摘要： 浮杯式轴向柱塞泵中浮杯浮在滚筒板上的独特结构导致浮杯有发生倾覆的可能.结合浮杯泵的结构特点分析了浮杯在滚筒板上的运动轨迹,以及运动过程中在离心力作用下发生倾覆而导致卡死的情况.压紧弹簧可防止浮杯从滚筒板上倾斜,并且不影响浮杯的正常运动.主要介绍了压紧弹簧的设计,包括最佳弹簧半径以及柱塞孔在压紧弹簧上的位置和大小.最后运用有限元法对压紧弹簧作了仿真分析,结果表明需对压紧弹簧螺钉孔周围结构进行优化改进.

Abstract: The unique structure of a floating cup floating on drum plate in a floating cup axial piston pump leads to possibility of the floating cup overturning. In this study, combined with structural characteristics of the floating cup pump, both the trajectory of the floating cup on the drum plate and the situation that the floating cup overturns under the action of centrifugal force and leads further to stuck in the process of motion are analyzed respectively. The analysis shows that a compression spring may prevent the floating cup from tilting from the drum plate and does not affect the normal movement of the floating cup. The design of the compression spring is also introduced, including the optimum spring radius, the adequate position and size of the plunger hole on the compression spring. Finally, the compression spring is then analyzed numerically by finite element method, and the results show that it is necessary to optimize and improve the structure around the screw hole of the compression spring.
