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.
Based on the elastic model of a long-distance transmission roller chain, the elastodynamic analysis was taken in this paper, which has given unregulated displacement of chains. With RecurDyn software for the analysis and verification of the theoretical results, the displacement curves of X-axis, Y-axis and total displacement was obtained, which proved that the elastodynamic analysis on long-distance transmission roller chains is feasible with a continuous model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
