Abstract
The utility model discloses a novel cycloid rotor for a pump. The novel cycloid rotor comprises a cycloid outer rotor and a cycloid inner rotor, wherein a cycloid inner contour is arranged in the cycloid outer rotor; a cycloid outer contour is arranged outside the cycloid inner rotor; an arc technical slot, a rectangular technical slot and a transmission spline are arranged in the cycloid inner rotor; the cycloid inner rotor is arranged in the cycloid outer rotor; the cycloid inner rotor and the cycloid outer rotor are in clearance fit with each other. According to the novel cycloid rotor for the pump, the cycloid outer rotor and the cycloid inner rotor are matched to do motion; when the cycloid outer rotor and the cycloid inner rotor do relative motion, the transmission spline presses and conveys normal-pressure hydraulic oil from a left side cavity of a boundary line to a right side cavity of the boundary line, so that pressure oil output is realized; the cycloid inner rotor and the cycloid outer rotor are in clearance fit with each other, so that a phenomenon of locking of the cycloid rotor caused by stamping deformation is avoided; the service life of the cycloid is effectively prolonged.
