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.

Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CZPT requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.

Dynamic balance tester, high-speed intelligent carbon and sulfur analyzer, Blochon optical hardness tester, Leeb hardness tester, magnetic yoke flaw detector etc.
  
It is widely used in metallurgical steel rolling, wind power, hydropower, mining, engineering machinery, petrochemical, lifting, paper making, rubber, rail transit, shipbuilding and marine engineering and other industries.

How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

Different Sizes and Configurations of Oldham Couplings

Yes, Oldham couplings are available in various sizes and configurations to suit different applications and requirements. The sizes and configurations can vary based on factors such as torque capacity, shaft diameter, and overall dimensions. Some common variations include:

1. Shaft Diameters: Oldham couplings come in a range of shaft diameter options to accommodate different motor and shaft sizes. They can be found in standard metric and imperial sizes, making them compatible with various equipment and machinery.

2. Torque Capacity: Oldham couplings are designed to handle different torque capacities. The torque capacity of a coupling depends on its size, materials used, and overall construction. High-performance couplings can transmit higher torques, while smaller couplings may be suitable for lighter applications.

3. Coupling Length: The length of the coupling can vary, and some designs allow for compact installations in confined spaces, while others may have longer lengths for specific applications.

4. Materials: Oldham couplings are manufactured using various materials such as aluminum, stainless steel, and composite materials. The choice of material depends on factors like the operating environment, chemical resistance, and desired performance characteristics.

5. Spacer Type: Oldham couplings may have different spacer designs, including straight-spacer and step-spacer configurations. The choice of spacer type can affect the overall stiffness and misalignment capabilities of the coupling.

6. Hub Style: Oldham couplings come with different hub styles, such as set screw, clamp, or compression-style hubs, to accommodate various shaft attachment methods and ease of installation.

7. Backlash: Couplings may have different backlash characteristics, allowing for minimal angular play between the hubs to reduce vibration and shock loads.

Manufacturers of Oldham couplings typically provide detailed specifications and product catalogs that outline the available sizes and configurations. It’s essential to select the right coupling size and configuration that matches the requirements of the specific application to ensure optimal performance and longevity.

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.
