antiwear durability of new type Hy-Vo chain is studied and the computational method of Hy-Vo chain length accuracy is provided.The experiment result shows that the computational method of chain pitch is scientific and practical.The chain initial length becomes longer with the pre-stretch force growing larger
should be measured by the method of output force measurement due to the noncircular cross-section
the joint rigidity of pins and guide plates.The antiwear durability of the Hy-Vo chain is good under the same working condition
