在二冲程循环柴油机中，传统的轴向油槽十字头销轴承总是受到单向载荷的小振幅振荡，润滑条件十分苛刻。本文对传统轴承和偏置轴承的润滑特性进行了理论分析。比较了两个轴承之间的油膜行为。此外，还研究了每种轴承的设计准则。利用动载试验装置，研究了轴承类型和轴承材料对轴承抗癫痫和抗疲劳性能的影响。从理论和实验工作中发现，偏置轴承的承载性能优于常规轴承，铝合金是这种轴承的合适材料。
The lubrication of a conventional crosshead-pin bearing with axial oil-grooves in a two-stroke cycle diesel engine is quite severe condition, since the bearing is always subjected to the unidirectional load with small amplitude of oscillation.This paper reports the theoretical analyses on the lubrication characteristics for the conventional and the offset bearing. The oil-film behaviour between the two bearings is compared. Moreover, the design criteria for each bearing are investigated.Experimental tests are carried out to examine the influence of bearing type and bearing material on anti-seizure and anti-fatigue by using a dynamic load bearing apparatus.From the theoretical and the experimental works it is found that the bearing performance of the offset bearing is superior to that of the conventional bearing and aluminum alloy is suitable material for this kind of bearing.
