摘要

成形磨削精度高,砂轮修整灵活,逐渐替代展成磨。基于成形磨削技术,提出一种RV摆线轮分段修形方法。具体地,在工作段采用转角修形保证共轭啮合,在非工作段采用样条曲线过渡保证顶隙。该方法克服了等距+移距组合修形无法完全吻合转角修形曲线,且不满足共轭啮合条件的缺陷。分别将分段修形与组合修形应用在RV-20E的摆线轮修形中,结果显示,组合修形在工作段与目标曲线离差较大,修形效果较差,分段修行完全满足共轭啮合条件。

Abstract

Form gear grinding technology has characters of high-accuracy,it’s grinding wheel can be modified flexibly,and replaces generating method gradually. A piecewise modification method of cycloidal gear was designed based on form gear grinding technology. This method used angel modification in working section and spline curves in other spaces. The isometric and shift combination modification method can not fit angel modification curve completely and dose not meet the conjugate mesh condition.Our method overcomes these disadvantages. Both methods were applied in the example of modification cycloidal gear in RV-20 E reduce. The results show the combination modification method has a high error relative to the objective curve. The piecewise modification method meets the conjugate mesh condition completely.
