汽车发动机轴瓦在正常的使用和保养条件下,它的寿命还是相当长的。但因各种因素的影响,有些轴瓦却过早损坏。轴瓦的过早损坏影响汽车的正常运行,增加了维修工作量。在新型高速、大功率发动机的研制中有时也会因轴瓦的性能而影响发动机的耐久性。因此,轴瓦的损坏引起了人们的重视。笔者曾进行过汽车发动机轴瓦的使用调查,轴瓦的损坏的形式多为疲劳、擦伤(包括烧伤)等。本文就汽车发动机轴瓦的损坏形式及其原因作一介绍。
Automotive engine bearings in the normal conditions of use and maintenance, its life is still quite long. However, due to various factors, some bearings are prematurely damaged. Premature bearing damage to the normal operation of the car, increasing the maintenance workload. In the new high-speed, high-power engine development sometimes due to the performance of the bearing pads affect the durability of the engine. Therefore, the damage to the bearing pad has drawn people’s attention. I have carried out the investigation of the use of automotive engine bearings, bearing the form of damage mostly fatigue, abrasions (including burns) and so on. This article on the automobile engine bearing damage forms and their causes for an introduction.
