The invention has the advantages of simple installation and disassembly, simple tool, high strength, long service life, and strong versatility.
Description
Technical field
The present invention relates to boiler plant field is and in particular to a kind of boiler axial fan hub.
Background technology
Boiler plant, when using, needs centrifugal blower to be blown, to ensure gas circulation and to control flame combustion.
The wheel hub dismounting of existing centrifugal blower is difficult, and cannot be general, results in the need for being equipped with more model, is unfavorable for using.
Content of the invention
It is an object of the invention to the problem above overcoming prior art to exist, provide a kind of boiler axial fan hub, this
Invention installation and removal are convenient, simple using instrument, and intensity is high, long service life, and highly versatile.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of boiler axial fan hub, including tapered sleeve and fixed disk, described tapered sleeve is provided centrally with axis hole, described tapered sleeve
Fixed disk is arranged with taper surface, the taper surface of described tapered sleeve is radially even to be provided with some first limited impressions, described
Second limited impression is provided with the corresponding fixed disk of one limited impression, between described first limited impression and the second limited impression
It is equipped with spacing card article, described card article one end is provided with percussion projection, is set to taper sheath hole in the middle part of described fixed disk,
Described taper sheath hole is connected with tapered sleeve outer surface thread, and described fixing panel surface is additionally provided with some blade fixing holes, described leaf
The fixing in the hole of piece is provided with bolt, and one end that described bolt is located at tapered sleeve side is provided with nut, and the other end is fixed with connecting plate
Connect.
Further, described tapered sleeve material is cast iron.
Further, the material of described fixed disk and scalable reinforcement is No. 45 steel.
The invention has the beneficial effects as follows:
1st, fixed by axle sleeve and fan shaft, the fan shaft of the suitable difference diameters of axle, strong adaptability, need not single corresponding chi
Very little, installation and removal are convenient；
2nd, connecting plate is bolted to all together, increases the firmness between bolt, blade and wheel hub when running, is subject to
Power is disperseed, and reduces abrasion, more durable.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of description, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
The specific embodiment of the present invention is shown in detail in by following examples and its accompanying drawing.
Brief description

Obtain other accompanying drawings.
Fig. 1 is the overall structure diagram of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Shown in reference Fig. 1, a kind of boiler axial fan hub, including tapered sleeve 1 and fixed disk 2, tapered sleeve is provided centrally with axis hole
3, the taper surface of tapered sleeve is arranged with fixed disk, the taper surface of tapered sleeve is radially even to be provided with some first limited impressions 4, the
Second limited impression 5 is provided with the corresponding fixed disk of one limited impression, joins between the first limited impression and the second limited impression
Conjunction is provided with spacing card article 6, and card article one end is provided with percussion raised 7, is set to taper sheath hole, taper sheath hole in the middle part of fixed disk
It is connected with tapered sleeve outer surface thread, fixing panel surface is additionally provided with some blade fixing holes 8, the fixing in the hole of blade is provided with spiral shell
Bolt, one end that bolt is located at tapered sleeve side is provided with nut, and the other end is fixedly connected with connecting plate 9.Cover in order during use
Connect, after tapered sleeve and fixed disk spin, position is set by spacing card article card, tapped using hammer raised, dismantle
When similarly tap herein by spacing card article take out.
Tapered sleeve material is cast iron, and the material of fixed disk and scalable reinforcement is No. 45 steel, coordinates good fixing effect, by force
Degree is big.
Originally put and fixed with fan shaft by axle sleeve, the fan shaft of the suitable difference diameters of axle, strong adaptability, need not single corresponding chi
Very little, installation and removal are convenient；Connecting plate is bolted to together by all, when increasing operation between bolt, blade and wheel hub
Firmness, force dispersion, reduce abrasion, more durable.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple modifications to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can be realized without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
