Study on Tooth Micro-geometry Optimization of Rear Gear Set in 2 Speed Planetary Gear Reducer

초록

Gear tooth micro-geometry modifications include the intentional removal of material from the gear teeth flanks,so that the shape is no longer a perfect involute. If the gear shapes are perfect, then the gear tooth meshing is better,therefore the gears will transmit input torque in a more efficient manner without the generation of high frequencyengine fluctuation noise. In this paper, we study tooth micro-geometry optimization of rear gear set in 2 speed planetarygear reducers. Analysis revealed problems which are need of modification. Based on the results, tooth micro-geometrywas used to deal with load distributions on the rear gear set.
