面齿轮磨削仿真及齿面误差分析

Face-gear grinding simulation and tooth surface error analysis

为了研究经蜗杆砂轮磨削后的面齿轮齿面误差对其啮合性能的影响,运用CATIA二次开发设计面齿轮插齿及磨齿的仿真流程,并对面齿轮插齿及齿面磨削进行加工仿真,得到经插齿和磨齿的面齿轮齿面,并对磨齿后面齿轮齿面接触和误差进行仿真。同时,加工出一定参数的面齿轮,对其啮合性能进行实验测试。通过传动误差分析,发现经蜗杆砂轮磨削的面齿轮比经插齿得到的面齿轮啮合性能要优越,因此,磨削后的齿面误差对其啮合性能影响可以忽略。

In order to study the influence of ground face-gear tooth surface error on meshing performance, the simulation procedure of face-gear’s shaping and grinding was designed using the further development of CATIA. And a machining simulation on face-gear shaping and tooth surface grinding with the use of CATIA was conducted. A tooth surface can be obtained through shaping and grinding, and then simulations were conducted on the tooth contact and error of ground face-gear. A face-gear was manufactured with certain parameters, and then an experiment test on its meshing performance was conducted. Through analyzing transmission errors, it is found that the meshing performance of the ground face-gear is superior to that manufactured by gear shaper. Therefore, the impacts of tooth surface errors due to grinding on meshing performance can be ignored.
