【摘要】 在进行齿轮传动动态性能仿真研究的基础上，根据齿数、模数、齿宽、齿形、负载和转速等因素对齿轮传动动态性能的影响规律，以一对直齿圆柱齿轮传动为例，对于直线修形、抛物线修形和正弦修形，优化了齿轮传动动态性能的突出效用。更多还原

【Abstract】 Based on the simulation of the gear transmission system s dynamic performance, the profile modification curve (line, parabolic and sinusoid) of a pair spur gear transmission is optimized according to the influence law. Being compared with the regular involute spur gear, the modified gear with the optimum profile has the best dynamic performance.更多还原
