摘要
提出了一种新的弧面分度凸轮廓面修形方法,建立了修形计算公式和经过修形的凸轮廓面方程。该方法可克服传统范成法加工的不足,提高弧面分度凸轮表面加工质量,又使得凸轮机构的啮合特性得到改善。所建立的修形计算公式和修形凸轮廓面方程可直接用于开发相应的弧面分度凸轮机构CAD/CAM系统软件。
A kind of novel contour modification method for arc surfaced indexing cam has been put forward, and the formula of modification calculation and the equation for cam profile surface after shape modification have been established. This method could overcome the deficiency of the traditional generation method processing and enhancing the surface manufacturing quality of arc surfaced indexing cam and also getting the meshing characteristics of cam mechanism to be improved. The being established shape modification calculation formula and the cam profile modification equation can be used directly for developing the corresponding CAD/CAM systematic software of the arc surfaced indexing cam mechanism.
