摘  要:异形摆线轮齿廓提取是摆线针轮减速器设计和几何建模的难点,无法通过传统摆线轮数学公式进行齿廓设计和数据点的提取。该文通过切削加工模拟的方法得到铣削刀具运动轨迹包络图,采用图像处理的方法对铣削刀具运动轨迹包络图进行齿廓提取。这种方法大大提高异形摆线轮齿廓的获取效率,且通用性好。

Abstract: Tooth profile extraction of special cycloid gear is a difficult point in the design and geometric modeling of cycloid pin gear reducer. It is impossible to design the special cycloidal gear profile and extract data points through the traditional mathematical formula. This paper obtains the envelope diagram of milling tool motion trajectory through cutting simulation, and extract the tooth profile from the envelope map of milling tool motion trajectory using image processing methods. This method greatly improves the efficiency of obtaining the tooth profile of special cycloidal gears, with good universality.

Keywords: cycloidal wheel; profile design; image processing; contour extraction; mask
