Product Description

Roller chain couplings have the advantages of simple structure, convenient loading and unloading, large torque transmission, and easy operation. However, there is significant wear between the chains, especially during high-speed operation when the radial motion generated by centrifugal force will accelerate their wear. Therefore, it is not suitable for use at high speeds and under impact loads, nor for the connection of vertical shafts.

When designing the overall structure of the coupling, full attention should be paid to the lubrication and dust prevention between the tooth surface and the rollers, and an outer shell should be added. In addition to dust and oil storage, it also has a protective effect. Because if the chain breaks, it may cause personal accidents.

The double row sleeve roller chain coupling has formed a standard (old standard GB6069-85, new standard GB/T 6069-2002). The transmission torque and allowable speed are 4 times and 2 times that of a single row roller chain of the same size, respectively. Because when the chain size is determined, it can accommodate 2 teeth within the width of a single row of sleeve rollers, while a double row can only accommodate 1 tooth, the tooth thickness of a single row is only half of that of a double row. So, the rollers of the double row chain are located in the grooves of the main and driven sprockets, and when subjected to force, they rotate independently without interfering with each other, reducing wear.

chain coupling

Can chain couplings accommodate parallel misalignment?

Yes, chain couplings are designed to accommodate a certain degree of parallel misalignment between the connected shafts. Parallel misalignment refers to the situation where the axes of the two shafts are not perfectly aligned and run parallel to each other but at a distance.

Chain couplings have some inherent flexibility that allows them to tolerate a certain amount of parallel misalignment. The flexibility is primarily provided by the roller chain, which can compensate for small parallel displacements between the shafts. This flexibility helps to reduce stress on the coupling components and allows for smooth operation even in the presence of parallel misalignment.

However, it is important to note that chain couplings have limitations in terms of parallel misalignment. Excessive parallel misalignment beyond the specified limits can lead to increased stress, uneven load distribution, accelerated wear, and potential coupling failure. The manufacturer’s specifications and guidelines should be followed to ensure that the parallel misalignment remains within the acceptable range for the specific chain coupling being used.

Proper alignment during installation is crucial to minimize parallel misalignment. The shafts should be aligned as closely as possible to ensure optimal performance and longevity of the chain coupling and the connected machinery or equipment. In some cases, additional measures such as shims or adjustable mounts may be necessary to achieve the desired alignment.

Regular inspection and maintenance of the chain coupling are also important to identify and address any parallel misalignment issues that may arise over time. If significant parallel misalignment is detected, corrective measures should be taken to realign the shafts or consider alternative coupling options that are better suited for parallel misalignment requirements.

In summary, chain couplings can accommodate a certain degree of parallel misalignment, but excessive misalignment should be avoided. Proper alignment during installation and adherence to manufacturer’s guidelines are essential for ensuring optimal performance, reliability, and longevity of the chain coupling and the connected machinery or equipment.

How to install a chain coupling?

Proper installation of a chain coupling is crucial for ensuring its optimal performance and longevity. Here are the steps to follow when installing a chain coupling:

  1. Prepare the Work Area: Before beginning the installation, ensure that the work area is clean and free from any debris or contaminants. This will help prevent any damage to the coupling components during installation.

  2. Inspect the Components: Carefully inspect the chain coupling components, including the sprockets, roller chain, connecting pins, and bushings or bearings. Check for any signs of damage or wear. Replace any components that are worn or damaged.

  3. Position the Coupling: Position the coupling on the shafts that need to be connected. Ensure that the shafts are aligned properly and the coupling is centered between them.

  4. Install the Sprockets: Slide the sprockets onto the shafts, with the teeth facing each other. Make sure the sprockets are securely seated on the shafts and aligned with each other.

  5. Connect the Roller Chain: Loop the roller chain around the sprockets, ensuring that it is properly engaged with the sprocket teeth. Connect the ends of the roller chain using the connecting pins. Insert the connecting pins through the pin holes in the chain links and secure them with retaining clips or other fasteners.

  6. Tension the Chain: Adjust the tension of the roller chain to the manufacturer’s specifications. The chain should have the appropriate amount of slack to allow for smooth operation and accommodate misalignment but should not be too loose or too tight. Follow the manufacturer’s guidelines for determining the correct chain tension.

  7. Secure the Bushings or Bearings: If the chain coupling uses bushings or bearings, ensure they are properly installed in the bores of the sprockets and provide a secure and smooth rotation of the shafts.

  8. Apply Lubrication: Apply the recommended lubricant to the roller chain and sprockets. Proper lubrication is essential for reducing friction, wear, and noise, and it helps ensure smooth operation of the chain coupling.

  9. Check Alignment and Rotation: Once the chain coupling is installed, check the alignment of the shafts and the rotation of the coupling. Verify that the coupling rotates smoothly without any binding or interference.

  10. Inspect and Test: After installation, thoroughly inspect the entire chain coupling assembly. Look for any signs of misalignment, unusual noise, or vibration. Test the coupling’s operation by running the machinery at a low speed and gradually increasing to the normal operating speed. Monitor the coupling for any issues or abnormalities.

Following these installation steps will help ensure a proper and secure installation of the chain coupling, promoting efficient power transmission and minimizing the risk of premature failure or damage.
