摘要

摆线轮齿面加工精度是影响RV减速器运动性能的关键因素,而根据齿面误差检测数据进行机床磨削参数的反调修正更是摆线轮制造过程的重要环节。通过摆线轮展成磨削原理分析,明确了砂轮与摆线轮之间的复杂运动关系,建立了摆线轮齿面展成磨削运动关系模型,并借助于齿轮啮合理论和空间坐标转换原理,推导了以机床磨削参数为变量的摆线轮理论齿面及法矢的数学表达,为检测后齿廓误差的反调修正提供理论依据。根据构建的摆线展成磨削模型,讨论了主要磨削参数对齿面误差的影响规律。最后,与采用摆线生成原理得到的摆线轮齿廓进行了对比验证,证明了该齿廓方程表达及其建立方法的正确性。它不仅可以为摆线轮加工误差检测提供必需的理论数据,而且对摆线轮机床磨削参数的反调修正以及摆线轮齿面精度改善具有重要的理论意义。

Abstract

The machining accuracy of cycloidal tooth surface is the key factor affecting the motion performance of RV reducer,and the reverse correction of grinding parameters according to the data of tooth surface error detection is an important link in the manufacturing process of the cycloidal gear. Through the analysis of the cycloidal gear generating grinding principle,the complex motion relationship between the grinding wheel and the cycloidal gear is clarified and the model of the movement relation of the cycloidal tooth surface is established.Besides,based on the gear meshing theory and the principle of space coordinate conversion,the mathematical expression of the cycloidal gear theoretical tooth surface and the normal vector with the parameters of the grinding adjustment are deduced,which provides a theoretical basis for correcting the tooth profile error after testing.Then according to the cycloidal generating grinding model,the influence of main grinding parameters on the tooth surface error is discussed. Finally,a comparison is made with the cycloidal tooth profile obtained by generation principle,which proves that the equation and its establishment method is correct. It can not only provide the necessary theoretical data for the machining error detection of the cycloidal gear,but also have important significance for the correction of the grinding parameters and the accuracy improvement of the cycloidal tooth surface.
