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

    Can an Oldham Coupling Reduce Vibration and Backlash in Mechanical Systems?

    Yes, an Oldham coupling can help reduce vibration and minimize backlash in mechanical systems, making it a popular choice for applications that require precise and smooth power transmission.

    Vibration Reduction: Oldham couplings are designed with a three-piece construction, comprising two hubs and a center disc. The center disc, also known as the spacer, is made of a flexible material such as acetal or nylon. When torque is transmitted through the coupling, the center disc flexes, absorbing any misalignment between the shafts. This flexing action helps dampen vibration and reduces resonance in the system, leading to smoother operation and less mechanical stress on connected components.

    Backlash Minimization: Backlash is the amount of play or free movement between the mating parts of a mechanical system. In traditional couplings like gear couplings, there can be significant backlash due to the nature of the gear teeth. However, Oldham couplings have a unique design that allows them to transmit torque with minimal backlash. The center disc provides a small amount of clearance between the hubs, enabling smooth rotation without backlash. This characteristic is especially beneficial in applications that require precise motion control, such as robotics and CNC machines.

    Overall, the flexible and backlash-free nature of Oldham couplings makes them well-suited for applications where vibration reduction and precise motion control are essential. By reducing vibration and backlash, Oldham couplings contribute to the overall efficiency, accuracy, and reliability of the mechanical system they are employed in.

    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.

    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 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.

      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.

        2. Proper Installation: Ensure the coupling is installed correctly and securely to prevent any chances of coupling failure or disengagement during high-speed operation.

        3. Balancing: Balance the coupling components accurately to minimize vibration and prevent excessive wear, which can be more pronounced at high speeds.

        4. Regular Inspections: Implement a regular inspection and maintenance schedule to identify any signs of wear, misalignment, or damage that may occur due to high-speed operation.

        5. Lubrication: Use appropriate lubrication to reduce friction and heat generation, which is crucial in high-speed applications.

        6. Temperature Consideration: Monitor the temperature of the coupling during operation as high speeds can result in increased heat generation.

        7. Avoid Overloading: Do not exceed the recommended torque and speed limits specified by the manufacturer to avoid overloading the coupling.

        8. Coupling Guards: Consider using coupling guards or covers to protect personnel from rotating or moving coupling components in high-speed systems.

        Differences Between Oldham Couplings and Other Types of Flexible Couplings

        Oldham couplings are a type of flexible coupling used in mechanical systems to transmit torque between two shafts. Here are some key differences between Oldham couplings and other types of flexible couplings:

        • Mechanism of Torque Transmission: Oldham couplings use a sliding motion between the center disc and the hubs to transmit torque. The center disc has slots that engage with pins on the hubs, allowing for torque transmission while accommodating misalignment. In contrast, other flexible couplings, such as jaw couplings or beam couplings, typically use elastic materials or flexible elements like rubber or springs to transmit torque.
        • Misalignment Compensation: Oldham couplings are specifically designed to handle angular misalignment between shafts. They can accommodate parallel misalignment to a limited extent but are not well-suited for axial misalignment. Other flexible couplings like beam couplings or bellows couplings may offer more comprehensive misalignment compensation, including axial misalignment.
        • Backlash: Oldham couplings have a small amount of backlash due to the clearance between the center disc and the hubs. This backlash can be beneficial in some applications to reduce shock loads and vibrations. However, other flexible couplings like beam couplings or jaw couplings may have minimal or zero backlash.
        • Construction and Materials: Oldham couplings are typically made of materials like aluminum for the hubs and center disc, and acetal or other plastics for the center disc’s sliding parts. Other flexible couplings come in various materials, including aluminum, stainless steel, elastomers, and composite materials, depending on the application’s requirements.
        • Operating Speed: Oldham couplings are suitable for moderate to high rotational speeds, but their speed limitations depend on the material and design. Some other flexible couplings, such as bellows couplings, can handle even higher speeds due to their construction.
        • Applications: Oldham couplings are commonly used in applications that require moderate torque transmission and angular misalignment compensation, such as pumps, packaging machines, and automation equipment. Other flexible couplings are used in a wide range of applications, including motion control systems, robotics, aerospace, and automotive industries, where specific coupling characteristics are needed.

        Choosing the right flexible coupling depends on the specific requirements of the application, including torque, misalignment, speed, space constraints, and environmental conditions. Engineers and designers should carefully consider these factors to select the most appropriate coupling for their mechanical system.

        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.
