Abstract
The invention discloses a corrosion-resisting hub with a hub sleeve. The corrosion-resisting hub comprises a hub body. The hub body is fixed to a main shaft through a spindle stop dog and a round nut. A cavity is formed in front of the hub body. The spindle stop dog and the round nut are arranged in the cavity. The cavity is sealed by a pressing plate. A sealing portion is arranged outside the hub body. The hub sleeve is arranged between the hub body and the sealing portion. The corrosion-resisting hub with the hub sleeve is novel in design and simple in structure. The cavity is formed in front of the hub body and used for containing the spindle round nut used for connection between the main shaft and the hub body. Contact between a spindle and corrosive gas is effectively avoided, and normal operation of a draught fan is guaranteed.
Description
Technical field
The present invention relates to centrifugal blower, what be specifically related to is a kind of wheel hub of corrosion resistant belt wheel hub sleeve.
Background technique
The main structural components of centrifugal blower is impeller, casing, main shaft and reel, centrifugal blower is widely used in the ventilation of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building, the ventilation of boiler and industrial furnace and air inducing, cooling in the apparatus of air conditioning and domestic electric appliance and ventilation, the oven dry of cereal and selecting and recommending, these all embody the significance of centrifugal blower.The also ventilator of emphasis application specific use, as corrosive resistant fan etc., this kind of blower fan is comparatively special in material, as stainless steel
blower fan, glass fibre reinforced plastics
blower fan, plastics
blower fan, titanium material
blower fanand metal line with rubber
blower fan.
Wheel hub is the vitals connecting impeller and main shaft, and conventional boss is when carrying corrosion-prone medium, and be difficult to ensure that the spindle nose of main shaft is injury-free, main shaft and Sealing junction exist weares and teares, and often needs to change, and cost is higher.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of wheel hub of corrosion resistant belt wheel hub sleeve is provided, effectively prevents spindle nose from contacting with etchant gas.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of wheel hub of corrosion resistant belt wheel hub sleeve, comprise wheel hub, described wheel hub is fixed on main shaft by spindle nose block and round nut, the front of described wheel hub is provided with cavity, described spindle nose block and described round nut are arranged in described cavity, described cavity, by pressing plate for sealing, arranges sealed department outside described wheel hub, is provided with wheel hub sleeve between described wheel hub and described sealed department.
As what optimize, be provided with rubber pad between described pressing plate and described cavity to seal the gap between described pressing plate and described cavity.
As what optimize, described rubber pad is ethylene-propylene-diene monomer rubber cushion
As what optimize, describedly take turns that hub sleeve is removably sheathed to be fixed on described wheel hub.
As what optimize, described sealed department is static element.
As what optimize, described pressing plate is stainless steel.
As what optimize, described material of taking turns hub sleeve is corrosion-resistant stainless steel.
The invention has the beneficial effects as follows:
The present invention is novel in design, and structure is simple, by arranging a cavity in wheel hub front, for holding spindle nose round nut when main shaft is connected with wheel hub, efficiently avoid the contact of spindle nose and etchant gas, ensures that blower fan volume normally runs;
And the present invention is by setting up wheel hub sleeve, prevents sealed department directly contact chronically with wheel hub and cause the wearing and tearing of sealed department and wheel hub, and causing often changing wheel hub, save cost, and it is more simple and convenient to change wheel hub sleeve.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 overall structure schematic diagram.
Number in the figure illustrates: 1, wheel hub, 2, sealed department, 3, wheel hub sleeve, 4, cavity, 5, rubber pad, 6, spindle nose block, 7, round nut, 8, pressing plate.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
With reference to shown in Fig. 1, a kind of wheel hub of corrosion resistant belt wheel hub sleeve, comprise wheel hub 1, be used for connecting main shaft and impeller, corrosion resistant stainless steel generally selected by described wheel hub 1, described wheel hub 1 is fixed on main shaft by spindle nose block 6 and round nut 7, the front of described wheel hub 1 is provided with cavity 4, described spindle nose block 6 is arranged in described cavity 4 with described round nut 7, because described main shaft, described round nut 7 and described axle sleeve block 6 are the manufactures of common material, do not possess decay resistance, so described cavity 4 is sealed by pressing plate 8, described pressing plate is stainless steel, corrosion-resistant gas and described wheel hub cavity 4 are completely cut off, protect the main shaft in described cavity 4, round nut 7 and axle sleeve block 6, ethylene-propylene-diene monomer rubber cushion 5 is also provided with to seal the gap between described pressing plate 8 and described cavity 4 between described pressing plate 8 and described cavity 4, described pressing plate 8 had both served the effect compressing described cavity 4, serve again the effect compressing described rubber pad 5, outside described wheel hub 1, sealed department 2 is set, described sealed department 2 selects resistant material, be generally stainless steel, effectively prevent Leakage Gas, be provided with between described wheel hub 1 and described sealed department 2 and take turns hub sleeve 3, corrosion resistant stainless steel selected by described hub sleeve 3 of taking turns, protect described wheel hub 1, can prevent from self from being corroded by corrosion-resistant gas, describedly take turns that hub sleeve 3 is removably sheathed to be fixed on described wheel hub 1, described wheel hub 1 closely coordinates with described hub sleeve 3 of taking turns, because described wheel hub 1 is revolving part, and described sealed department 2 is static element, therefore friction can be produced to described sealed department 2 when described wheel hub 1 constantly rotates, and long-term friction causes described wheel hub 1 and the contact surface of described sealed department 2 to wear and tear, affect tightness, described on described wheel hub 1 removably sheathed install wheel hub sleeve 3, described wheel hub 1 is prevented directly to be connected to produce with described sealed department 2 and to rub, cause parts damages, and described hub sleeve 3 of taking turns fluidly is arranged on described wheel hub 1, can change termly like this and describedly take turns hub sleeve 3, described wheel hub 1 cost is changed low than in the past, and change conveniently.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
