由于发动机不断强化,轴瓦负荷不断增加;发动机的转速不断提高,机油温度有所增加;降低使用成本,用低粘度的润滑油等原因,都使曲轴轴承里的油膜厚度减小。因而在过去几年里,国外对曲轴轴颈表面的磨纹形状和它对轴瓦磨损的影响的研究,越来越重视了。 通常用标准的磨纹形状检查设备(Taly- As the engine continues to strengthen, bearing load continues to increase; the engine speed continues to increase, the oil temperature has increased; lower operating costs, with low viscosity lubricants and other reasons, so that the crankshaft bearing oil film thickness decreases. Therefore, in the past few years, more and more attention has been paid to the research on the effect of abraded shape of crankshaft journal surface and its wear on the bearing bush. Usually with a standard grinding shape inspection equipment (Taly-
