction, backlash, and wear, making the Oldham coupling an efficient and reliable method for transmitting torque while accommodating misalignment.

Overall, the Oldham coupling’s ability to handle both angular and axial misalignment ensures smooth and precise torque transmission between shafts, reducing stress on connected equipment and extending the lifespan of mechanical components.

What are the Maintenance Requirements for Oldham Couplings to Ensure Their Longevity?

Maintaining Oldham couplings is essential to ensure their longevity and optimal performance. Proper maintenance practices can prevent premature wear and damage, reducing the risk of unexpected failures and downtime. Here are some maintenance requirements to consider for Oldham couplings:

  • Regular Inspection: Perform regular visual inspections of the coupling to check for signs of wear, misalignment, or damage. Look for cracks, corrosion, or any unusual behavior during operation.
  • Lubrication: Oldham couplings may require periodic lubrication to reduce friction between moving parts and prevent excessive wear. Check the manufacturer’s guidelines for the appropriate lubrication schedule and type of lubricant to use.
  • Alignment: Proper alignment is crucial for Oldham couplings to function correctly. Ensure that the shafts and hubs are correctly aligned to avoid additional stress on the coupling components.
  • Torque Check: Periodically check the coupling’s torque to verify that it is within the recommended operating range. Over-torqueing or under-torqueing can lead to coupling failure.
  • Environmental Protection: In harsh environments or applications exposed to contaminants, consider using protective covers or enclosures to shield the coupling from debris, dirt, and moisture.
  • Replacement of Worn Parts: If any component of the Oldham coupling shows signs of wear or damage, promptly replace it with a new one from the manufacturer.
  • Proper Handling: During installation or maintenance, handle the coupling components with care to avoid any accidental damage.

It is crucial to follow the manufacturer’s maintenance guidelines and recommendations specific to the Oldham coupling model being used. Proper maintenance practices will not only extend the coupling’s lifespan but also contribute to the overall reliability and efficiency of the mechanical system it is part of.

Transmission of Torque in Oldham Couplings

An Oldham coupling is designed to transmit torque between two shafts that are misaligned but parallel to each other. It consists of three components: two hubs (also known as drive hubs) and a center disc. The hubs are connected to their respective shafts, while the center disc sits between them.

The center disc of the Oldham coupling is characterized by slots or keyways on its opposite sides, which engage with the hubs. The slots allow the center disc to slide or float within the hubs while maintaining a constant angular velocity between the shafts.

When torque is applied to the drive hub on one side, it induces a rotational force on the center disc. This rotational force is then transferred to the other drive hub, which results in torque transmission to the second shaft. The center disc acts as an intermediary between the two hubs, compensating for any axial or radial misalignment between the shafts.

Regarding the question of different shaft diameters, the Oldham coupling can accommodate shafts with different diameters as long as the hub design allows for a secure connection. The keyways or slots in the center disc and hubs should be compatible with the shaft dimensions to ensure proper torque transmission and to prevent slippage or damage.

It is essential to select the appropriate size and design of the Oldham coupling to match the shaft diameters and to ensure reliable torque transmission while accommodating any misalignment between the shafts.

Types of Couplings

A coupling is a device that connects two shafts together. It transmits power from one end to another and is used for joining rotating equipment. A coupling is flexible and can accommodate a certain amount of end movement and misalignment. This allows for more flexibility in applications. Various types of couplings are available, and each one serves a specific purpose.

Shaft couplings

There are many types of shaft couplings, and they are used in a wide range of applications. The type you need depends on the torque, speed, and horsepower you need, as well as the size of the shaft and its spatial limitations. You may also need to consider whether the coupling will accommodate misalignment.
Some shaft couplings are flexible, while others are rigid. Flexible couplings can accommodate up to two degrees of misalignment. They are available in different materials, including aluminum, stainless steel, and titanium. They can also be known by different names, depending on the industry. Some couplings can also be used in a single or multiple-shaft application.
The first type of shaft coupling is a rigid coupling, which consists of two parts that fit together tightly around the shafts. These couplings are designed to have more flexibility than sleeved models, and they can be used on fixed shafts as well. The flanged coupling, on the other hand, is designed for heavy loads and is made of two perpendicular flanges. The flanges are large enough to accommodate screws and are generally used with heavy-duty applications.
CZPT shaft couplings are a great choice if you’re looking for a shaft coupling that delivers high performance, durability, and low cost. These metal disc-style couplings provide low backlash and high torsional stiffness. Their high misalignment tolerance reduces reaction loads on connected components, which makes them ideal for high-speed precision applications. Available in single and double-disc models, they have torque ratings of up to 2,200 in-lbs. (250N) and are available in fourteen sizes.
When using shaft couplings, it is important to choose the right type for your application. Backlash can cause a shaft coupling to break or become unusable. In order to prevent this from happening, you should replace worn or loose parts, and ensure that the hub and key are evenly positioned with the shaft. If you’re using a shaft coupling in a motion-control system, it is important to keep the torque level consistent.

