Summary
This article will share the common faults and solutions of roller chains in operation for your reference.
As the most common form of transmission, roller chains have outstanding performance in various fields of transportation. If the following failures occur in the roller chain, it will affect the operation of the roller chain, and we will also provide you with the corresponding solutions.
1. Inside the chain, the sprocket and the side of the tooth are worn
When the sprocket is installed, the center is not aligned. Use a ruler to approach the side of the sprocket to recalibrate the center.
2. The chain shakes obviously
(1) Uneven running speed
Adjust chain speed; change chain tension; install anti-shake device (idler and tension device).
(2) Excessive load changes
Use hydraulic torque converter or fluid coupling.
3. Uneven wear
Replace the chain immediately and apply oil evenly.
4. Poor chain flexibility
(1) Severe overload
Reduce the load and use a chain with a high load capacity.
(2) The fuel supply method is incorrect
After cleaning the chain, oil it according to the conditions of use.
(3) Corrosion occurs
Install chain protection layer, clean and oil regularly.
(4) Installation error
Replace with a new chain, check the installation status of the sprocket and shaft, and correct it.
5. Produce abnormal noise
(1) The chain tension is too large or too small
Adjust the center distance of the sprocket so that the chain maintains the most suitable tightness during transmission.
(2) The chain and sprocket are obviously worn
Replace the chain and sprocket.
(3) The fuel supply method is incorrect
Oiling according to the conditions of use, the higher the viscosity of the lubricating oil, the lower the noise.
(4) Installation error
Check the installation status of the sprocket and shaft, and correct it.
(5) Incorrect installation of chain housing and bearing
Confirm that the chain housing is not in contact with the chain, and re-tighten the bearing bolts.
(6) Does not meet the conditions of use
Adjust the chain speed, change the chain tension, and install an anti-shake device.
6. Detooth phenomenon
(1) Severe overload
Reduce the load and use a chain with a high load capacity.
(2) The chain is severely worn
Replace the chain.
(3) There is a problem with the sprocket
Replace sprocket.
7. Roller, sleeve cracked
(1) The number of revolutions and load exceeds the normal selected value
Reselect the chain.
(2) Insufficient oil supply
Grease according to the conditions of use.
(3) The chain shakes too much
Change the tensioning device or install an anti-shake device to reduce jitter.
(4) There is a foreign body
Remove foreign objects and install protective gear.
8. Broken pin
(1) Withstand unexpected shock loads
Reselect the chain and use the buffer device to reduce the impact force.
(2) The environment is harsh and the chain is corroded
Install chain protection layer, or clean and oil the chain regularly.
9. The chain is caught in the sprocket
(1) The sprocket center distance is too long
Shorten the center distance or replace the idler.
(2) The chain is too loose
Reduce the amount of slack or replace the idler.
10. The rotation of the driven shaft is not uniform
Wrong choice of chain and sprocket. Choose a chain with a small pitch or a sprocket with a large number of teeth.
11. The chain plate is broken
(1) Unexpected shocks
Reselect the chain; use the buffer device to reduce the impact force; improve the starting method.
(2) Chain jitter
Install idler to prevent shaking.
(3) The inertia of the driven side is greater than the predicted value
Reselect the chain; increase the number of chain rows, or choose a larger chain.
