China Good quality 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 CZPT 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 CZPT 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.

    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.

    What is an Oldham Coupling and How Does It Function in Mechanical Systems?

    An Oldham coupling is a type of flexible coupling used in mechanical systems to transmit torque between two shafts that are misaligned. It consists of three main components: two hubs or discs and a middle block. The two hubs are connected to the respective shafts, and the middle block sits in between them.

    The key feature of the Oldham coupling is the middle block, which has slots on its opposite faces and is connected to the hubs using pins or keys. The slots in the middle block are oriented perpendicular to each other, allowing the middle block to move in a plane perpendicular to the axis of the shafts.

    When torque is applied to one shaft, it is transmitted to the middle block of the coupling. Due to the slots, the middle block can slide laterally as the shafts rotate, accommodating both angular and axial misalignments between the shafts. This sliding action helps to reduce the reaction forces and wear that would otherwise occur in rigid couplings when misalignment is present.

    Oldham couplings are known for their ability to provide constant velocity transmission even when misalignment exists. They do not have any backlash, which means there is minimal play between the coupling components during rotation. This feature makes them suitable for precision applications where accurate torque transmission and positioning are required.

    One of the main advantages of the Oldham coupling is that it effectively isolates the connected shafts from each other, which can help in reducing vibrations and noise. Additionally, it can compensate for parallel misalignment between the shafts, making it ideal for applications where parallel shafts need to be connected while allowing some degree of misalignment.

    Oldham couplings are commonly used in various industrial machinery and automation systems, including CNC machines, robotics, printing presses, and conveyor systems. They are particularly useful in applications where precise torque transmission, misalignment compensation, and low maintenance are essential.