Flexible couplings

Flexible couplings are a type of coupling used to connect two shafts. They are made of rubber or plastic and allow for axial movement of the connected equipment. They do not require lubrication and are resistant to fatigue failure. Flexible couplings are useful for a number of applications. A common type of flexible coupling is the gear coupling, which has gear teeth inside its sleeve. Another type of flexible coupling is the metallic membrane coupling. A metallic membrane coupling is flexible due to flexing metallic discs.
One major disadvantage of flexible couplings is their inability to fit certain types of pipe. This is because most couplings need to be stretched to fit the pipe. This problem is often the result of a change in pipe technology. Traditionally, drain and soil pipe is made of ductile iron or cast iron. Today, most pipes are made of PVC, which has a larger outside diameter than either cast or ductile iron. Because of these changes in pipe technology, many coupling manufacturers have not updated their mold sizing.
Flexible couplings can be either metallic, elastomeric, or a combination of the three. While there are some common characteristics of each type, you should always consider the tradeoffs of each type before choosing one. Generally, the most important considerations when selecting a flexible coupling are torque, misalignment, and ease of assembly and maintenance.
Flexible couplings are used in a wide range of industries. They are useful for connecting two pipes to ensure torque transfer. Although the types available are different, these are the most adaptable couplings in the market. They can withstand movement, vibration, and bending without causing any damage to the piping.

Clutch couplings

A clutch coupling connects two rotating shafts by friction. The clutch engages power when the engine is running, disengaging power when the brake is applied. Clutch couplings are used in applications where the speed of a machine is variable or where continuous service is required. The clutch can transmit power, torque, and axial force.
Clutch couplings come in a variety of styles and configurations. Some couplings are flexible, while others are rigid. Flexible couplings are available in a variety of materials, including stainless steel and aluminum. Some couplings also have a non-backlash design, which helps compensate for misalignment.
Clutch couplings may be synchronous or asynchronous. Synchronous couplings engage and disengage automatically when the driven machine exceeds its output speed. These couplings are synchronized by a synchronizing mechanism. When the output speed is exceeded, the synchronizing mechanism initiates the engagement process. The synchronizing mechanism does not engage or disengage when the output speed drops.
High speed clutches are available from a variety of manufacturers. Some manufacturers offer OEM assembly, repair services, and third-party logistics. These manufacturers serve the automotive, chemical, food, and wood industries, as well as the oilfield and material handling industries. Custom clutches can be manufactured for specific applications and can be fitted with additional features, such as precision machined teeth or keyway slots and grooves.
Couplings are available in PCE, C/T, and metric bores. Typically, the size of the input and output shafts will determine which type of coupling is needed. In addition, clutches may be configured for intermediate or high speeds, depending on the required torque.

Clamped couplings

Clamped couplings are commonly used in a variety of industries. They can be used in medical equipment, dental equipment, military equipment, laboratory equipment, and in precision industrial controls. They are available in a wide variety of sizes and keyways. This type of coupling offers a number of advantages, including ease of installation and quick and easy replacement.
A clamp coupling connects two parts by compressing them together. The clamping elements can be formed in a variety of ways, but they all have a gap between their surfaces. This friction squeezes the two parts together, much like pulling two rubber gloves apart. This type of coupling is also useful for joining two hoses or piping units.
Clamped couplings are designed with a single or double clamping shaft. The clamping parts are mounted in two halves and are held together by eight socket head cap screws. They offer high torque capacity and require little installation space. Their high rigidity ensures good positioning accuracy, making them ideal for dynamic drives. In addition, they are wear-free and offer simple radial assembly.
The invention relates to a method and system for clamping pipes to a tank vessel. This invention also relates to a method of loading and unloading tank vessels. The method can be used in oil production platforms and other platforms. A single point mooring method is also used in oil production platforms.
Clamped couplings can also be flexible. They can join two shafts together while allowing a small amount of end movement and misalignment. These couplings may also be used in the assembly of motors and gearboxes.
gearbox

CZPT’s coupling

CZPT couplings are designed to be flexible, allowing them to accommodate misaligned shafts and transmit torque in either direction. They are made with three discs, two hubs, and a center that are arranged with grooves and fins. These features allow for two degrees of freedom during assembly, and can accommodate misalignment of up to 5% of the shaft diameter.
CZPT couplings have many uses. For example, they can be used to join two parallel coaxial rotating shafts. Their ability to transmit torque at the same rotation mechanism and speed makes them ideal for applications where electrical currents may be a problem. Because the couplings are not made of metal, they are electrically isolated. Designers should test their couplings during the prototype stage to ensure they are working properly.
The CZPT coupling consists of two hubs with one slot on each. An intermediate disk is located between the two hubs. The discs are used to reduce or prevent wear on other machine parts. CZPT couplings are inexpensive and easy to replace. They also have electrical insulation, which makes them easy to repair or replace.
CZPT couplings are a popular choice for stepper motor-driven positioning stages. The plastic center disc offers electrical isolation and absorbs shocks from frequent start/stops. These couplings are available in through-hub and blind-bore styles and can be installed in many applications.
CZPT couplings also allow for small degrees of shaft misalignment. This allows them to function in systems where shaft access is limited. They are easily removed without tools.

