Measuring Chain Elongation

Measuring Chain Elongation

1. In order to remove the play of the entire chain, it is measured under a certain degree of pulling tension on the chain;

2. When measuring, in order to minimize the error, measure in the 6-10 section (link);

3. Measure the number of the inner side L1 and the outer side L2 between the number of rollers to determine the size L = (L1 + L2) / 2;

4. Find the elongation length of the chain, which is in contrast to the use limit of the chain elongation of the previous item:

Chain elongation = judgment size - reference length / reference length * 100%

Base length = chain pitch * number of sections
