【摘要】 针对一些发动机凸轮测量选择测量基准和确定测量位置方法中存在的问题进行了分析,并参照国家标准GB/T 1182—2008的通则要求,从发动机凸轮升程和转角是非线性函数关系入手,论述了凸轮基准选择原则和确定凸轮测量位置(起始转角)的方法,以及对凸轮测量中的测头替(转)换,测点布局等问题进行了分析。更多还原

【Abstract】 Some engine cam measuring select measurement reference and measurement method of determining position of existing problems are analyzed.According to the requirements of the national standard GB/T 1182-2008’s general rules,the lift and rotation from the engine cam of non-linear function is discussed and the selection principle and basis for cam measuring position(starting angle)method are determined.The cam measure head for change and problem of the distribution of measuring points are analyzed.更多还原
