Spherical swashplate type axial piston pump slipping shoe hole shape and reasonable position design is key points for pump working. Current calculation method which adapted average parameters as final size is not accurate in theory. In this paper ,according to the relationship between geometry and motion of piston pump, coordinate transformation is used three times to deduce motion trajectory equation,and drive motion trajectory curve. The method discussed is precise ，it can be used to provide reference for slipping shoe hole design.

This paper first analyzes the working principle and the working process of the pot-making mechanism. Then the modeling design for the parts of the pot-making mechanism is taken using the basic modeling module of Pro/E. According to the dynamics requirements of the pot-making mechanism, the modeled parts are assembled. Considering the actual working situation, these assembled parts are connected each other according to the motion patterns, thus completing the assembly of the pot-making mechanism. At last, with the help of the mechanism module of Pro/E, the dynamic trajectory of the potting knife is simulated, and the simulation results are analyzed.
