近年来,由于高负荷发动机设计技术水平的提高,主轴承和连杆轴承的负荷逐渐增大,涡轮增压器日益普及(通常配装中冷的)是促进这一趋势的一个主因。目前强调节省燃料,更加加重滑动轴承的载荷,因为柴油机制造厂家极力使较小型发动机的功率逐步提高。较高的负荷要求发动机零件全都具有更高的疲劳强度,轴承也不例外。迄今,轴承合金 In recent years, due to the high level of design technology of high-load engine, the load on the main bearing and connecting rod bearing is gradually increased, and the increasing popularity of turbocharger (usually equipped with cold) is a main factor to promote this trend. The current emphasis on fuel savings adds even more to the load on the plain bearings as diesel manufacturers strive to gradually increase the power of smaller engines. Higher load requirements all engine parts have higher fatigue strength, bearings are no exception. So far, bearing alloy
