Leaf Chain Manufacturers Introduces The Common Faults Of Roller Chains

Do Leaf Chain Manufacturers introduce what are the common faults of roller chains?

1. Sprocket teeth wear: If there is obvious wear on both sides of the sprocket teeth, the transmission alignment is not good. If there is a "curved groove", it means that the sprocket should be replaced with excessive wear. You can also install the sprocket backward so that the lighter wear side faces the chain. It is best to replace the excessively worn sprockets together with the chain.

2. Pin shaft wear: Usually, pin shaft wear is caused by insufficient lubrication. Always check whether there is an abrasive in the lubricating oil or change the lubrication method.

3. Chain plate side wear: If the inner surface of the chainplate of the inner link is severely worn, it means that the transmission is not aligned. The solution is to check the alignment of the shaft and the sprocket. If there is no problem with the installation, you can observe whether the rigidity is insufficient due to excessive load and deformation during operation.

4. Chain jitter: The reason for the jitter of the roller chain is that the chain is too loose, the load is too large, or one or more chain links are not flexible. The solution is to install a chain tensioner or an adjustable center distance. Reduce the load if possible.

5. Chain and sprocket coordination: If the chain and sprocket do not fit well, it may be that the hinge of the chain is worn and the pitch is elongated. If there is a phenomenon of tooth skipping, the chain should be replaced in time. If the sprocket is worn out, replace it to avoid damage to the new chain.

6. Excessive running noise of the roller chain: the excessive noise is caused by the non-coplanar sprocket; the chain tension is too large or too small; the lubrication is insufficient; the chain and the sprocket are worn out, or the chain pitch is too large. The solution is to check the coplanarity of the front and rear axles parallel to the sprocket and correct them. Adjust the center distance and tensioning device to obtain proper tightness and ensure lubrication to the workpiece.

7. Roller chain tension: the chain tension is related to the drooping distance of the loose edge of the chain. For horizontal and inclined transmission with adjustable center distance, the sag of the loose edge of the chain should be 2% of the center distance. If the centerline is driven vertically or subjected to vibration load, the reverse drive should make the chain more tensioned.
