理论分析和实验证明,摆线齿轮的齿形修正是否合理,对摆线针轮行星减速器的承载能力有着十分重要的影响。本文所提出的负移距正等距的齿形修正方法可增加摆线齿轮与针齿同时啮合齿数,使摆线针轮行星减速器的承载能力得到大幅度的提高。此种齿形修正方法工艺简单,效果显著具有较好的实用价值。 Theoretical analysis and experimental results show that the correction of cycloidal gear tooth shape is very important for the bearing capacity of cycloidal planetary gear reducer. The proposed negative offset isometric tooth correction method can increase the number of meshing gear teeth and pin teeth, the cycloid and planetary gear reducer bearing capacity has been greatly improved. The tooth shape correction method is simple in technology and has obvious effect and practical value.
