摘要
应用有限元法考察了修形斜齿轮的轮齿接触和载荷分布。根据变形协调条件和力平衡关系建立了轮齿面接触分析有限元模型。宽斜齿轮副由一个渐开线齿轮和一个双鼓形齿轮组成,建立了齿轮传动装置整体有限元模型,开发了有限元网格划分程序。应用ANSYS软件考察了修形参数对轮齿上载荷分布和接触应力的影响。
The tooth contact and load distribution of modified helical gears were investigated and analyzed by means of finite element analysis （FEA）. The face-contact model of gears was established according to the deformation compatibility condition and force equilibrium relationship. The proposed helical gear set comprised an involute pinion and a double crowned gear. Finite element models of the whole gear drive have been set up. Accordingly, a mesh-generation program was also developed for finite element contact analysis. The load distribution and contact stress were investigated by using the commercial FEA package, ANSYS. Furthermore, several examples were presented to demonstrate the influences of the gear＇ s modification parameters on the load distribution and contact stress.
