Abstract

The invention discloses a single-action oil-trapping-free vane pump. The single-action oil-trapping-free vane pump comprises a rotating shaft, a rotor and a stator, wherein the rotor is located in the stator, the rotating shaft penetrates through the rotor and is fixedly connected with the rotor, a plurality of first vane grooves and second vane grooves which are formed in the radial direction are formed in the rotor, first vanes are arranged in the first vane grooves in the radial direction in a sliding manner, the first vanes are arranged in the first vane grooves in a sliding manner and can swing in the first vane grooves in the circumferential direction of the rotor, second vanes are arranged in the second vane grooves in a sliding manner in the radial direction, the first vanes and the second vanes are evenly distributed in the circumferential direction of the rotor, and the outer ends of the first vanes and the outer ends of the second vanes abut against the inner wall of the stator. According to the single-action oil-trapping-free vane pump, the oil trapping phenomenon can be fundamentally avoided, so that vibration and noise of the vane pump are reduced.

Description

technical field [0001] The invention relates to the technical field of vane pumps, in particular to a single-acting oil-free vane pump. Background technique [0002] The pump is the power source of the system, and the uniformity of its output flow has an important influence on the performance of the system. Low noise transmission or even silent transmission is one of the development directions of hydraulic transmission. At the same time, for the comfort of the working environment and the reliability of the oil supply system, it is urgent to reduce the noise and vibration of the pump. [0003] The existing Chinese patent application publication number CN104500390A discloses a vane structure of an existing vane pump, and specifically discloses a single-acting vane pump, which includes a vane and an end cover, and also includes a rotor and a stator. A stator is provided, a rotor is provided in the stator, a plurality of blade grooves are provided on the rotor, and slidable bla...
