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.
