Optimization design of the inner radius of the sealing surface of slipper

A dynamic lubrication model is built based on the lubrication theory of the oil film for optimization design of the inner radius of the sealing surface of slipper, considering the macro and micro motion of the slipper. Reasonable design criterion is presented, adopting the oil film characteristics, dynamic stiffness and minimum power loss as the optimum conditions. Furthermore, the experiments of the pump efficiency are done under the given working conditions. The results suggest that the pump with optimized slippers obtains the better oil film characteristics and efficiency, and the proposed design criterion could be applied as references for slipper/swash-plate pair design.
