The Effects of the Wear Elongation on the Load of a Long-Distance Transmission Chain

This paper is on the effects of the wear elongation on a long-distance transmission roller chain. It presents the formulas of load calculation and the formulaic relationship between load and wear elongation in theory, with the point-by-point calculation method and chains/sprockets gearing model. With RecurDyn software for the analysis and verification of the theoretical results, it concludes that the total tension of every chain is the sum of static load and the corresponding proportion of dynamic load, and that a logical pre-tension can effectively reduce the vibration.
