In said structure, guide-track groove bottom surface is provided with shell fragment or spring makes its other end enough closely abut with stator inner hole wall energy under the effect of elastic force, guide-track groove opening end coordinates with blade the tightness strengthening and be connected between blade with guide-track groove by rubber bounding means, and this blade is one large one small structure, its little head end can axially move along this axial passage under the effect of elastic component, but its stub end then has the effect limiting the motion of its excess of stroke.
As further setting of the present utility model, described rubber bounding means is sheath structure, and the central through bore of rubber body forms axial passage.
In said structure, this rubber bounding means structure is simple, it reinforces the tightness coordinated between guide-track groove with blade.
As further setting of the present utility model, described rubber bounding means is the block rubber being placed in blade both sides respectively, what guide-track groove opening end inwall offered block rubber adaptation is embedded groove, be embedded in groove and Returnning spring is installed, block rubber one end abuts with Returnning spring, the block rubber the other end be embedded channel opening end and form spacing cooperation, the described channel opening end that is embedded has the radial catch extended inwardly, described block rubber cross section is inverted T shape structure, the vertical portion of block rubber abuts blade through being embedded channel opening end, block rubber horizontal position forms spacing cooperation in being embedded in groove and with the catch of opening end.
In said structure, gap between two pieces of block rubbers forms above-mentioned axial passage, this vibrational power flow can facilitate the insertion of blade to install, when its little head end and connecting end enter, its outer wall has squeezing action to make it open this axial passage to two pieces of block rubbers to be convenient to entering of blade, and make to coordinate tightr between the two because the elastic force of Returnning spring keeps out effect to this blade, solve in prior art the problem that gets loose.
As further setting of the present utility model, described guide-track groove inwall and bottom surface are embedded with brass wire sheet, and the local that described rotor outer periphery face offers guide-track groove is provided with outstanding projection.
In said structure, by arranging the wearing and tearing between brass wire sheet reduction blade and rotor in guide-track groove, the projection in rotor outer periphery face can compensate its intensity of losing because offering guide-track groove.
Employing such scheme, the utility model has sound construction, cooperation closely, not easily gets loose, little advantage of wearing and tearing.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model specific embodiment structural representation;
Accompanying drawing 2 is the structural representation of the utility model specific embodiment stator module;
Accompanying drawing 3 is the partial enlarged drawing of A in the utility model specific embodiment accompanying drawing 2;
Pump case 1, oil inlet passage 11, stator module 2, stator 21, rotor 22, guide-track groove 221, rubber bounding means 222, be embedded groove 223, catch 224, Returnning spring 225, projection 226, blade 23, elastic component 24, rotating shaft 3.
