用在发动机上的滑动轴承通常分为两种:一种是衬瓦式薄壁轴承,形似瓦片俗称轴瓦;另一种是衬套,又称铜套,形状为空心圆柱体。衬瓦式薄壁轴承主要用于承托发动机的曲轴和连杆;衬套主要用于支承凸轮轴轴颈及活塞销。本文主要叙述的是衬瓦式簿壁轴承(轴瓦)。1.早期损坏的形式 轴承在正常使用过程中,由于逐渐磨损直到最后失去工作能力、结束其使用寿命,这种自然损伤是难以避免的。但如果因发动机装配调整不当、润滑油品质不好或使用条件恶劣等因素致使轴承过早地磨损或出现各种损伤,则是
Sliding bearings used in the engine are usually divided into two types: one is lining bush-type thin-walled bearings, commonly known as tile bearing bush; the other is bushings, also known as copper sleeve, the shape of a hollow cylinder. Liner watts thin-walled bearings are mainly used to support the engine crankshaft and connecting rod; bush is mainly used to support camshaft journal and piston pin. This article describes the main lining bush wall bearing (bearing). 1. The form of early damage In normal use, due to the gradual wear and tear until the end of the incapacity to work to end its service life, this natural damage is unavoidable. However, if the engine assembly due to improper adjustment, poor lubricating oil quality or poor conditions and other factors lead to bearing premature wear or damage, is
