轴向柱塞泵滑靴副功率损失特性
Power loss characteristics of slipper/swash plate pair in axial piston pump
摘要
Abstract
Considering pressure-gradient flow and shear flow, the power loss model of slipper pair in axial piston pump was built to decrease energy dissipation of axial piston pump. The leakage, friction torque, leakage power loss and viscous friction power consumption of slipper under different pressures of piston chamber, shaft speeds and structure parameters were discussed. The results show that the power loss of slipper bearing is mainly due to the viscous friction and the leakage power loss is low, which causes the friction torque to increase. The influence of shaft speed on viscous friction power loss is more significant than pressure of piston chamber. When the radius ratio of slipper is set from 1.5 to 2.0, the lower radius ratio of slipper helps to reduce the leakage and viscous friction power loss. When the length diameter ratio of orifice is set from 3.50 to 8.75, the higher length diameter ratio of orifice due to the thin film thickness is useful to decrease leakage power loss, but the viscous friction power loss increases.关键词
