随着节约能源和防止空气污染问题的提出,对车辆燃油燃烧和废气成分的要求日益重要。因此,除了对发动机零部件、特别是凸轮轴的凸轮型线在设计上不断进行研究改进之外,还必须提高其加工精度、表面质量和加工合理性。长期以来,在汽车行业中如何减小凸轮形状的加工误差,已成为一个很重要的问题。事实上,由于过去认识的局限性,加上设备条件的关系,凸轮形状误差超出规定的现象较为普遍。
With the issue of saving energy and preventing air pollution, the demand for fuel combustion and exhaust gas composition of vehicles has become increasingly important. Therefore, in addition to continuous improvement of the design of the cam profile of engine components, especially camshafts, the machining accuracy, surface quality and processing rationality must be improved. For a long time, how to reduce the machining error of the cam shape in the automotive industry has become a very important issue. In fact, due to the limitations of the past understanding, coupled with the equipment conditions, the cam shape error is more than the provisions of the more common.
