摘　　要：针对目前摆线泵内外转子加工精度不高,造成容积效率降低的情况,结合目前摆线泵内外转子的加工方法,并对其相对运动过程进行研究,通过改善加工工艺和设计合理的工装,提高了摆线泵内外转子重要尺寸和形位公差的精度。试验结果表明,摆线泵的容积效率明显提高。At present,the machining accuracy of inner and outer rotors of cycloidal pump is not high,resulting in the reduction of volumetric efficiency.Combined with the current machining methods of inner and outer rotors of cycloidal pump,its relative motion process is studied.By improving the processing technology and designing reasonable tooling,the accuracy of important dimensions and geometric tolerances of inner and outer rotors of cycloidal pump are improved.The test results show that the volumetric efficiency of cycloidal pump is significantly improved.
