The assembly of journal and plain bearing liner space is too little, force of organic still oil pressure is small it is the crucial index that affects lubricant result, make lubricate because of lacking engine oil between crankshaft and plain bearing liner and bite dead invalidation, include to be pulled badly, lack lube, layer of alloy of dry attrition generation is fused, grind sliding surface to did not maintain the oily film of certain ply, and all sorts of local overload exhaustion are destroyed, cavitation erosion and V form are destroyed etc, through technology of him director diesel locomotive old experience reachs the analysis of pair of its breakdown reasons, put forward precautionary measures especially. As a result of,the burns caustic mechanism plain bearing liner to burn caustic mechanism of 1 plain bearing liner is the lube film burst between journal and plain bearing liner, cause plain bearing liner and crankshaft generation clash, below high temperature, high pressure and high rotate speed, the wear-resisting alloy layer of plain bearing liner wears away prematurely or fuse, cause plain bearing liner and crankshaft to stick thereby bite, can make the steel back of plain bearing liner and Kong Zhong produces whirligig, inlet port is jammed, carry on the back by steel again with the friction of aperture causes high temperature to make plain bearing liner burned-out further, can cause bolt to break off, happen swing a malign accident that pounds cylinder body of bad internal-combustion engine.
轴颈和轴瓦的装配间隙太小,还有机油压力低是影响润滑效果的关键指标,使得曲轴和轴瓦之间因缺少机油润滑而咬死失效,包括严重拉伤,缺少润滑油,干摩擦产生合金层熔化,磨滑面没有保持一定厚度的油膜,以及各种局部过载疲惫破坏,气蚀和V形破坏等,通过本人主管内燃机车技术多年经验及对其故障原因的分析,特提出预防办法。1轴瓦的烧损机理轴瓦烧损的机理是由于轴颈和轴瓦之间的润滑油膜破裂,导致轴瓦和曲轴产生摩擦,在高温、高压和高转速下,轴瓦的耐磨合金层过早地磨损或熔化,从而引起轴瓦和曲轴粘咬,会使轴瓦的钢背和座孔中产生旋转运动,进油孔被堵塞,再由钢背和座孔的磨擦进一步引起高温使轴瓦烧坏,并会造成螺栓折断,发生甩出捣坏内燃机缸体的恶性事故。

First, the angular velocity function and maneuver load for certain maneuver flight (including hover, dive-hike and these two combined) are set up. The simulation results of the vibration of double-disk rotor system with cantilever supported on rigid bearings show that rotor would be apparently deformed under maneuver load. Second, the performance of oil force of SFD in maneuver flight is analyzed. The results show that in maneuver flight, the SFD with centering spring will become eccentric and its oil force will be time-related and offset-related.

Second, the performance of oil force of SFD in maneuver flight is analyzed. The results show that in maneuver flight, the SFD with centering spring will become eccentric and its oil force will be time-related and offset-related. Then, SFDs are introduced into typical Jeffcott rotor system. The whole system will be statically displaced in maneuver flight and the nonsynchronous components of oil force appear in the response of rotor system.

As curvature and Reynolds number increase, the middle of horizontal profile appears sunken and the vertical profile is M-shaped. There are different profile shapes in different localities along the curved pipe.
