选择变齿厚渐开线齿轮变位系数的限制条件

Boundary Conditions of Choosing Modification Coefficients of Changing Thickness Gear pair

介绍变齿厚渐开线齿轮在设计中应满足轮齿不根切、齿顶不变尖、不产生啮合干涉诸条件来选择其变位系数,同时可以根据这些条件来确定与齿轮相啮合的假想齿条分度平面与齿轮轴线的最大交角δmax。

This paper expounds boundary conditions of choosing modification coefficients of changing tickness gear pair with parallel axes. These conditions must meet requirements of no undercut, no sharp top and no gearing in ter-ference. and calculate the maximum crossing angle of the reference plan of the connterpart rack and the gear axis.
