摘要

摆线轮在齿轮测量中心上检测时采用一维测头采样机理，由于一维测头的敏感方向与齿廓法向误差定义方向不一致，导致误差计算过程繁琐，甚至误差结果不准确，不能真实地反映实际齿廓的加工形状。为此，提出了一种封闭重构方法，将其运用到RV摆线轮误差检测过程中，不仅能够精确获得摆线轮齿廓任一点的加工误差，而且误差结果能够反映齿廓的实际形状。基于封闭曲线重构理论，利用封闭曲线周期性延伸的特点，确定了首末端点节点矢量和首末控制顶点，实现重构齿廓在闭合点处完全封闭连续。在此基础上，建立误差计算模型，计算得到真实齿廓误差。通过实例对比验证了该方法的实用性和有效性，为后续精加工处理提供数据依据。

Abstract

Cycloidal gear adopts one-dimensional probe sampling mechanism when detecting on the gear measuring center. Due to the sensitive direction of one-dimensional probe is inconsistent with the definition direction of tooth profile normal error， the error calculation process is tedious， and even the error result is inaccurate， which can not truly reflect the machining shape of the actual tooth profile. For this， a closed reconstruction method is proposed and it is applied to the error detection process of RV cycloidal gear， which can not only accurately obtain the machining error of any point of cycloid gear tooth profile， but also the error result can reflect the actual shape of tooth profile. Based on the closed curve reconstruction theory， using the characteristics of the periodic extension of the closed curve， the nodal vector and control vertex of the head and end points are determined， and the reconstructed tooth profile is completely closed and continuous at the closed point. On this basis， an error calculation model is established， and the real tooth profile error is calculated. The practicality and effectiveness of this method are verified by comparison of examples， which provides data basis for subsequent finishing processing.
