【Abstract】 Based on the meshing characteristics of helical gear pair,the operation characteristic of helical gear pump is analyzed.Computing formula of contactratio while happening oil trapped phenomenon is proposed and a conclusion that the phenomenon of oil trapped can be eliminated by optimizing the geometric parameters of helical gear pump is obtained.The formulas of critical spiral angle and gear-width without trapped oil phenomena are given in this paper.更多还原
