Reasons for the transmission tightness of the galvanized chain

Jun 09,2025

Galvanized chains are different according to different places and methods of use. Although there are errors in use, they may be loose in specific use. So when the galvanized chain is used, the phenomenon of tightness and looseness occurs,

That's because the rollers of the galvanized chain cannot fully mesh with the tooth grooves of the sprocket. The reasons for the chain drive's erratic tightness should be considered from the following two aspects.

First, there is an error in the tooth pitch of the sprocket. Although the sprocket is processed very delicately, if it is a small batch, it is often threaded or milled to form the teeth. The roundness is made by turning, so it is easy to ensure that the tooth pitch is cut or milled, it is hard to say. The diameter of the index circle is not so guaranteed.

Second, it is possible that the pitch of the galvanized chain may have an error, so you might as well try a few more galvanized chains. However, the chain is a standard part, this possibility is relatively small. In order to consider the principle of a downstream scale caliper, when the first scale is aligned, each subsequent scale will have more errors.

If the error is large, it can even cause the chain link to face the tooth top, which will cause periodic chain drop. If the error is not so large, the cyclical tightness changes, and the error is small enough to not affect normal operation.

The above is the content compiled by the editor of the galvanized chain. For more information, please continue to pay attention to our website!
