coefficient of reunion
coincidence factor
overlacoefficient

Example shows that contact ratio and overlap ratio has the effect on the volume oil and the flow pulsating ratio
本文用实例说明了齿轮啮合重合系数对齿轮泵性能参数的影响。
If the coefficient of engagement overlap decreases , the flow aggrandize , trapping volume and the flow pulsating ratio decreases
随着齿轮啮合重合系数的减小，齿轮泵的流量增大，困油容积和流量脉动率减小。
Therefore , the suitable coefficient of engagement overlap got by profile correction and addendum modification is beneficial to the output property of the gear pump
因此，对齿轮齿形进行修形和变位修正使齿轮得到合适的啮合重合系数有利于改善齿轮泵的输出特性。
Firstly the reason of interference of flank is analyzed and contact ratio and overlap ratio and the point of profile modification are calculated according to two conditions
本文首先分析了齿轮发生啮合干涉的原因，并分两种情况计算了了齿轮的重合系数和修形位置。
Then a formula about flow of the gear pump and the coefficient of engagement overlap to find is obtained by area method . through analysis contact ratio and overlap ratio has the effect on the volume oil and the flow pulsating ratio
然后采用面积法求得齿轮泵流量与齿轮啮合重合系数的关系式，研究了齿轮啮合重合系数对齿轮泵困油和流量脉动率的影响。
