포트 형상을 고려한 제로터 펌프의 성능 해석

다국어 초록 (Multilingual Abstract)

This paper presents the performance analysis of the Gerotor pump featuring the port plate with relief grooves for reducing the pressure ripple. The inner and outer gears are conjugated to create a multiple of the chambers through which the working fluid is transported from the inlet port to the outlet port. Due to the geometric configuration of the Gerotor gears, both ends of the chambers are inevitably edge-shaped. The edge-shaped ends decrease the passage area between the chambers and ports and increase the flow resistance. Hence, the pressure inside the chamber is sharply varied and the pressure ripple is undesirably developed. In order to reduce the pressure ripple of the Gerotor pump, the passage area should be increased and the relief groove could be machined on both end of the ports. Therefore, this paper shows the performance analysis results of the Gerotor pump considering the port geometry with the viewpoints of the single chamber pressure and flowrate, the pump pressure and flowrate, as well as the shaft torque.
