Abstract
The utility model discloses a novel vane pump. The novel vane pump comprises a vane pump rotor, wherein a central shaft hole is installed in the center of the vane pump rotor, a plurality of vane grooves are disposed on the circumferential surface of the vane pump rotor and one concave groove is placed on the circular arc surface between every two neighboring vane grooves of the vane pump rotor. The section bottom-edge of each concave groove is a circular arc line and adopts a circular arc as a transition with two section side-edge. Because one concave groove is placed on the circular arc surface between every two neighboring vane grooves of the vane pump rotor, the amount of materials for the vane pump rotor can be reduced greatly, so that manufacturing cost is saved, weight of the vane pump rotor is lightened, moment of inertia of the vane pump rotor is lowered, and rotation rigidity of a rotor shaft is improved.
Description
Technical field
The utility model relates to a kind of new blade pump.
Background technique
Though the blade pump structure is than the complex structure of gear pump; But because advantages such as its working pressure is higher, flow pulsation is little, stable working, noise is less, the life-span is long are widely used in professional lathe, automatic control line and the automobile steering device etc., in the low-pressure hydraulic system.But the blade pump rotor in the existing at present vane pump; Its outer surface is cylindrical; How many effects are such structure not only do not have to the intensity increase of blade pump rotor; Increase the material and the manufacture cost of blade pump rotor on the contrary, increased the rotary inertia of blade pump rotor, reduced the rotational stiffness of rotor shaft.
Summary of the invention
To the deficiency of existing technology, the utility model provides a kind of can reduce material, save manufacture cost, can reduce again blade pump rotor rotary inertia, improve the new blade pump of the rotational stiffness of rotor shaft.
For realizing above-mentioned purpose; The utility model provides a kind of new blade pump; Comprise blade pump rotor; The center of said blade pump rotor is provided with central shaft hole, offers several blade grooves on the circumferential surface of said blade pump rotor, offers a concave groove on the arc-shaped surface between per two the adjacent blades grooves of said blade pump rotor.
The base, cross section that the utility model can further be set to said concave groove is a circular arc line, and base, cross section and two sections side employing arc transition.
The beneficial effect of the utility model is: owing on the arc-shaped surface between per two the adjacent blades grooves of said blade pump rotor, offer a concave groove; Therefore can reduce the material of blade pump rotor widely; Save manufacture cost; Make that also the own wt of blade pump rotor is alleviated, and then reduce the rotary inertia of blade pump rotor, improve the rotational stiffness of rotor shaft.
Description of drawings
Fig. 1 is the front view of the utility model.
Embodiment
As shown in Figure 1ly provided a kind of new blade pump; Comprise blade pump rotor 1; The center of said blade pump rotor 1 is provided with central shaft hole 11; Offer several blade grooves 12 on the circumferential surface of said blade pump rotor 1, offer a concave groove 13 on the arc-shaped surface on the said blade pump rotor 1 between per two adjacent blades grooves 12.The base, cross section 131 of said concave groove 13 is a circular arc line, and arc transition is adopted with two sections side 132 in base, cross section 131.Owing on the arc-shaped surface between said blade pump rotor 1 per two adjacent blades grooves 12, offer a concave groove 13; Therefore can reduce the material of blade pump rotor 1 widely; Save manufacture cost; Make that also the own wt of blade pump rotor 1 is alleviated, and then reduce the rotary inertia of blade pump rotor 1, improve the rotational stiffness of rotor shaft.
