Research on Non-Circular Planetary Gear Pump
On the basis of research on the theory of non-circular gear transmission and the working principle of gear pump, this paper puts forward the construction principle of a non-circular planetary gear pump. The discussions focus on the construction, working principle, structure types and the pitch-curve of the non-circular gears. The study indicates that the non-circular planetary gear pump has big discharge, good flow characteristics and low noise, and it can be widely used in hydraulic system.
