造成连杆轴瓦故障原因很多,不同原因造成轴瓦故障的症状各不相同,但都离不开润滑理论。S195柴油机连杆轴瓦与曲轴轴颈磨擦付表面必须产生油楔间隙,将轴托起,使磨擦表面分开,这就要求作用在轴上载荷应小于油楔的承载能力,轴瓦与轴颈内表面几何形状偏差尽可能地小,破坏了这个条件轴瓦就要产生故障。 机油压力不足造成连杆轴瓦抱轴,多数为 Cause connecting rod bearing failure for many reasons, different causes of bearing bush failure symptoms vary, but are inseparable from the lubrication theory. S195 diesel engine connecting rod bearing pad and crankshaft journal friction to pay the surface must generate oil wedge gap, the shaft up, so that the friction surface separately, which requires the role of load on the shaft should be less than the carrying capacity of oil wedges, bushings and journal inner surface Geometric deviation as small as possible, under the conditions of damage to the bush will have trouble. Lack of oil pressure caused by connecting rod bearing shaft, most of them
