摆动滚子从动件盘形凸轮的自动化设计

在高精度凸轮的设计过程中,需要实现凸轮实际轮廓曲面的精确设计.解析法虽然可以精确计算出凸轮廓线上各点的坐标值,但要得到完整的凸轮实际轮廓曲面,需要手工编制复杂的程序,尤其是在摆动滚子推杆盘形凸轮的设计过程中,对于凸轮理论轮廓曲面的等距偏移曲面的编程更为复杂.因此以摆动从动件盘形凸轮机构为例,提出了利用解析法结合Pro/E软件的参数化设计功能进行凸轮实际轮廓曲面的精确自动化设计新方法.这一方法可以大幅度提高解析法设计凸轮实际轮廓曲面的效率,从而为解析法在凸轮机构设计方面的广泛应用奠定了基础.

Parametric design of oscillating-roller-followed disk cam

For the purpose of precision cam design, it is critical to speculate the actual cam surface. Although analytical methods could exactly determine coordinates of a cam contour, complicated programs are demanding to obtain actual cam surface contour. Especially for oscillating-roller-followed disk cam design, a parametric design method is proposed using Pro/ENGINEER TM. Compared with traditional analytical design methods, the design efficiency has been significantly promoted. Therefore, this approach improves analytical methods for cam mechanism design.
