摆线齿形的内啮合齿轮泵又叫做摆线转子泵，泵中的小齿轮和内齿轮只相关一个齿，因此这种内啮合齿轮泵不需要设置隔板。
Cycloidal tooth profile of the internal gear pump, also called cycloidal rotor pump, pump the small gear and internal gear only related a tooth, so the internal gear pump do not need to set partition.
内啮合齿轮泵中的小齿轮是主动轮，大齿轮为从动轮，在工作时大齿轮随小齿轮同向旋转。
Internal gear pump is the small gear wheel, the big gear for driven wheel, in work big gear with small gear cocurrent rotation.
本文通过对齿轮泵产生流量（压力）脉动的主要原理和影响因素进行分析，从而得到减小齿轮泵流量（压力）脉动的方法。
The main reason of these perturbations and its affecting factors were investigated and analysed, and a general methodology of perturbations reducing was developed.
