Dynamic Behavior of Planetary Gear : 6th Report, Influence of Meshing-Phase

Abstract

The authors carried out experimental investigations about the dynamic load and the torque variation in two cases, in which the meshing-phases of each planet gear in a single-stage Stoeckicht planetary gear differ. The results are as follows : (i) The variation of dynamic load due to the errors per mesh in the case in which the meshing-phases of each planet gear are equal is smaller than that in the case in which they are different. But the torque variation of a higher-speed shaft in the case of the former is larger than that in the case of the latter, because the phases of the variation of dynamic load at three meshing points are equal. (ii) The modes of free vibration at the resonance frequency of ring gear change according to the meshing-phases of each planet gear.
