主油道位于曲轴的发动机润滑系统故障研究

在以曲轴中心作为主油道的发动机润滑系统中,主油道直接向连杆轴颈供油,使活塞连杆组零件的润滑条件大大改善。但在静止油道向旋转油道供油的过程中,存在一个泄露间隙。在维修过程中正确处理这一间隙是保证机油压力正常的关键。对容易出现的问题进行了系统的研究,并给出了解决方案。

Malfunction Study on Lubricating System Whose Main Oil Passage is in the Crank Shaft

In the lubricating system which main oil passage is in the crank shaft, the main oil passage feedes oil to the connecting rod neck directly, so the lubricating condition of the piston and connecting rod improved greatly. But in process providing oil from motionless passage to revolution passage, there is a disclose gap, it is very important to handle this gap in repair work. Have carried out systematic research on problems which easy to appear , have given methods to thses problems.
