Development of a New Tooth Profile Designed for High Efficiency P/M Internal Gear Pump Rotors
Inui Naoki,Ogata Daisuke,Sasaki Harumistu 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1
We developed a new tooth profile designed for P/M internal gear pump rotors. The theoretical discharge volume of the new tooth profile internal gear rotors is more than 10% higher than that of the same size conventional rotors. Our new profile rotors can achieve a decrease in torque, and fuel-efficiency will also be improved.
