现代汽车发动机的连杆轴承和主轴承大部份都采用钢-铝基轴瓦,其中以锡含量20％、铜含量1％的铝合金作为抗磨材料。这种轴瓦的优点已被国内外20余年的经验和使用实践所证实。轴瓦承受的单位负荷大约30MPa,与轴颈能很好地配合工作,尤其是含铅轴承,一直列大修时的临界磨损(25μm)都能保持自身的工作性能。1 汽车轴瓦部件的安装要求 安装轴瓦部件时要注意以下几点特殊要求:1.1 发动机装配时,要使用高度清洁的润滑
Most of the connecting rod bearings and main bearings of modern automobile engines adopt steel-aluminum bearing bush, of which aluminum alloy with 20% of tin content and 1% of copper content is used as wear-resistant material. The advantages of this bearing has been more than 20 years of experience at home and abroad and the use of proven practice. Bearing unit bearing unit load of about 30MPa, and the journal can work well together, especially lead-bearing, has been listed when the critical wear (25μm) can maintain their own work performance. 1 car bearing parts installation requirements When installing bearing parts should pay attention to the following special requirements: 1.1 engine assembly, the use of highly clean lubrication
