Effect of Pretension on the Dynamics of Chain Drives

Abstract:

Suitable methodologies for the dynamic analysis of chain drive mechanisms, based on a multibody systems formulation in which clearance revolute joint formulation is extensively used, have been developed and implemented in a simulation code. The use of tightener systems has been recognized as the most effective way to improve the performance of chain drive mechanisms, since the occurrence of instabilities and vibration patterns of the free chain strands between sprockets can be largely reduced. As a result, these components have been extensively used in car and marine engines. Their influence on the dynamics of the system is analyzed in this article.
