摘要

在环面渐开线齿轮加工原理的基础上,将基于连续变位的齿向修形方法应用于面齿轮传动中的圆柱齿轮,得到一种修形面齿轮副。首先,利用微分几何学与空间啮合理论推导出修形面齿轮副的齿面方程。然后,对其进行齿面接触分析（TCA）和曲率干涉检验。算例分析表明,该修形面齿轮副具有如下特点:可避免偏载现象的发生;可降低接触轨迹对安装误差的敏感程度;在啮合点处不会发生曲率干涉。最后,基于有限元方法,利用ABAQUS对其进行加载接触分析（LTCA）。

Abstract

On the basis of processing principles of torus-involute gear,the longitudinal modification method based on continuous shifting is used for the pinion in the face gear drive,a modified face gear pair is obtained. At first,based on the differential geometry theory and the space mesh theory,the tooth surface equations of the modified face gear pair are derived. Then,the tooth contact analysis（ TCA） and curvature interference inspection are conducted. The numerical example shows that the proposed novel modified face gear pair has following features of can avoid the occurrence of gear deviation load and can decrease the sensitivity of the contact path to the installation errors,there is no curvature interference at meshing points. At last,based on the finite element method,the loaded tooth contact analysis（ LTCA） is conducted by ABAQUS.
