Abstract
The invention discloses a kind of roof system structure ventilation blower, its structure includes central shaft, and the top of central shaft is connected by axle sleeve is fixing with the top cover of wind ball, and the lower end of central shaft is provided with central axle threads, and the downside of central axle threads is provided with fan blade fixed support；The support bracket fastened downside of fan blade is provided with outer bearing sleeve, and the upper and lower end in outer bearing sleeve is respectively equipped with upper bearing (metal) and lower bearing, is provided with internal bearing sleeve between upper and lower bearing；The assembly that outer bearing sleeve, internal bearing sleeve and upper and lower bearing are constituted is fixed on the central shaft on the downside of fan blade fixed support by a nut.The fan blade of the present invention and wind ball can rotate in the case of without extra load, requirement to power is relatively low, thus reach energy-conservation and stable operation effect, in addition, the parts minimizing participating in rotating advantageously reduces mechanical wear, extend the service life of ventilation blower, can be widely applied to large-scale work, the public places of entertainment such as Factory Building, office building, market, movie theatre.
Description
Technical field
The present invention relates to a kind of vented exhaust equipment, particularly relate to a kind of roof system structure ventilation blower.
Background technology
It is large-scale that roof system structure ventilation blower is that one is widely used in Factory Building, office building, market, movie theatre etc.
Work, the vented exhaust equipment of public place of entertainment.
Powerroof ventilator the most all includes support, wind ball and top cover, fan blade ball be internally provided with fan blade and in
Mandrel.Rotating under the dynamic action that the fan blade impeller wind in motor or the external world provides, the gas in wind ball is subject to
Centrifugal action is discharged from fan blade impeller periphery after obtaining kinetic energy, through the guide effect of scroll casing shape wind ball,
Discharge to ventilation blower outlet, thus be internally formed negative pressure at wind ball, in suction chamber air-flow continuously from
Bottom flows into and supplements, to reach the cleaning action to room air.
But the central shaft of existing powerroof ventilator is fixed, fan blade and wind ball are all around center
Axle rotates, and is therefore easily caused fan blade and the abrasion of wind ball, shortens the service life of associated components,
Additionally, for the powerroof ventilator of power is provided for relying only on natural wind, the ventilation blower of this kind of structure
Require that bigger wind-force promotes its wind ball and fan blade to rotate, if wind-force is not enough, ventilation blower can be caused
Cannot normally work.
Summary of the invention
The invention discloses a kind of roof system structure ventilation blower, it is intended to improve existing powerroof ventilator
Existing the problems referred to above.
This invention takes following technical scheme to achieve the goal:
A kind of roof system structure ventilation blower, including central shaft, the top of described central shaft by an axle sleeve with
The top cover of wind ball is fixing to be connected, it is characterised in that the lower end of described central shaft is provided with central axle threads, described
The downside of central axle threads is provided with a fan blade fixed support, described central axle threads and fan blade fixed support
Common in order to fixing fan blade；
The support bracket fastened downside of described fan blade is provided with an outer bearing sleeve, the upper and lower end in described outer bearing sleeve
It is respectively equipped with a upper bearing (metal) and a lower bearing, between described upper and lower bearing, is provided with an internal bearing sleeve；
The assembly that described outer bearing sleeve, internal bearing sleeve and upper and lower bearing are constituted is fixed by a nut
On central shaft on the downside of described fan blade fixed support.
Further, described outer bearing sleeve is plugged in the central shaft hole of a wind ball stand, and its outer rim is provided with convex
Ring, in order to position and to support outer bearing sleeve.
The invention has the beneficial effects as follows: owing to fan blade and wind ball all rotate together with central shaft, decrease
The friction of they other any parts with ventilation blower, therefore the requirement to power is relatively low, thus reaches energy-conservation
With the effect of stable operation, additionally, the parts participating in rotating decrease, advantageously reduce mechanical wear, prolong
The service life of long ventilation blower.

Accompanying drawing is the structure sectional view of the embodiment of the present invention
Figure is labeled as: 1, central shaft, 2, axle sleeve, 3, fan blade fixed support, 4, outer bearing
Set, 5, upper bearing (metal), 6 lower bearings, 7, internal bearing sleeve, 8, nut, 9, wind ball stand, 11, central shaft
Screw thread, 41, (outer bearing sleeve) bulge loop
Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
The present embodiment provides the powerroof ventilator without motor of power for one with natural wind.
Referring to the drawings:
A kind of roof system structure ventilation blower, including central shaft 1, axle sleeve 2 and wind are passed through in the top of central shaft 1
The top cover of ball is fixing to be connected, it is characterised in that the lower end of central shaft 1 is provided with central axle threads 11, central shaft
It is common that the downside of screw thread 11 is provided with fan blade fixed support 3, central axle threads 11 and fan blade fixed support 3
In order to fixing fan blade；
The downside of fan blade fixed support 3 is provided with outer bearing sleeve 4, and the upper and lower end in outer bearing sleeve is respectively equipped with
Upper bearing (metal) 5 and lower bearing 6, be provided with internal bearing sleeve 7 between upper and lower bearing 5,6；
The assembly that outer bearing sleeve 4, internal bearing sleeve 7 and upper and lower bearing 5,6 are constituted passes through a nut 8
It is fixed on the central shaft 1 on the downside of fan blade fixed support 3.
Outer bearing sleeve 4 is plugged in the central shaft hole of wind ball stand 9, and its outer rim is provided with bulge loop 41, in order to fixed
Position and support outer bearing sleeve 4.
The operation principle of the present invention is: extraneous natural wind is blown in ball along the ball wall of wind ball, wind ball and fan blade
Wheel rotates together with central shaft 1 under the effect of natural wind, in the produced centrifugal force of rotation makes wind ball
Gas obtain and discharge from fan blade periphery after kinetic energy, through the guide effect of scroll casing shape wind ball inwall, to
Ventilation blower outlet is discharged, thus is internally formed negative pressure at wind ball, and in suction chamber, air-flow is continuously from logical
Flow into bottom blower fan and supplement, to reach the cleaning action to indoor air.
