基于误差补偿的RV减速器摆线齿廓二次共轭修形方法
Quadratic conjugate modification method of cycloidal tooth profile of RV reducer based on error compensation
摘要
Abstract
A cycloid tooth profile of RV reducer secondary conjugated modification methodology that can compensate for the machining error was presented.The error compensated model was established,and then the primary modification amount was determined,and the theoretical zero backlash cycloid tooth profile was obtained.Taking the given radial clearance and backlash as constraints,the secondary modification amount was determined through the established conjugated profile optimization model,and the conjugated cycloid tooth profile was obtained.The results show that this methodology can compensate for the part error under the conditions of single error or combined error in a good quality.The determined conjugated tooth profile can improve the load distribution on the tooth surface and reduce the maximum contact stress of the cycloid gear without assembly interference and ensuring transmission accuracy.It has a significant application value in the design and assembly stage of RV reducer to reduce the processing difficulty and cost.关键词
