Abstract
The utility model discloses a vane pump rotor, and belongs to the technical field of the machinery manufacturing. The vane pump rotor comprises a vane pump rotor body with two ends provided with stepped shafts, wherein the vane pump rotor body is provided with odd vane grooves along the warp direction, and the vane grooves are uniformly arranged on the outer circle of the vane pump rotor body. The vane pump rotor is characterized in that the bottom of each vane groove is provided with groove bottom holes, every two adjacent groove bottom holes in the same vane groove keep the same hole pitch, and the groove bottom holes in any two vane grooves are corresponding in position, and are communicated. The vane pump rotor has the advantages of simple and reasonable structure, low cost and easiness in manufacturing. The bottoms of the vane grooves are provided with the vane bottom holes, and the bottoms of the groove bottom holes of the same circumference are communicated to enable liquid among vanes and the vane grooves to flow. When the vane of the vane pump operates, the resistance is reduced, the power is uniformly supplied, the vibration and the tilting of the production in the operation are obviously reduced, the power utilization rate is enhanced, and the service lives of the vane pump body and the vanes are prolonged.
Description
Technical field
The utility model relates to a kind of blade pump rotor, belongs to machinery manufacturing technology field.
Background technique
In the multiple-blade vane pump, blade is up and down in rotor slot of vane pump is to rotate by vane pump the centrifugal force that produces to provide at present.Because the blade groove bottom land does not have the phase through hole, this just makes the liquid between blade and blade groove be difficult to flow, blade resistance when work strengthens, cause the blade of vane pump easily to produce vibrations, inclination, inhomogeneous for power when work, power utilization is low, make vane pump produce vibrations, noise, thereby make vane pump cylinder body and blade infringement.Therefore be badly in need of a kind of cost low, using effect is good, the blade pump rotor that liquid is flowed between blade groove mutually.
The model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides the liquid between a kind of blade and blade groove to flow, and blade working is shockproof, the blade pump rotor that power utilization is high.
The purpose of this utility model is achieved through the following technical solutions: blade pump rotor, comprise that two ends are respectively equipped with the blade pump rotor body of Step Shaft, the warp direction of described blade pump rotor body is provided with blade groove, blade groove add up to odd number, blade groove is arranged on the cylindrical of blade pump rotor body equably, it is characterized in that, each blade groove bottom land is provided with the bottom land hole, the hole pitch in adjacent two bottom land holes equates in same blade groove, and the bottom land hole site correspondence in any two blade grooves communicates.
Each blade groove bottom land is provided with two tapped holes that are used for assembling required part.
Described blade pump rotor body is processed into by metal cylinder.
The utility model is simple and reasonable, cost is low, easily make, because the blade groove bottom land is provided with the bottom land hole, and communicate at the bottom of the hole between each bottom land hole on same circumference, liquid between blade and blade groove can be flowed, vane pump blade is drag reduction when work, and is even for power, the vibrations, the inclination that have produced when obviously having reduced work, power utilization improves, and extends the life-span of vane pump cylinder body and blade.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 be in Fig. 1 A-A to the sectional structure schematic diagram;
Fig. 4 be in Fig. 1 B-B to the sectional structure schematic diagram;
In figure: 1 Step Shaft, 2 bottom land holes, 3 tapped holes, 4 blade pump rotor body cylindricals, 5 blade grooves.
Embodiment
Blade pump rotor comprises that two ends are respectively equipped with the blade pump rotor body of Step Shaft 1, and the blade pump rotor body is processed into by metal cylinder.
On blade pump rotor body cylindrical 4, become odd number to have equably a plurality of blade grooves 5 along warp direction again.The warp direction that is the blade pump rotor body is provided with blade groove 5, blade groove add up to odd number, blade groove is arranged on the cylindrical of blade pump rotor body 4 equably.
In the bottom of each blade groove 5, process that hole pitch equates and in the bottom land hole 2 that laterally communicates, liquid is flowed in each blade groove 5.Be that each blade groove bottom land is provided with the bottom land hole, on same blade groove, the hole pitch in adjacent two bottom land holes equates, the bottom land hole site correspondence on any two blade grooves communicates.
Each blade groove bottom land is provided with two tapped holes 3 that are used for assembling required part.
Blade is put into blade groove, can make liquid pass through bottom land hole 2 when vane pump is worked and flow between blade groove.Resistance, noise and vibrations when the utility model has reduced vane pump blade work can obviously improve power.
Claims (3)
1. blade pump rotor, comprise that two ends are respectively equipped with the blade pump rotor body of Step Shaft, described blade pump rotor body be provided with in the radial direction blade groove, blade groove add up to odd number, blade groove is arranged on the cylindrical of blade pump rotor body equably, it is characterized in that, each blade groove bottom land is provided with the bottom land hole, the hole pitch in adjacent two bottom land holes equates in same blade groove, and the bottom land hole site correspondence in any two blade grooves communicates.
2. blade pump rotor according to claim 1, is characterized in that, each blade groove bottom land is provided with two tapped holes that are used for assembling required part.
