摘要
通过对齿轮传动动态性能进行仿真研究,以齿轮传动为例,在测得轮齿端面和齿顶的有关数据的基础上,通过B样条曲线对齿轮的齿面进行正弦修形,并利用有限元法对其接触强度进行了分析,得到齿面接触应力的分布规律,通过比较修形齿轮和标准渐开线齿轮实测的振动加速度和噪声,证明了本优化修形设计方法对提高齿轮传动动态性能的效果显著。
Based on the simulation of the dynamic performance of spur gear transmission, the base line and the vertex of the gear teeth , the sinusoid profile relief was built with the B-spline hyperpateh. The contact stress distribution on working tooth surface was obtained by analyzing it with finite element method. The vibration acceleration and noise of testing gear were compared with those of standard involute gear on the gear dynamic transmission error test rig. The effect of the optimum gear profile modification method on improving the gear dynamic performance was identified.
