China best Zs Factory Price High Precision Oldham Shaft Coupling for Automation Machinery oldham coupling

Product Description

Introduction 

  • Oldham couplings are a 3 piece design comprised of 2 aluminum hubs press fit CHINAMFG a center disk. Torque transmission is accomplished by mating the slots on the center disk to the drive tenons on the hubs. During operation the center disk slides on the tenons of each hub (which are orientated 90 apart) to transmit torque.
  • While the couplings accommodate a small amount of angular and axial misalignment, they are especially useful in applications with parallel misalignment.
  • We offers oldham couplings in set screw or clamp styles with bores ranging from 4mm to 35mm. Inch and metric hubs (set screw, clamp style, keyed, or keyless) are interchangeable and can be combined into a single coupling as long as they have the same outside diameter. Oldham coupling hubs are standard in black anodized aluminum for improved lubricity, increased life, and low inertia. Hubs are also available in stainless steel CHINAMFG request for increased corrosion resistance.

Application

  • Ideal for many light duty industrial and motion control applications, oldham couplings have the ability to protect more expensive machinery components.
  • For example the oldham coupling acts as a torque limiter during overload. When the disk fails, it breaks cleanly and does not allow any transmission of power.
  • Oldham couplings also have the advantage of electrical isolation due to the non-conductive nature of the center disk.
  • This prevents electrical currents from being passed to delicate instruments which can cause inaccurate data readings or damage.

Feature

  • High absorption capacity of radial misaligment
  • They do not produce kinematic errors in transmission
  • Elimination of loads on shaft
  • Mechanical protection against excessive torque
  • Replaceable disc

    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.

    How to Calculate the Required Size and Specifications for an Oldham Coupling

    Calculating the required size and specifications for an Oldham coupling involves considering several key factors. Here’s a step-by-step guide to help you with the calculations:

    1. Identify the Torque Requirements: Determine the maximum torque that the coupling needs to transmit between the two shafts. This can be done by analyzing the torque demands of the application and considering safety factors.
    2. Select the Coupling Material: Based on the operating conditions and the type of machinery, choose a suitable material for the Oldham coupling. Common materials include aluminum, stainless steel, and acetal.
    3. Calculate the Bore Diameter: Measure the diameters of the shafts that the coupling will connect. The bore diameter of the coupling should match the shaft diameters for a proper fit.
    4. Determine the Coupling Size: The coupling’s size is typically specified by its outside diameter and length. Ensure that the selected coupling size fits within the available space in the mechanical system.
    5. Consider Misalignment Compensation: Oldham couplings can accommodate angular misalignment. However, it’s essential to check the coupling’s rated misalignment capability to ensure it meets the application’s requirements.
    6. Check Operating Speed: Verify that the selected coupling can handle the rotational speed (RPM) of the application without exceeding its critical speed.
    7. Factor in Environmental Conditions: If the coupling will be exposed to harsh environmental conditions or corrosive substances, choose a material that can withstand these conditions.

    Once you have gathered all the necessary information and made the calculations, you can select the appropriate Oldham coupling that meets the requirements of your specific application. It’s important to consult with coupling manufacturers or engineering experts to ensure the coupling’s compatibility and reliability in your system.

    Materials Used in Manufacturing Oldham Couplings

    Oldham couplings are commonly made from various materials to suit different application requirements. The choice of material depends on factors such as torque capacity, operating conditions, and environmental considerations. Some of the commonly used materials in manufacturing Oldham couplings include:

    • Aluminum: Aluminum is a popular choice for Oldham couplings due to its lightweight and excellent machinability. It is suitable for low to medium torque applications and offers good corrosion resistance.
    • Stainless Steel: Stainless steel is known for its high strength, corrosion resistance, and durability. Oldham couplings made from stainless steel are ideal for applications requiring higher torque transmission and operating in harsh or corrosive environments.
    • Acetal: Acetal, also known as Delrin, is a thermoplastic material with good mechanical properties. It provides low friction and wear resistance, making it suitable for applications where reduced friction is essential.
    • Nylon: Nylon is another thermoplastic material used in Oldham couplings. It offers good chemical resistance and is often chosen for applications with moderate torque requirements.
    • Carbon Steel: Carbon steel is robust and cost-effective, making it suitable for heavy-duty applications. It has high strength and can handle higher torque loads compared to some other materials.
    • Brass: Brass is a durable metal that offers good corrosion resistance. Oldham couplings made from brass are suitable for certain industrial and marine applications.

    The material selection for an Oldham coupling depends on factors such as the torque to be transmitted, operating speed, environmental conditions, and budget constraints. Manufacturers often offer a range of material options to meet the diverse needs of different industries and applications.
