Abstract
The utility model discloses a kind of wind wheel, comprise wheel rim and fan blade, described wheel rim end face is provided with the support in inner concave shape, described support is provided with a through hole passed for motor shaft, described bore periphery is provided with some symmetrically arranged vent holes, form barge board between described vent hole, described through hole excircle is provided with some stiffening ribs be connected with barge board, is provided with the balance set coaxial with through hole, rubber shock-absorbing circle and wear-resistant sleeve in described through hole from outer toward in.The beneficial effect of this wind wheel is: arrange balance set, rubber shock-absorbing circle and wear-resistant sleeve in through hole, when driven by motor wind wheel can be made to rotate, reduces noise, reduces vibrations, be conducive to the normal use of motor shaft and wind wheel.
Description
Technical field
The utility model relates to a kind of wind wheel.
Background technique
Wind wheel is used for parts of taking a breath of drying in electrical equipment, general wind wheel is made up of wheel rim and fan blade, the end face of wheel rim is provided with the support in inner concave shape, support is provided with through hole, and motor shaft is dismantled with Electric Apparatus Chassis through through hole and is connected, due to the frequent rotation of motor shaft, and produce between through hole and rub, the noise not only causing motor shaft to produce when rotating is large, and vibrations are large, but also greatly reduce the working life of motor shaft and wind wheel.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of noise low, shake little and life-span long wind wheel.
To achieve these goals, a kind of wind wheel designed by the utility model, comprise wheel rim and fan blade, described wheel rim end face is provided with the support in inner concave shape, described support is provided with a through hole passed for motor shaft, described bore periphery is provided with some symmetrically arranged vent holes, barge board is formed between described vent hole, described through hole excircle is provided with some stiffening ribs be connected with barge board, is provided with the balance set coaxial with through hole, rubber shock-absorbing circle and wear-resistant sleeve in described through hole from outer toward in.Balance set plays balanced action, and when making motor shaft drive wind wheel to rotate, do not rock, noise is little, shakes little; Rubber shock-absorbing circle is flexible, can reduce vibrations; The setting of wear-resistant sleeve, plays wear-resisting effect, makes the longer service life of motor shaft and wind wheel of a specified duration.
Further, described balance set excircle is provided with the scrobicular ring coaxial with balance set, described balance set excircle is also provided with some with scrobicular ring perpendicular and symmetrically arranged groove.By the setting of scrobicular ring and groove, make balance set can better and through hole combine.
Preferably, described through hole is positioned at the center of support, is positioned at central position, and during rotation, balance is optimum, shakes minimum.
Further, the cast of described wind wheel one forms.
A kind of wind wheel that the utility model obtains, its technique effect is: arrange balance set, rubber shock-absorbing circle and wear-resistant sleeve in through hole, when driven by motor wind wheel can be made to rotate, reduces noise, reduces vibrations, be conducive to the normal use of motor shaft and wind wheel.
Accompanying drawing explanation
Fig. 1 is the explosive view of a kind of wind wheel of the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of wind wheel that the utility model provides, comprise wheel rim 1 and fan blade 2, described wheel rim 1 end face is provided with the support 3 in inner concave shape, described support 3 center is provided with a through hole 4 passed for motor shaft, described through hole 4 periphery is provided with six symmetrically arranged vent holes 5, barge board 6 is formed between described vent hole 5, described through hole 4 excircle is provided with six stiffening ribs 7 be connected with barge board 6, is provided with the balance set 8 coaxial with through hole 4, rubber shock-absorbing circle 9 and wear-resistant sleeve 10 in described through hole 4 from outer toward in.Balance set 8 plays balanced action, and when making motor shaft drive wind wheel to rotate, do not rock, noise is little, shakes little; Rubber shock-absorbing circle 9 is flexible, can reduce vibrations; The setting of wear-resistant sleeve 10, plays wear-resisting effect, makes the longer service life of motor shaft and wind wheel of a specified duration.
In the present embodiment, described balance set 8 excircle is provided with a scrobicular ring 11 coaxial with balance set 8, described balance set 8 excircle is also provided with six with the perpendicular and symmetrically arranged groove 12 of scrobicular ring 11.By scrobicular ring 11 setting with groove 12, make balance set 8 can better and through hole 4 combine.
In the present embodiment, described wind wheel one cast forms.
A kind of wind wheel that the present embodiment obtains, beneficial effect is: arrange balance set 8, rubber shock-absorbing circle 9 and wear-resistant sleeve 10 in through hole 4, when driven by motor wind wheel can be made to rotate, reduces noise, reduces vibrations, be conducive to the normal use of motor shaft and wind wheel.
