Abstract

In order to reduce the influence of meshing impact on high-speed helical face gear transmission, the expression of meshing impact force of helical face gear is derived, and the modification curve of pinion composed of parabola at both ends and a straight line is designed. An optimization model of tooth surface modification of high-speed helical face gear transmission is established, which takes the modification parameters as the optimization variables and the minimum relative speed of meshing impact as the objective. The influence of input speed and load on meshing impact of helical face gear is analyzed. The results show that when the speed of the pinion is 10000r/min and the working load is 500N·m, the reduction amplitude of the meshing impact force reaches 44.75% by optimizing the modification curve parameters of the pinion tooth surface, which effectively reduces the meshing impact force of the helical face gear pair at high speed.
