某柴油机止推片磨损问题的分析及改进

Analysis and Improvement a Type of Engine Thrust Plate Wear

针对某机型柴油机在市场出现止推片磨损的问题,通过对止推片的装配、润滑、材质检验,轴向受力及整车配套等方面进行排查,得出止推片磨损是因为其承载的安全系数小于止推片设计要求。在此基础上,提出加大止推片承载面积来解决这个问题,经市场验证效果良好。

Based on a type of engine thrust wear in the market,this paper analysis of the thrust assembly,lubrication,material inspection,stress and vehicle support,ect.It is concluded that the thrust plate wear is due to the safety of axial force is less than the design requirement thrust plate.On this basis,it is proposed to increase the bearing area of thrust plate to solve this problem,which has been proved to be good in the marked.
