摘要

新型摆线滚针减振减速器根据传统的摆线针轮减速器,在传统偏心激波轴承和摆线轮之间加入了柔性衬垫结构,以减小和阻断电机高频波动和传动过程中产生的高频波动,提高整个设备的性能和寿命。通过对减速器的精确建模和有限元模态分析,对柔性衬垫的材料参数进行了多组对比,并进行了相应的选择。结果表明,加入柔性衬垫的新型摆线滚针减振减速器与未加橡胶衬垫的最大变形量均在正常范围内,并且有随着材料的硬度增加,出现最大变形量的阶数逐渐增加的趋势。且新型摆线滚针减振减速器能够更好地避免共振。

Abstract

Based on the traditional cycloidal pinwheel reducer,the improved new type of cycloidal needle roller vibration attenuation reducer has added a new structure called flexible pad,which would reduce and prevent the high frequency fluctuations of a motor and the high frequency fluctuations produced in the transmission process,the whole performance and life of the equipment can be improved. The corresponding comparison and choice of the material parameters for the flexible pad is carried out through accurately modeling and finite element modal analysis. The results show that the maximum deformation of all the comparative reducers are in the normal range,and with the increase of the materials hardness,the maximum deformation order has gradually increasing trend. The new type of cycloidal needle roller vibration attenuation reducer which added the flexible pad,will be better able to avoid resonance.
