Transmission device for pump and delivery pump

The invention discloses a transmission device for a pump and a delivery pump. The transmission device for the pump comprises a shell, a main shaft, a conjugated cam set and a transmission frame, wherein the main shaft is rotationally arranged on the shell, the conjugated cam set comprises a first cam and a second cam, the transmission frame is arranged on the shell in a sliding mode, the transmission frame is provided with a first roller and a second roller positioned on the back side of the first roller, the side wall of the first roller abuts against the side wall of the first cam, and the side wall of the second roller abuts against the side wall of the second cam. Due to the fact that the conjugate cam set is arranged, a spring return structure is replaced, return fluctuation of the transmission frame can be reduced, flow low pulses can be realized, and the flow precision of liquid conveying can be improved. 本发明公开了泵用传动装置以及输送泵，其中，泵用传动装置包括壳体、主轴、共轭凸轮组以及传动架，主轴转动设置于壳体上，共轭凸轮组包括第一凸轮和第二凸轮，传动架滑动设置在壳体上，传动架上设置有第一滚轮以
