This paper uses the multi-body dynamics simulation software ADAMS, establishes the dynamics modeling of the new Hy-Vo silent chain meshing with involute sprockets, based on the analysis of the meshing mechanism of the new Hy-Vo silent chain and sprocket, the reasonable structural parameters of the new Hy-Vo silent chain are defined, and the meshing simulation of the new of Hy-Vo silent chain drive is conducted. Simulation results show that the meshing mechanism of th new Hy-Vo silent chain and involute sprockets is a new kind of meshing mechanism, due to the dual function of the variable pitch feature and meshing with involute sprockets alternately using outer and inner flanks of the link plates, which can significantly reduce the polygon effect, the meshing simulation of the new Hy-Vo silent chain and sprockets will provide an effective means of dynamic design for the Hy-Vo silent chain drive with different pitch, different number of teeth.
