一、材料选择铸铁凸轮轴作为优良的凸轮轴,已在欧美国家的汽车发动机上广泛地采用着。尤其是冷激铸铁凸轮轴,更有不可忽视的优越性,主要有如下几点:1、据国外资料介绍,在不同材料和润滑情况的凸轮——挺杆摩擦副实验对比中,以冷激铸铁凸轮轴和淬火的冷激铸铁挺杆配对出现擦伤和剥落的临界负荷最高。2、同上资料表明,冷激铸铁凸轮轴和挺杆对润滑油品类不敏感。
First, the material selection Cast iron camshaft as a good camshaft, has been widely used in European and American countries car engine. Especially the cold-cast iron camshafts, there are more advantages that can not be ignored, mainly the following points: 1, according to foreign information, in different materials and lubrication of the cam - tappet friction pair experiment contrast, Cast iron camshafts and quenched chilled cast iron tappet paired with the highest critical load of galling and peeling off. 2, Ibid data show that cold shock cast iron camshaft and tappet insensitive to the lubricant category.
