Product Description
OEM Precision CNC Machining Clamping Type Flexible Disc Coupling Jaw Coupling Oldham Coupling for Metallurgy/Mining/Power/Pump
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.

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 CHINAMFG 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.

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.

How to Identify Signs of Wear or Damage in an Oldham Coupling?
Regular inspection of Oldham couplings is essential to ensure their proper functioning and prevent unexpected failures. Here are some signs of wear or damage to look for during the inspection:
1. Visible Cracks or Deformation: Check the center disc and the hubs for any visible cracks, tears, or deformation. These can be indicators of excessive stress or misalignment.
2. Abnormal Vibrations: Excessive vibrations during operation may suggest that the coupling is not functioning correctly. It could be due to wear in the center disc or improper installation.
3. Unusual Noise: Grinding, clicking, or banging noises during equipment operation may indicate that the Oldham coupling is experiencing excessive backlash or misalignment.
4. Increased Backlash: If there is noticeable play or free movement between the coupling components, it may be a sign of wear in the center disc or worn hubs.
5. Reduced Performance: A decrease in the performance of the machinery or unexpected issues with power transmission could be indicative of coupling problems.
6. Abnormal Heating: If the coupling becomes unusually hot during operation, it may suggest friction or misalignment issues.
7. Excessive Wear on Center Disc: Inspect the center disc for signs of wear, such as grooves, uneven surfaces, or material loss. This may occur over time due to the repeated flexing of the disc.
8. Lubrication Issues: Improper or inadequate lubrication can lead to increased friction and wear in the coupling components.
If any of these signs are observed during the inspection, it is essential to address the issue promptly. Depending on the severity of the wear or damage, the Oldham coupling may require replacement or repair. Regular maintenance and proper lubrication can help extend the life of the coupling and prevent unexpected failures, ensuring smooth and reliable operation in the machinery or equipment.
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.
Advantages of Using an Oldham Coupling Compared to Other Types of Couplings
An Oldham coupling offers several advantages over other types of couplings, making it a preferred choice in certain applications:
- Misalignment Compensation: The Oldham coupling can handle both angular and axial misalignments between shafts. It allows for up to a few degrees of misalignment while transmitting torque smoothly, reducing the risk of premature wear and failure caused by misalignment.
- No Backlash: Unlike some other flexible couplings, the Oldham coupling has minimal backlash. This means there is little to no play or clearance between the coupling components during rotation, ensuring precise torque transmission and positioning in high-precision applications.
- Vibration and Noise Damping: The sliding action of the middle block in the coupling helps to isolate the shafts from each other, reducing vibrations and noise during operation. This feature is beneficial in applications where vibration dampening is critical to equipment performance and longevity.
- High Torque Transmission: Oldham couplings can handle relatively high torque transmission, making them suitable for applications with moderate to high torque requirements.
- Low Maintenance: Due to its design, the Oldham coupling experiences minimal wear during operation, leading to lower maintenance requirements and longer service life.
- Easy Installation: Oldham couplings are relatively easy to install and remove, simplifying maintenance and replacement procedures.
- Electrically Insulating: Some Oldham couplings are available with non-conductive materials, providing electrical isolation between shafts, which is essential in certain applications.
- Cost-Effective: Compared to other high-performance couplings, Oldham couplings are often more cost-effective, providing reliable performance without breaking the budget.
Overall, the Oldham coupling is an excellent choice in applications where misalignment compensation, precision torque transmission, vibration dampening, and low maintenance are critical factors for successful operation. Its unique design and features make it suitable for various industrial and automation systems, contributing to smoother and more efficient mechanical power transmission.
