摘　　要：为解决三环式减速器振动大、温升高和轴承使用寿命短的问题,提出了以金属环作为均载减振件,将其加在三环式减速器输入轴上,构成均载减振的完全平衡的新型三环式减速器.介绍了新型三环式减速器的结构和工作原理,分析了输入轴的内齿环板的受力公式,研究了均载环对减速器动态性能的影响,导出了动态响应方程.振动模型表明,装有均载环的新型三环式减速器属于主动隔振方式的弹性连接阻尼减振隔振装置,合理设计均载环时可改善三环式减速器的工作性能.In order to solve the problems of high vibration, high temperature and short bearing life of the three\|ring type gear reducer, a new type of three\|ring gear reducer with equilibrating load, reducing vibration and full balance is developed. The metal ring being taken as equilibrating load and reducing vibration is installed on the input shaft of the gear reducer. The structure and transmission principles of the new reducer are introduced. The formula for calculating the force on the inner ring plate is presented. The influence of equilibrating load on dynamic performances of the new reducer is analyzed, and the dynamic response equations are derived. The vibration model shows that the new three\|ring type gear reducer with equilibrating load is an active reducing vibration unit with elastic link damping reducing vibration parts. An effective method for improving work function of the new reducer is provided.
