测量凸轮升程时,须采用设计凸轮轮廓曲线时的滚子半径。这主要是考虑在测量时能使测量基准(即测量滚子半径)与设计、工艺基准(即设计滚子半径)相一致,以消除由于基准不统一而带来的升程测量误差。一、升程测量误差产生的原因任何凸轮都是按照工作的要求由一个或几个升程、回程和停程所组成的。当用不同的滚子半径对凸 When measuring cam lift, the radius of the roller when designing the cam profile must be used. The main consideration is to make the measurement reference (that is, the measurement of the radius of the roller) with the design, process reference (that is, the design of the roller radius) to eliminate due to inconsistent benchmarking lift measurement error. First, the lift measurement error causes Any cam are in accordance with the requirements of the work by one or several lift, return and suspension of the composition. When using a different roller radius of the convex
