为研究不同轴承游隙影响RV减速器角传动误差的显著性,利用建立的包含摆线轮修形、轴承游隙、齿轮非线性接触的RV减速器动力学虚拟样机仿真模型进行仿真计算,得到在摆线轮特定齿廓修形条件下,不同轴承游隙组合形式的RV减速器角传动误差传动特性,在此基础上结合正交试验分析,探究减速器中不同轴承游隙对RV减速器角传动误差的影响敏感性和影响规律,进而可通过尺寸公差控制来设计轴承游隙,为RV减速器的设计制造提供有益参考。

To study the influence of different bearing clearance on the angular transmission error of RV reducer,the characteristics of the angular transmission error as the combination forms of different bearing clearances are obtained through applying dynamics simulation work on a simulation model of RV reducer,which containing cycloidal gear profile modification,bearing clearance and nonlinear contact of gears.By analysis of orthogonal test on the basis of above,the sensitivity and influence law of the different bearing clearance on the angular transmission error of RV reducer are analyzed.Furthermore,the bearing clearance can be designed targeted by dimension tolerance control,which provides a useful reference for the design and manufacture of RV reducer.
