摘　　要：普通齿轮泵存在径向力不平衡,难以消去的问题。针对齿轮泵轴承寿命低,服役时间短的问题,提出将谐波式齿轮传动和齿轮泵复合的设计,解决了径向力不平衡的关键问题;阐述了谐波式齿轮泵的运行原理,确定了出油口和进油口取在相互对称的位置,从而抵消了径向液压力;分析了齿廓型式的选择,得出修形后的渐开线齿廓型式较为合适;并用简便的方法通过坐标转换分别推导出了刚轮和柔轮的齿廓曲线方程。Gear pump exists the problem that unbalanced radial force is difficult to eliminate.According to that the gear pump bearing life is low,service time is short,it put forward the method of compositing harmonic type gear transmission and gear pump,solving the key problems of unbalanced radial force.Expounding operation principle of harmonic gear pump,determining the oil outlet and inlet in the symmetric position of each other,it offset the radial hydraulic pressure.It analyzed the choice of tooth profile type,and since the shape of the involute tooth profile form is relatively appropriate,deducing the tooth profile curve equation of just round of soft round in simple method.
