Simulation and Analysis of Dynamical Transmission Precision of 2K-V Cycloid pin Gear Reducer Based on Multi-Body System Dynamics

The dynamic model of multi-rigid-body system and rigid-flexible coupling system of 2K-V cycloid pin gear reducer are constructed with ADAMS, the output-angle error curves are obtained by multi-body system dynamic simulation, and the influence of elastic deformation come from planet gear, cycloid gear and pin gears on the transmission accuracy are analyzed. The work this paper introduced provides a useful approach for further study on the dynamic transmission accuracy of precision gear drive system, exploration of active control technology for the transmission accuracy and improvement of structural design for the gearing.
