Description
Technical field
The utility model is related to blower fan, specifically a kind of compact blower fan structure.
Background technology
The development of industrial ventilation machine, it is increasingly extensive in different industries application, for different use environments, to blower fan space
Occupancy proposes new requirement, particularly when blower fan as the auxiliary equipment of large scale equipment in use, needing assembling at this
The a certain ad-hoc location of equipment, leaves the installing space of blower fan for by a definite limitation, it is desirable to which blower fan is ensureing enough Wind Volumes, wind
Taken up space less as far as possible in the case of pressure, to reduce equipment overall volume.Traditional general blower fan structure form is used this
In the case of, using being very limited.
Utility model content
The purpose of this utility model is to provide a kind of compact blower fan structure, effectively meets the occupancy that reduces space and narrow
Narrow space particular/special requirement.
In order to reach above-mentioned purpose, the utility model employs following technical scheme, a kind of compact blower fan structure, including
Casing, impeller, transmission mechanism, the impeller are arranged on transmission mechanism end, and impeller is entirely located in casing internal, driver simultaneously
Structure is fixed on casing, and the transmission mechanism includes main shaft and the bearing and bearing block that are enclosed on main shaft, wherein the one of main shaft
End connection impeller, other end connection belt pulley, the impeller is arranged on main shaft by dish-shaped reel, inside the dish-shaped reel
For hollow cavity, inside the dish-shaped reel of bearing block partial insertion.
Suit fixed disk outside the bearing block.
The fixed disk is connected with support plate, and the support plate is welded on casing.
The casing includes front side board, back side panel, spiral case, and the spiral case is connected between front side board, back side panel.
The impeller includes shroud, blade, the hub disk welded together, and the hub disk is riveted on dish-shaped reel.
Compared to prior art, the utility model has the advantages that：
The utility model is improved by the structure to fan part, makes blower fan overall structure compacter.Reel is changed to dish
Shape leaves bearing block to impeller direction insertion space, and the bracing ring of bearing block and welding and casing is directly connected to, and makes casing and master
Sealing effectiveness is more preferable between axle.The simple modifications of transmission group internal structure solve the drawbacks of original structure is present.This practicality is new
Type is rational in infrastructure, safe and reliable, easy manufacture, cost are low, can be widely applied to industry, agricultural machinery and environmental protection industry (epi), effectively meets and subtract
The occupancy and narrow space particular/special requirement in small space.New application scenario, which is added, for Fan Product requires that application prospect is very
It is wide.

With purposes of discussion, not for being any limitation as to the utility model.
As shown in figure 1, a kind of compact blower fan structure, including casing 5, impeller 11, transmission mechanism, the impeller is arranged on
Transmission mechanism end, impeller is entirely located in casing internal simultaneously, and transmission mechanism is fixed on casing, and the transmission mechanism includes master
Axle 1 and the bearing being enclosed on main shaft and bearing block 9, wherein one end connection impeller 11 of main shaft, other end connection belt pulley 10,
The impeller is arranged on main shaft by dish-shaped reel 2, is hollow cavity inside the dish-shaped reel, dish is inserted for bearing block
Inside reel.Suit fixed disk 8 outside the bearing block.The fixed disk is connected with support plate 7, the support plate welding
On casing.The casing includes front side board, back side panel, spiral case, and the spiral case is connected between front side board, back side panel.It is described
Impeller includes shroud, blade, the hub disk welded together, and the hub disk is riveted on dish-shaped reel.
Impeller 11 is, by shroud 13, blade 12, the soldering of hub disk 14 one, to be formed with rivet with the dish-shaped riveted of reel 2, and protect
Positive impeller sets running accuracy and requirement for dynamic balance, rotation is connected with main shaft by key.
Casing 5 be by forward and backward side plate 3,6, the soldering of spiral case 4 and be integrated with the soldering of base 15.
Transmission component is made up of bearing block 9, bearing, main shaft 1, belt pulley 10, and fixed disk 8 is fixed in outside bearing block 9,
Fixed disk 8 is bolted with bracing ring 7, and bracing ring soldering forms one on the back side panel 6 of casing.Power source drives
Belt pulley, main shaft, impeller assembly rotate and normal work.
Dish-shaped hollow cavity is made so that bearing block is inserted inside dish reel 2 in draught fan impeller dish reel 2, shortens axially
Metric space.Transmission component is that the fixed disk 8 on bearing block 9 is supported, and axial distance position can be set according to actual condition.Machine
The back side panel design bracing ring of shell, is bolted the fixed disk on bearing block, to support transmission component and impeller assembly shape
Into the integration of rotor set system.Bearing block is fixed by bolts on bracing ring, and such casing forms totally-enclosed form with bearing block.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the scope of the claims of the present utility model, its
He uses the equivalence changes of the utility model patent spirit, all should all belong to the scope of the claims of the present utility model.
