Abstract
The utility model discloses an impeller of moving away to avoid possible earthquakes, the apron center is equipped with the wheel bore that is used for cup jointing the transmission shaft, the wheel bore includes exit end, spacing end and entry end in proper order, the diameter of exit end, spacing end and entry end increases in proper order, spacing end is provided with the spring of moving away to avoid possible earthquakes, the exit end is equipped with the steady voltage hole. The utility model discloses an install impeller the spring of moving away to avoid possible earthquakes, effectively alleviate the seismism who produces when high -speed rotatory, simultaneously, the hydraulic pressure that the steady voltage hole had balance the wheel bore inside and outside is poor, the impeller is more stable when high -speed rotation.
Description
Technical field
The utility model relates to impeller technical field, particularly a kind of shock-absorbing impeller.
Background technique
The impeller of prior art comprises blade and cover plate, the wheel bore of cover plate central is used for connection rotating shaft, but lack anti-vibration structure between this impeller and rotating shaft, impeller when High Rotation Speed because the instability of hydraulic pressure or oil pressure is that impeller produces small vibration, thus produce noise.
Model utility content
(1) technical problem that will solve
The purpose of this utility model will overcome above-mentioned shortcoming exactly, aims to provide a kind of shock-absorbing impeller.
(2) technological scheme
For achieving the above object, shock-absorbing impeller of the present utility model, comprises cover plate and blade, and described cover plate central is provided with the wheel bore for being socketed transmission shaft; Described wheel bore comprises outlet end, positive stop end and entry end successively, and the diameter of described outlet end, positive stop end and entry end increases successively; Described positive stop end is provided with shock-proof spring; Described outlet end is provided with pressure stable hole.
Further, described blade is curvilinerar figure, and described blade extends to cover plate edge from wheel bore.
Further, described cover plate and blade one-body molded.
Further, described cover plate and blade are anti-rust metal material.
Further, the extension of described wheel bore is through rounded corner process.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has the following advantages: the defect producing noise when overcoming the vane rotary of prior art because of vibrations, more stable during vane rotary.
Accompanying drawing explanation
Fig. 1 is shock-absorbing impeller leading faces structural representation of the present utility model;
Fig. 2 is shock-absorbing impeller side structure sectional view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, shock-absorbing impeller of the present utility model, comprises cover plate 1 and blade 2, and described cover plate 1 center is provided with the wheel bore 3 for being socketed transmission shaft; Described wheel bore 3 comprises outlet end 4, positive stop end 5 and entry end 6 successively, and the diameter of described outlet end 4, positive stop end 5 and entry end 6 increases successively; Described positive stop end 5 is provided with shock-proof spring 7, effectively alleviates the seismism produced when High Rotation Speed; Described outlet end 4 is provided with pressure stable hole 8, and the hydraulic difference inside and outside stabilizer hub bore 3, reduces seismism further.
Described blade 2 is curvilinerar figure, and described blade 2 extends to cover plate 1 edge from wheel bore 3, and blade 2 is contacted with liquid to the full extent, thus improves rotational efficienty.
Described cover plate 1 and blade 2 one-body molded, ensure the rigid requirements of impeller.
Described cover plate 1 and blade 2 are anti-rust metal material.
The extension of described wheel bore 3, through rounded corner process, makes its smooth surface, smooth.
Impeller of the present utility model has installed shock-proof spring, and effectively alleviate the seismism produced when High Rotation Speed, meanwhile, pressure stable hole balances the hydraulic difference inside and outside wheel bore, and impeller is more stable when High Rotation Speed.
In sum, above-mentioned mode of execution is not restricted mode of execution of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
