摘 要:異形擺線輪齒廓提取是擺線針輪減速器設計和幾何建模的難點,無法通過傳統(tǒng)擺線輪數(shù)學公式進行齒廓設計和數(shù)據(jù)點的提取。該文通過切削加工模擬的方法得到銑削刀具運動軌跡包絡圖,采用圖像處理的方法對銑削刀具運動軌跡包絡圖進行齒廓提取。這種方法大大提高異形擺線輪齒廓的獲取效率,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.
