The flux characteristics of ordinary helical gear pump are lucubrated by theory for the first time,on this condition the selective qualification of the helical gear pump is gained. The researchful results indicate that the flux pulse ration of ordinary helical gear pump without clearance is less than that of the gear pump with clearence under the condition that the main parameters are same,and the flux pulse ration of ordinary helical gear pump is less than that of whole profile meshing helical gear pump.3.
研究结果表明：在主要参数相同的情况下，普通斜齿齿轮泵无侧隙时流量脉动率小于有侧隙时的流量脉动率；全齿廓啮合斜齿轮泵比普通斜齿轮泵的流量脉动略小。
