【正文】 ure of the oil for Hydraulic system. It is indispensable core ponents for each hydraulic system. It is very important to select a reasonable hydraulic pump, because it can effectively Reduce the energy consumption of the hydraulic system, improve system efficiency, reduce noise, improve performance and ensure reliable operation of the system. This design analysis axial piston pump. It mainly analyzed the classification of axial piston pump, on which the structure, such as the structure type of the plunger, the structure type of slipper and oil pan structure type carried out analyzed and designed, including stress analysis and calculation of their too. At the same time, the selection of materials and checking the cylinder is also critical, the type of variable institutional classification was also analyzed in this paper, finally, Drawing parts drawing and installing Assembly body use the drawing software of solidworks, and drawing them after interference testing. The future development of piston was also discussed in this paper.