Programming With Couplings

A coupling is a mechanical device that connects two shafts together and transmits power. Its purpose is to join rotating equipment and allows some degree of end-movement or misalignment. There are many different types of couplings. It’s important to choose the right one for your application.

Mechanical connection between two shafts

There are many ways to achieve mechanical connection between two shafts, including the use of a coupling. One common type is the beam coupling, which is also known as a helical coupling. It is used for transmission of torque between two shafts. This type of connection accommodates axial, parallel and angular misalignments.
The hubs and shafts of a worm gear are connected together by a coupling. This mechanical connection allows one shaft to turn another without causing a mechanical failure. This type of coupling is made from sliding or rubbing parts to transfer torque. However, the coupling is not designed to withstand jerks, so it isn’t suitable for high-speed applications.
The use of a coupling is common in machinery and equipment. It helps transmit power from one drive shaft to the other, while adding mechanical flexibility. It is also useful for reducing the impact and vibration caused by misalignment. It also protects the drive shaft components from wear and tear.
A double-hook coupling can be used to provide a uniform angular velocity at the driven shaft. Another example is a double-jointed coupling. A double-jointed coupling can be used to connect shafts that are not directly intersecting. The double-jointed yoke can be used for the same purpose.
A shaft coupling is a device that maintains a strong mechanical connection between two shafts. It transfers motion from one shaft to another, at all loads and misalignments. Unlike a conventional linkage, a shaft coupling isn’t designed to allow relative motion between the two shafts. Couplings often serve several purposes in a machine, but their primary use is torque and power transmission.

Functions that control the flow of another function

One of the simplest programming constructs is a function that controls the flow of another function. A function can take an argument and return a different value, but it must be ready to return before it can pass that value to another function. To do this, you can use the goto statement and the if statement. Another way to control flow is to use a conditional statement.
gearbox

Criteria for selecting a coupling

There are several important factors to consider when choosing the right coupling. One of the most important factors is coupling stiffness, which depends on the material used and the shape. The stiffness of a coupling determines its ability to resist elastic deformation. A stiff coupling is desirable for certain types of applications, but it’s undesirable for others. Stiffness can reduce the performance of a system if there’s too much inertia. To avoid this, ensure that the coupling you choose is within the recommended limits.
The size of a coupling is also important. Different coupling types can accommodate different shaft sizes and shapes. Some couplings have special features, such as braking and shear pin protection. When choosing a coupling, you should also consider the type of driven equipment. If you need to connect a high-torque motor, for example, you’ll want to choose a gear coupling. Likewise, a high-speed machine may require a disc coupling.
Another factor to consider when selecting a coupling is the torque rating. Despite its importance, it’s often underestimated. The torque rating is defined as the torque of the coupling divided by its OD. In some cases, torque may fluctuate during a cycle, requiring a coupling with a higher torque rating.
Torsionally flexible couplings are also important to consider. Their design should be able to withstand the torque required during operation, as well as the required speed. The coupling should also have a high degree of torsional stiffness, as well as damping. Furthermore, a damping coupling can reduce the energy wasted through vibration.
The sizing of a coupling is also determined by the torque. Many engineers use torque to select the correct coupling size, but they also take into consideration torsional flexibility and torsional stiffness. For example, a shaft may be able to handle large torque without damaging the coupling, while a disk may be unable to handle large amounts of torque.
Besides torque, another important consideration in coupling selection is the cost. While a coupling may be cheaper, it may be less reliable or easier to maintain. Couplings that are difficult to service may not last as long. They may also require frequent maintenance. If that’s the case, consider purchasing a coupling with a low service factor.
There are many different types of couplings. Some require additional lubrication throughout their lifetime, while others are 100% lubrication-free. An example of a 100% lubrication-free coupling is the RBI flexible coupling from CZPT. This type of coupling can significantly reduce your total cost of ownership.
In addition to the above-mentioned benefits, elastomeric couplings are low-cost and need little maintenance. While they are often cheaper than metallic couplings, they also have excellent shock absorption and vibration dampening properties. However, they are susceptible to high temperatures. Also, they are difficult to balance as an assembly, and have limited overload torque capacity.

