【摘要】：针对常用组合修形方法无法同时满足高精度摆线轮高承载、低回差要求的问题,提出一种偏心距组合修形方法。在运用三坐标测量仪对RV-40E型减速器摆线轮进行精密测量的基础上,基于最小二乘法对测量所得的摆线轮齿形坐标参数进行圆弧拟合,并得到了相应的摆线轮齿形方程。然后,以所得齿形方程曲线为目标齿廓曲线,运用Matlab对"偏心距+等距+移距"、"等距+移距"、"等距+移距+转角"3种组合修形方式的所形成的摆线轮的齿形进行优化。优化结果表明,相较于"转角+等距+移距"和"等距+移距"组合修形,"偏心距+等距+移距"组合修形所得的曲线与目标齿廓曲线的偏差更小,说明了"偏心距+等距+移距"组合修形方式具有一定的可行性。
[Abstract]:Aiming at the problem that the common combination modification method can not meet the requirements of high precision cycloidal wheel with high load and low return error simultaneously. This paper presents an eccentricity combination modification method, which is based on the precise measurement of cycloidal wheel of RV-40E reducer by using three coordinate measuring instrument. Based on the least square method, the tooth profile parameters of the cycloid gear are fitted by circular arc, and the corresponding tooth profile equation is obtained. Then, the tooth profile curve is taken as the target tooth profile curve. The tooth profile of cycloidal gear formed by three combined modification modes of "eccentricity and equidistance", "isometric shift" and "isometric angle" is optimized by using Matlab. The optimized results show that the tooth profile of cycloidal gear is optimized. Compared with the combination modification of "angular isometric shift" and "isometric shift distance", the deviation between the curve and the target tooth profile curve obtained by the combination modification of "eccentricity and equidistant distance" is smaller. It is shown that the combination modification of eccentricity and equidistance is feasible.

【正文快照】： 0引言RV传动中采用的标准摆线行星传动啮合副元件由于具有较大的滑动率,且不能补偿装配误差及其零部件的制造误差,还不能形成啮合间隙而达到良好的润滑,所以无法获得良好的传动效果。为解决该问题,就必须对标准摆线齿廓进行优化和修形。近年来,国内外学者围绕摆线轮常用修形方
