    Abstract
  • To explore the distribution law of oil film temperature field at slipper pair for axial piston pump, a thermodynamic model of slipper pair was built through the conservation law of heat flux after analyzing its transfer mechanism in detail. The effects of slipper structure parameters on film temperature under different piston chamber pressure and shaft rotational speeds were discussed. The results show that the film temperature distribution is non-uniform and show decreasing tendency along slipper radius. The maximum film temperature takes place in the slipper region where oil film thickness is thinnest. The phenomenon occurs mainly in discharge stroke, and causes slipper partial abrasion. When the slipper radius ratio is set from 1.5 to 2.0, the smaller radius ratio is selected to decrease film temperature and improve slipper lubrication performance under high shaft rotational speed. When the orifice length diameter ratio is set from 3.50 to 8.75, the lower orifice length diameter ratio is useful to decrease film temperature and improve the cooling effect of pump.
