Pump drive shaft and bushing wear, the toleranceclearance increases, will affect oil pump.
齿轮泵主动轴与衬套磨损后，其配合间隙增大，必将影响泵油量。
2
For needle roller bearings without inner ring, a suitable internal clearance is achieved by selecting the appropriate tolerance for the raceway diameter.
对于无内圈滚针轴承，通过为滚道直径选择合适的公差，可得到合适的内部游隙。
3
Objective To investigate the incidence of delayed clearance of triglyceride rich lipoproteins(TRL) by fat tolerance test(FTT) in pilots and its effect on plasma lipids.
