Description
Technical field
The utility model relates to blower fan technical field, the draught fan impeller hub disk that specifically a kind of structure is simple, easy to use, durable.
Background technique
At present, conventional fan impeller is mainly provided with fan reel and impeller hub disk, the means of fixation of fan reel and impeller hub disk is riveted joint, adopt the reel weight of riveting method large, cause impeller overall weight large, in blower fan rotation process, consumed power is large, have a strong impact on the utilization efficiency of blower fan, and in riveting process, need the riveting equipment using specialty, at substantial manpower, material resources, cost is higher, the patent No. is the large high-speed centrifugal blower fan blade wheel of a kind of welding reel of 2012204124404, draught fan impeller hub disk and axle sleeve adopt welding manner, stiffening ring one end is welded on axle sleeve upper end, the other end is welded on impeller hub disk, added stiffening ring is frustum shape, structural instability, under running up, draught fan impeller intensity is low, very easily be damaged, when air intake, pressure is produced to impeller hub disk, wheel rotation produces resistance, and then power consumpiton increases.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides the draught fan impeller hub disk that a kind of structure is simple, easy to use, durable.
The utility model solves the technological scheme that its technical problem adopts:
A kind of draught fan impeller hub disk, be provided with impeller hub disk and axle sleeve, the lower end of axle sleeve is connected with impeller hub disk by welding, it is characterized in that being provided with supporting sleeve, supporting sleeve one end is welded on axle sleeve upper end, the supporting sleeve the other end is welded on impeller hub disk, supporting sleeve cross section is in the hyperbolic-type caved inward, air intake is more easily discharged, reduce air intake to the pressure of supporting sleeve, the tightness of protection axle sleeve and impeller hub disk, support arm is provided with inside supporting sleeve, support arm cross section is the bench-type of falling vertebra, support arm one end is welded on axle sleeve and impeller hub disk joint, the support arm the other end is welded in the cambered surface of supporting sleeve, for reinforcing supporting sleeve, the weight because of solid construction is avoided to add power consumption, add integrally-built steadiness simultaneously.
A kind of draught fan impeller hub disk described in the utility model, is characterized in that supporting sleeve has helical air guide channel in clockwise annular distribution, not only reduces air intake to the pressure of supporting sleeve, can also provide power, alleviate impeller negative pressure for impeller hub disk rotates.
The utility model, owing to adopting said structure, makes impeller overall structure alleviate, and reduces power consumpiton, and takes welded structure, decrease human and material resources, the advantage such as have that structure is simple, easy to use, expense is low and endurance is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of draught fan impeller hub disk, be provided with impeller hub disk 1 and axle sleeve 2, the lower end of axle sleeve 2 is connected with impeller hub disk 1 by welding, it is characterized in that being provided with supporting sleeve 3, supporting sleeve 3 one end is welded on axle sleeve 2 upper end, supporting sleeve 3 the other end is welded on impeller hub disk 1, supporting sleeve 3 cross section is in the hyperbolic-type caved inward, air intake is more easily discharged, reduce air intake to the pressure of supporting sleeve, the tightness of protection axle sleeve 2 and impeller hub disk 1, support arm 5 is provided with inside supporting sleeve 3, support arm 5 cross section is the bench-type of falling vertebra, support arm 5 one end is welded on axle sleeve 2 and impeller hub disk 1 joint, support arm 5 the other end is welded in the cambered surface of supporting sleeve 3, for reinforcing supporting sleeve 3, the weight because of solid construction is avoided to add power consumption, add integrally-built steadiness simultaneously, supporting sleeve 3 there is helical air guide channel 4 in clockwise annular distribution, not only reduce air intake to the pressure of supporting sleeve 3, power can also be provided for impeller hub disk 1 rotates, alleviate impeller negative pressure.
The utility model in use, because quality alleviates, accelerate the operating rate of blower fan, and under running up, when producing strong centrifugal force, vibration force and foreign impacts power, not easily produce the high risk phenomenon such as distortion, vibrations fracture, simultaneously, reduce air intake to the pressure of impeller hub disk, and utilize air intake to provide power for impeller hub disk, its Security performance is significantly improved.
The utility model, owing to adopting said structure, makes impeller overall structure alleviate, and reduces power consumpiton, and takes welded structure, decrease human and material resources, the advantage such as have that structure is simple, easy to use, expense is low and endurance is strong.
