Research on Port Plate of the Internal-Curve Planet Gear Pump

Abstract:

The internal-curve planet gear pump is a new type of gear pump, which is on the basis of the transmission theory of non-circular planetary train and the working principle of gear pump. In order to realize the function of hydraulic pump, it is very important to research on the port plate of the pump, and it is a key link in the process of research on the pump for the mechanical efficiency, volumetric efficiency and stability of low speed. After analysis of structure principle, movement track of planet gears and variation of oil distribution hole, the discussions focus on the position of the oil distribution holes of the port plate, as well as the number, the size of the oil distribution holes. The study indicates that the port plate designed can satisfy the internal-curve planet gear pump.