Understanding the Different Types of Couplings

A coupling is a device that joins two rotating shafts together. It transmits power from one to the other and is designed to allow some amount of end-movement and misalignment. It is a simple mechanism that is extremely common in many industries. Learn more about couplings in this article.

Flexible coupling

When choosing the correct flexible coupling for your application, there are several factors to consider. One of the most important factors is backlash, which is the amount of rotational play introduced by moving parts. Other factors to consider include lubrication and accessibility for maintenance. Choosing the right flexible coupling can be challenging, but it is possible to find the right fit for your specific application.
A flexible coupling is an excellent choice for applications that require high alignment accuracy, which is essential for reliable system performance. These couplings can compensate for angular and parallel misalignment, ensuring proper positioning between the driving and driven shafts. In addition, flexible couplings are more affordable than most traditional couplings.
The most common flexible coupling is the elastomeric type, which uses a resilient material to transmit torque. These couplings can be made of plastic or rubber. In either case, they can be relatively lightweight compared to other types of couplings. Elastomeric couplings can also be used for high-speed applications.
Another important factor to consider when selecting the best Flexible Coupling is the pipe you’re connecting. Some couplings are easier to install than others, and some even have tapered edges to make them slide easily on the pipe. Regardless of the choice you make, it’s crucial to remember that proper installation is critical for reliability and safety.

CZPT coupling

An CZPT coupling is a flexible, mechanical coupling that features a high degree of angular misalignment and eccentricity. They are available in different lengths, with MOL being the longest. They are ideal for applications that involve high parallel misalignment, limited assembly access, electrical insulation, and other conditions.
CZPT couplings are a versatile type of coupling, and they are often used to connect parallel shafts. They work by transmitting torque from one to the other using the same speed and rotation mechanism. They are available in various materials, including aluminum, brass, and polymers. In addition, they can work under high temperatures.
One of the main benefits of using an CZPT coupling is the fact that it does not require the use of a gearbox. These couplings are flexible, and their design allows them to cope with misalignment problems that may occur in power transmission applications. They are also able to absorb shock.
Another advantage of CZPT couplings is that they are suitable for systems with low-to-medium amounts of shaft misalignment. Because their friction is limited to the surface of the hubs, they are able to accommodate low bearing loads. CZPT couplings can also be used in systems with limited shaft access, since the disks are easily removed.

Clamped coupling

Clamped couplings are designed to provide a high-strength connection between two objects. A standard coupling has two parts: a nipple and a clamp sleeve. Each part is designed in such a way as to cooperate with each other. The sleeve and clamp are made of rubber. A reinforcing braid is often used to protect the exposed steel braid from rusting.
PIC Design provides a wide variety of standard clamping couplings for many different industries. These include medical, dental, military, laboratory, and precision industrial control equipment. They have a simple design that makes them ideal for these applications. Clamped couplings are also available for custom manufacturing. These couplings are available in metric, inch, and Metric.
The most common type of clamp coupling is a hose clamp. This type of coupling is used to connect two hoses or piping units. It consists of two conical binding sleeves that fit into the ends of the two parts. The coupling is then tightened with a screwdriver. It’s a versatile coupling because it allows two piping units or hoses to be joined together.
Another type of clamp coupling is the two-piece clamp coupling. The two-piece design allows for a quick and easy installation. Unlike other types of couplings, the clamp coupling is not necessary to remove the bearings before installing it. Its keyway is designed with shims in place so that it fits over the shaft. These couplings are available in different sizes, and they are made of steel or dutile iron.

Helicoidal coupling

Helicoidal coupling is a form of nonlinear coupling between two molecules. It occurs when the molecules in a double helix are subjected to oscillations. These oscillations can occur either in the right or left-handed direction. These oscillations are called solitons. Helicoidal coupling can provide quantitative or qualitative support to a structure, such as an electron.

Flexible beam coupling

The Flexible beam coupling is one of the most popular types of couplings in the industry. It is comprised of two sets of parallel coils separated by a solid member, and it offers a wide range of torsional stiffness. These couplings are made of aluminum alloy or stainless steel. They offer excellent flexibility and are less expensive than many other types of couplings. They also require zero maintenance and can tolerate shaft misalignment.
Beam couplings are categorized into two types: helical and axial. The former is characterized by a high degree of flexibility, while the latter is used to compensate for higher misalignment. Both types are suitable for small torque applications and are available in a wide range of shaft sizes.
Flexible beam couplings are available in metric and US sizes, and feature a variety of options. They feature stainless steel or aluminum materials and are highly durable and corrosion-resistant. They also offer high torque capacities and excellent fatigue resistance. Flexible beam couplings are available with a wide range of options to meet your unique application needs.
