测量凸轮轮廓升程时,升程起始基准的确定,目前尚未统一。本文针对这个问题,谈一些看法。一、应用尺寸公差控制凸轮轮廓形状凸轮轮廓升程的测量,属于形状公差的控制范畴。采用轮廓度公差控制凸轮轮廓升程误差,概念上是正确的,但不能只看到凸轮轮廓升程测量,在建立轮廓度公差概念之后,应采用轮廓度公差控制的一般性,而忽略凸轮轮廓升程测量,仅要求控制半径方向
When measuring the profile of the cam profile, the determination of the starting reference for the lift is not yet uniform. This article addresses this issue, to talk about some ideas. First, the application of dimensional tolerance control Cam contour shape Cam contour lift measurement, belonging to the control of shape tolerances. It is conceptually correct to use contour tolerances to control cam profile lift errors, but not just cam profile lift measurements. After establishing the concept of profile tolerances, the generality of profile tolerance control should be used while ignoring the cam profile Lifting measurement, only requires the control of radial direction
