Abstract
The invention discloses a vane pump which comprises a rotor, a positioning ring, a stator, vanes, an oil inlet and an oil outlet and is characterized in that the rotor and the stator are positioned on different axes; the rotor is driven by a shaft sleeve of a hydraulic torque converter pump wheel to take the rotary motion; the positioning ring is arranged outside the rotor; the stator is arranged outside the positioning ring; and the vanes are arranged on the periphery of the rotor. By changing the diameter of the rotor and the width of the rotor, the larger the eccentricity of the rotor and the stator is, the higher the discharge capacity of the vane pump is, so that the vane pump has high volumetric efficiency.
Description
Technical field
The present invention relates to a kind of oil pump, especially a kind of vane pump.
Background technique
Though most of oil pump of selling in the market is simple in structure, also has the shortcoming that pump duty is inhomogeneous and volumetric efficiency is low.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of vane pump in order to solve the deficiency of existing technology.
Technological scheme: in order to realize above purpose, a kind of vane pump of the present invention comprises rotor, positioning ring, stator, blade, filler opening, oil outlet, it is characterized in that: stator and rotor be not on same axis.Described rotor is driven by the axle sleeve of fluid torque converter pump impeller, and around its center rotation, described positioning ring is positioned at the outside of rotor; Described stator is positioned at the outside of positioning ring; Stator and rotor decentraction have certain throw of eccentric between the two, described blade is connected with rotor.
Beneficial effect: vane pump provided by the invention, it is even to have a pump oil flow, the advantage that volumetric efficiency is high.
Description of drawings
Fig. 1 is a structural representation of the present invention at present;
Wherein 1, rotor, 2, track ring, 3, stator, 4, blade, 5, filler opening, 6, oil outlet.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention.
Vane pump as shown in Figure 1 comprises rotor 1, positioning ring 2, stator 3, blade 4, filler opening 5, oil outlet 6, it is characterized in that: stator 3 and rotor 1 be not on same axis.Described rotor 1 is driven by the axle sleeve of fluid torque converter pump impeller, and around its center rotation, described positioning ring 2 is positioned at the outside of rotor 1, and the outside of described positioning ring 2 is provided with stator 3.When rotor 1 rotation; Blade 4 outwards opens under the effect of the working oil pressure of centrifugal force or blade 4 bottoms, abuts against on stator 3 internal surfaces, and along with the rotation of rotor 1; Reciprocating in rotor vane groove, between per two adjacent blades, just form the active chamber that seals like this; If rotor 1 rotates toward the clockwise direction, increase gradually at the working chamber volume of rotor 1, so that produce certain vacuum with the right-hand part of stator 3 lines of centres, working oil is sucked from filler opening; Working chamber volume in line of centres left side reduces gradually, and working oil is extruded from oil outlet 6.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
