| Abstract: | In view of the thrust pad wear of main oil pump only in the negative differential expansion mode, an analysis on the thrust pad wear of main oil pump has been carried out in the positive differential expansion mode. Combined with the coupling structure of main oil pump, the cause of the thrust pad wear has been found in the positive differential expansion mode based on the analysis of axial motion of main oil pump. The results of analysis tally with the practical data from living example. Some suggestions to avoid thrust pad wear have been put forward simultaneously. |
