RV减速器的核心零件为摆线轮,摆线轮的加工也是RV减速器制造的难点。通过分析RV减速器传动中摆线针齿的传动形式对摆线轮的性能要求,确定制造摆线轮的材料为GCr15,并对摆线轮的加工工艺进行了设计。为确定摆线轮加工时的磨削余量,运用ANSYS对摆线轮的淬火工艺进行仿真分析,得到其应力场分布规律和变形情况。经实验并测量实际淬火后零件的变形情况,验证了仿真结果的可靠性。为减小热处理后摆线轮的翘曲变形,设计了摆线轮回火夹具,对摆线轮的生产加工有一定的指导意义。
RV reducer core components for the cycloid, cycloid processing is the RV reducer manufacturing difficulties. By analyzing the performance requirements of the cycloidal gear in the transmission of the RV reducer, the material of the cycloidal gear is determined to be GCr15, and the machining process of the cycloidal gear is designed. In order to determine the grinding allowance when machining the cycloid, ANSYS is used to simulate and analyze the quenching process of the cycloidal gear, and the stress field distribution and deformation are obtained. After the experiment and measurement of the actual deformation of the parts after quenching, the simulation results verify the reliability. In order to reduce the warp deformation of the cycloid wheel after the heat treatment, a cycloid wheel tempering fixture is designed, which has some guiding significance for the production and processing of the cycloid wheel.
