Abstract

Due to the high flow pulsation，the ordinary gear pump has large vibration, noise. A new structure named multi-gear pump was proposed. The model of the pump was established. The motion simulation was given to compare with common gear pump. The simulation analysis show that the pump tooth contact force pulse value is 0.296, which is about 25% lower than the common gear pump. Findings from the paper are supposed to provide a theoretical basis for the following experiments and to improve the life of gear.
