内燃机滑动轴承大多数是动压式液体摩擦向心滑动轴承,因此它的基本计算愿则也应为:保证有足够的最小油膜厚度,把两个摩擦表面完全隔开;维持足够的润滑油流量,使润滑油能源源不断地充入油楔;限制轴承温升,使润滑油在工作状态下仍保持足够的粘度。内燃机滑动轴承的负荷是以一定的循环方式变化的,因此,它属于非稳定负荷轴承。Holland-Butenschn根据流体动力性能所建立的润源理论,提出了一套轴承设计计算的基本方法:轴心 Most of the internal combustion engine sliding bearing is dynamic pressure type liquid friction radial plain bearings, so its basic calculation should also be: to ensure that there is sufficient minimum film thickness, the two friction surfaces completely separated; maintain adequate flow of lubricant , So that a steady stream of oil into the oil wedge; limit the bearing temperature, the lubricating oil in working condition still maintain adequate viscosity. The internal combustion engine sliding bearing load is a certain cycle of change, therefore, it belongs to the unsteady load bearing. Holland-Butenschn based on fluid dynamic performance of the Run-source theory, put forward a set of basic design method of bearing calculation: axis
