Abstract
The utility model relates to the technical field of machinery, in particular to a vane structure of a vane pump. The vane structure comprises long vanes, bent structures and short vanes. Four long vanes and four short vanes are arranged at intervals, and the bent structures are arranged at the front ends of the four long vanes respectively. Compared with the prior art, the vanes of different sizes are adopted, and the bent structures are added to the front ends of the long vanes, so that the working volume of the vanes of the vane pump is increased, an oil body in a cavity of the vane pump is fully driven, and the problem of nonuniform density of the oil body in the cavity of the vane pump is solved.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of blade structure of vane pump.
Background technique
Under the effect of centrifugal force and pressure, the blade of vane pump rotates and forms swept volume with stator inner surface.If the cavity volume of vane pump is excessive, just can not fully the oil body in the vane pump cavity fully be driven during the blade rotation.Like this, can cause the interior oil body density unevenness of vane pump cavity.Therefore, a kind of blade structure that can fully drive oil body in the vane pump cavity of design is vital.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes existing technology, and a kind of blade structure that can fully drive oil body in the vane pump cavity is provided.
In order to achieve the above object, the utility model comprises linear leaf, bending structure and short blade, it is characterized in that: four linear leafs and four short blades are provided with at interval, and the front end of four linear leafs is respectively equipped with bending structure.
The utility model is compared with existing technology; Adopt blade different in size and increase bending structure at the linear leaf front end; The swept volume of vane pump blade is increased, thereby the oil body in the vane pump cavity is fully driven, solved the problem of the oil body density unevenness in the vane pump cavity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Referring to Fig. 1,1 is linear leaf; 2 is bending structure; 3 is short blade.
Embodiment
Combine accompanying drawing that the utility model is done further describes at present.
Referring to Fig. 1, the utility model comprises linear leaf, bending structure and short blade.Four linear leafs 1 and four short blades 3 are provided with at interval, and the front end of four linear leafs 1 is respectively equipped with bending structure 2.
The utility model is when work, and under the drive of vane pump, linear leaf 1 rotates with short blade 3; Because linear leaf 1 is different with the length of short blade 3; The front end of adding linear leaf 1 is provided with bending structure 2, and the swept volume of blade is increased, and is provided with at short blade 3 and front end under the drive of linear leaf 1 of bending structure 2; Oil body in the vane pump cavity is fully stirred, and has solved the problem of the oil body density unevenness in the vane pump cavity.
