Rotor and hydraulic motor including the rotor

摘要

The present invention discloses a rotor for hydraulic motor comprising a plurality of vanes spacedly apart inserted into a plurality of vane slots formed on the rotor respectively, at least one groove is provided in outer edge of the rotor between the neighboring vanes, and extending inside along the axial direction of the rotor. wherein the groove has a first inner side and a opposite second inner side, and the first inner side of the groove is comb teeth-shaped. The rotor and the hydraulic motor using the rotor according to the present invention increases force bearing area by providing grooves on the rotor, so as to increase power output, lower the manufacturing cost, reduce the moment of inertia, and improve the starting speed and rotating speed.
