喷油泵凸轮的升程,直接关系到喷油泵的供油规律,对柴油机的性能影响很大。针对节油和减少空气污染的要求,为了获得理想的凸轮升趋,许多油泵厂正在不断地对凸轮的型线进行研究和改进。同时,在凸轮磨削中有关减少升程误差的探讨,也已成为油泵行业中的一个重要课题。本文对凸轮的磨削运动进行了动态分析,得出了凸轮磨削的动态特性对凸轮升程的磨削误差影响的规律性。我们以这种动态分析为基 Fuel injection cam lift, fuel injection pump directly related to the law, a great impact on the performance of the diesel engine. In order to save fuel and air pollution, many oil pump factories are constantly researching and improving cam profiles in order to achieve the ideal cam rise. At the same time, the discussion on reducing the lift error during cam grinding has also become an important issue in the oil pump industry. In this paper, the dynamic analysis of the grinding motion of the cam is carried out, and the regularity of the influence of the dynamic characteristics of the cam grinding on the grinding error of the cam lift is obtained. We use this dynamic analysis as the basis
