Abstract
Blower impeller, mainly by wheel hub and a plurality of blades, the wheel hub center sets up the shaft hole, sets up the reinforcing plate between wheel hub's inner wall and the shaft hole, with wheel hub wall connection's root of blade setting and the unanimous cambered surface reinforcing plate of blade arc. The utility model discloses a set up the reinforcing plate and improved wheel hub operation structural stability between wheel hub's inner wall and shaft hole, guaranteed wheel hub's axial plane circular constant, set up the cambered surface reinforcing plate at the root of blade simultaneously, improved blade and wheel hub's joint strength greatly, have simple structure, the operation is stabilized and the high temperature resistance advantage.
Description
Technical field
The utility model is related to blower fan accessory technical field and in particular to a kind of draught fan impeller.
Background technology
Blower fan is the custom abbreviation to gas compression and gas conveying machinery, and usually said blower fan includes ventilation blower, drum
Blower fan, wind-driven generator.Gas compression and gas conveying machinery are that the mechanical energy rotating is converted to gas pressure energy and kinetic energy,
And the machinery that gas transferred out.Blower fan main structural components are impeller, casing, air inlet, support, motor, belt pulley, connection
Axial organ, muffler, driving member (bearing) etc..The impeller of blower fan is mainly made up of wheel hub and some blades at present, and impeller is integrally tied
Structure intensity is poor, and the wheel hub of the draught fan impeller especially working under hot environment is susceptible to deform, and leads to wheel hub axial plane circumference to become
Shape leads to unstable, air quantity reduction even stall of blowing, and blade is also susceptible to rupture with the junction of wheel hub, serious shadow
Ring the service life of draught fan impeller.
Utility model content
The utility model provides a kind of draught fan impeller, is held with the overall construction intensity difference wheel hub solving prior art presence
Easily deform and blade is connected the problem rupturing with wheel hub.
The utility model is mainly made up of wheel hub and some blades, and hub centre arranges axis hole, solves its technical problem institute
Employed technical scheme comprise that between the inwall of wheel hub and axis hole setting reinforcing plate, the root of blade setting being connected with hub outer wall and
The consistent cambered surface reinforcing plate of blade arc.
Above-mentioned axis hole root arranges reinforcement.
It is stable that the utility model improves wheel hub operating structure by setting reinforcing plate between the inwall and axis hole of wheel hub
Property it is ensured that the axial plane pi of wheel hub, cambered surface reinforcing plate is set in root of blade simultaneously, substantially increases blade and wheel hub
Bonding strength, has simple, the stable and resistant to elevated temperatures advantage of structure.
Brief description
With reference to the accompanying drawings and examples the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic rear view of the utility model blade；
Fig. 3 is the schematic rear view of the utility model wheel hub；
Fig. 4 is the schematic cross-section of the utility model wheel hub.
In figure 1 blade, 2 cambered surface reinforcing plates, 3 wheel hubs, 4 axis holes, 5 reinforcing plates, 6 reinforcements.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of draught fan impeller, is mainly made up of wheel hub 3 and some blades 1, wheel hub 3
Centrally disposed axis hole 4, arranges reinforcing plate 5 between the inwall of wheel hub 3 and axis hole 4, blade 1 root being connected with wheel hub 3 outer wall is set
Put the cambered surface reinforcing plate 2 consistent with blade 1 arc, axis hole 4 root arranges reinforcement 6.
It is stable that the utility model improves wheel hub operating structure by setting reinforcing plate between the inwall and axis hole of wheel hub
Property it is ensured that the axial plane pi of wheel hub, cambered surface reinforcing plate is set in root of blade simultaneously, substantially increases blade and wheel hub
Bonding strength, has simple, the stable and resistant to elevated temperatures advantage of structure.
