China manufacturer Zs Factory Price High Precision Oldham Flexible Couplings 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

    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.
