On the Kinematics and Statics of Planetary Simple Gear Reducers

Abstract:

The power system equipped in machinery contains power source (motor or engine) and gear reducer to get large output torque. The rotation speed of motor is made higher and higher to attach high power with the same volume. Hence, the reduction ratio of gear reducer is required to be higher and higher. Planetary gear trains can be used as the gear reducers with high reduction ratio. However, the planetary gear train with high reduction ratio is compound gear system. This paper proposes planetary simple gear reducers with high reduction ratio. According to train value equation, the kinematic design of planetary simple gear trains with high reduction ratio is accomplished. Some design examples are designed to illustrate the design algorithm. Also, in this paper, the static force analysis is carried out to prove the kinematic design is right. Based on the proposed algorithm, all planetary simple gear trains with high reduction ratio can be synthesized.
