内燃机滑动轴承的性能要求取决于它的用途。轴承设计的改进而带宋的轴承工作条件的变化,一般而言(虽不总是如此),会使轴承寿命的提高更加困难。要求发动机有较大的功率/质量比,会导致转速和油温的升高;要求发动机有较好的经济性,意味着需减小润滑油的粘度,使曲轴与轴承间的油膜变薄。如果制造厂要想满足轴承各种性能的变化要求,就应有一个轴承材料的开发规划。而这种规划的一个重要组成部分,就是扩大评价其性能可靠性的能力。这种评价是
Performance requirements for internal combustion engine plain bearings depend on its use. Improvements in bearing design with changes in the bearing conditions Song, in general (though not always), will make bearing life more difficult. Requires a larger engine power / mass ratio, will lead to speed and oil temperature rise; require a better engine economy, which means that the need to reduce the viscosity of lubricating oil, the film between the crankshaft and bearing thinning. If the manufacturer wants to meet the changing requirements of various performance bearings, there should be a bearing material development planning. An important part of this plan is to expand the ability to evaluate the reliability of performance. This rating is
