以滚轮斜置式凸轮发动机的凸轮为研究对象,建立了凸轮的工作曲面方程。采用范成法对该凸轮工作面进行了加工,并用三坐标测量机对加工成型的工作面进行了实测。在凸轮工作面实测数据的基础上提出计算活塞前后滚轮中心之间距离的方法,为活塞滚轮轴孔的加工提供了依据。 Taking the cam of the roller ramp cam engine as the research object, the working surface equation of the cam is established. The method of Fan Chengfa was used to process the cam working face and the measured working face was measured by CMM. The method of calculating the distance between the centers of the front and rear rollers of the piston is put forward based on the measured data of the cam working surface, which provides the basis for the machining of the shaft of the piston roller.
