6.Hole can be self-processing,easy facilitate.
7.For step motor,screw, machine positioning system.
The SL cross slide coupling is slid in the corresponding radial grooves of the large end faces
of the half couplings on both sides.
The main feature of the slider coupling is that it allows the 2 shafts to have a large radial
displacement, and allows for small angular displacement and axial displacement. Due to the
centrifugal force generated by the eccentric motion of the slider, it is not suitable to use this
coupling. High-speed movement, the coupling torque of the coupling is 120-63000N.m, the
speed is 250-70r/min.

Advantages:
Protects driven component by serving as a mechanical “fuse” – an inexpensive replaceable plastic
midsection shears under excess load.
Protects support bearings by exerting consistently low reactive forces, even under large misalignments.
Homokinetic transmission – driving and driven shafts rotate at exactly the same speed at all times.
Zero backlash and high torsional stiffness.
Accommodates large radial misalignment in a short length.
Easy installation in blind or difficult installations when through-bores are used.
Economically priced compared to other couplings with similar performance characteristics.

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:
- 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.
- 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.
- 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.
- 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.
- 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.
- Check Operating Speed: Verify that the selected coupling can handle the rotational speed (RPM) of the application without exceeding its critical speed.
- 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.
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.
