Abstract
The wedge-shaped oil film thickness, pressure and temperature distribution of the valve plate pair of an axial piston pump were investigated using finite difference and relaxation iterative methods and lubrication characteristics for different working conditions and tilt and non-tilt states of the cylinder block were analysed for comparison. The oil film thickness changed when the cylinder block was tilted relative to the valve plate and produced hydrodynamic effects, increasing the carrying capacity. The structural parameter of the valve plate pair influenced lubrication characteristics. The temperature of the oil film increased and the temperature field was unevenly distributed owing to frictional power-related changes to heat energy. The simulated temperature and friction coefficient showed good agreement with measured values.
