New Design of Hy-Vo Chain Based on the Ultra-Small Rolling Radius

To improve the system meshing performance and chain stability, a totally new type Hy-Vo with an ultra-small rolling radius is proposed in this research. According to theory of rocker pin, design method for are proposed. Based on analysis model polygonal action, by calculating specific example, it proved that variable pitch characteristic controllable. Through comparing center distance fluctuations classical chain, shown both fluctuation difference running deviation all smaller chain. Combined Multi Flexible Body Dynamics (MFBD), plate stress distribution more uniform, life longer. As result, has better fatigue resistance, as well process economy. Moreover, paper not only novel structure drive, but also reveals mechanism controllable characteristic.
