摘要

为改善精锻摆线锥齿轮的啮合性能,提出了一种基于偏差曲面的大轮齿面修形方法。以摆线锥齿轮小轮齿面为产形面,根据啮合原理获得与其具有传动关系的大轮共轭齿面方程。通过预设具有一定接触特性的偏差曲面,与共轭大轮齿面进行叠加,得到大轮目标齿面。对不同接触迹线方向的大轮齿面进行了修形设计和有限元接触分析,结果表明,内对角接触修形较其它修形方式较优,该修形方法为摆线锥齿轮大轮的精密锻造齿模设计提供了参考。

Abstract

In order to improve the meshing performance of cycloid bevel gear made by precision forging,the modification method of gear based on the deviation surface is proposed. Taking the pinion tooth surface of the cycloid bevel gear as the generating surface,the conjugating gear tooth surface equation satisfied the pre-determined transmission relationship is obtained according to the meshing principle. Based on the predesigned deviation surface with certain contact characteristics,the target tooth surfaces of gear can be obtained by superposing the deviation surfaces over the conjugate gear tooth ones. The finite element contact analysis is applied to the modification design for contact path in different directions. The simulation results show that bias correction is better than the others considering the flank contact stress,root tensile stress and contact pattern. The proposed modification method provides design reference for precision forging of the cycloid bevel gear.
