Abstract

A new pin-cycloid speed reducer with flexibility structure was designed and its nonlinear dynamic characteristics were analyzed. The eight-degree of multi-factor coupling dynamical models of traditional and the new pin-cycloid speed reducer were established by adopting theory of concentrated parameter, and vibration differential equations were built, respectively, on the basis of Newton’s second law. Then, these differential equations were solved and vibration features of pin-cycloid speed reducer were obtained. The results indicate that vertical and torsional vibration effects of cycloid gear and low-speed shaft are reduced after adopting flexibility mats. Moreover, vibration test was carried out, and experimental results are in good agreement with theoretical analysis results. The new pin-cycloid speed reducer’s vibration effect is superior to the traditional one.
