齿轮油泵采用斜齿轮是降低机械噪声和减小流量脉动的一种有效措施。
Use of helical gear in gear pump is an effective measure, which can reduce the mechanical voice and flow pulse.
内啮合摆线转子齿轮油泵的齿形对泵的加工、性能(如：流量、脉动、噪声)等有很大的影响。
The gear form of internal gearing cycloidal gear pump has important influence on machining and characteristics of pump, such as flow rate, fluctuation rate and noise etc.
同时指出流量脉动系数最大的影响因素是油液的弹性模量和油泵的工作压力，其次是柱塞数。
Maximum influencing factors of flow fluctuation coefficient are the elastic modulus of the oil and the working pressure of the pumps, the piston number being a minor factor.
