Abstract
The utility model relates to a reinforced fan impeller comprising a wheel hub and blades which are arranged on the wheel hub, wherein the wheel hub is provided with an axial hole which is in driving fit with a drive shaft, the internal circle of the axial hole is fixedly provided with a reinforcing layer, and the material strength and durability of the reinforcing layer both are larger than those of the wheel hub. According to the reinforcing fan impeller disclosed by the utility model, the strength of a part matching the impeller and the transmission shaft is increased, deformation of the wheel hub caused by poor light metal durability and extrusion resistance after a fan runs for a long period is avoided, the service life of a fan is prolonged, the use cost is reduced, and safety accidents are avoided.
Description
Technical field
The utility model relates to a kind of ventilation cooling equipment annex, particularly a kind of blast fan that this accessory drive position is strengthened.
Background technique
Fan is as ventilation commonly used cooling equipment alive, and more general is applied.Fan generally comprises support, impeller and is used to drive the also power equipment of wheel rotation; Impeller is generally formed by wheel hub and the blade that is arranged on the wheel hub.Wheel hub generally cooperates with the rotary output axis of power equipment, reaches driven purpose.
Fan generally can have impact force when starting, perhaps, in normal transmission process, the matching part of axle and wheel hub and axle can bear the high fan of the big rotating speed of bigger moment of torsion, particularly power, and this moment of torsion is bigger.Wheel hub extrusion-deformation or heel and toe wear can occur with the installation position of axle in bearing above-mentioned moment of torsion process.Particularly along with development of science and technology, equipment trends towards the lightweight development, and blast fan generally adopts plastics (small-power) or light metal, is beneficial to the saving driving source; But the wear resistance and the crush resistance of light metal (such as aluminum alloy) are relatively poor, can cause the distortion of wheel hub behind the fan long-term operation; Can't continue to use, make whole impeller scrap, cause the wind electric fan to damage easily; Influence the normal operation of fan, even influence the working life of fan, increase financial cost; Also increase the difficulty of maintenance,, also security incident can take place for powerful fan.
Therefore; Need improve existing fan, increase the intensity at the position that cooperates between impeller and the transmission shaft, avoid owing to the distortion that can cause wheel hub behind light metal wear resistance and the relatively poor fan long-term operation that causes of crush resistance; Prolong the working life of fan; Increase the service life, reduce user cost, avoid the generation of security incident.
The model utility content
In view of this; The axis hole of the utility model is provided with iron cover electric fan, increases the intensity at the position that cooperates between impeller and the transmission shaft, avoids owing to the distortion that can cause wheel hub behind light metal wear resistance and the relatively poor fan long-term operation that causes of crush resistance; Prolong the working life of fan; Increase the service life, reduce user cost, avoid the generation of security incident.
The axis hole of the utility model is provided with iron cover electric fan; Comprise wheel hub and be arranged on the blade on the wheel hub; Said wheel hub is provided with and is used for the axis hole that cooperates with the live axle transmission, and coaxial Material Strength and the wear resistance of being fixed with of circle is all greater than the enhancement layer of hub material in the said axis hole.
Further, said enhancement layer takes shape in circle in the axis hole through castingin;
Further, said wheel hub is an aluminum alloy material, and enhancement layer is a spheroidal graphite cast iron;
Further, said enhancement layer is the bush structure of castingin moulding.
The beneficial effect of the utility model: the axis hole of the utility model is provided with iron cover electric fan, and circle is provided with enhancement layer in the wheel hub of blast fan, and the hardness of this enhancement layer and wear resistance are all greater than wheel hub; The driving force of transmission shaft reaches impeller through enhancement layer, thereby for impeller, increases the power transmission area; Pressure-bearing, to hold the mill parts be enhancement layer, increases the intensity at the position that cooperates between impeller and the transmission shaft, avoids owing to the distortion that can cause wheel hub behind light metal wear resistance and the relatively poor fan long-term operation that causes of crush resistance; Prolong the working life of fan; Increase the service life, reduce user cost, avoid the generation of security incident.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Embodiment
Fig. 1 is the structural representation of the utility model.As shown in the figure: the axis hole of present embodiment is provided with iron cover electric fan; Comprise wheel hub 1 and be arranged on the blade 11 on the wheel hub; Said wheel hub 1 is provided with and is used for the axis hole that cooperates with the live axle transmission; Coaxial Material Strength and the wear resistance of being fixed with of circle is all greater than the enhancement layer of wheel hub 1 material in the said axis hole; Wherein wheel hub 1 can also can be other macromolecular materials for light alloy, and enhancement layer 2 can be cast iron (spheroidal graphite cast iron etc.) or steel etc., also can be to strengthen copper sheathing (adding enhanced granule such as silica flour in the copper).
In the present embodiment, said enhancement layer 2 takes shape in the axis hole circle through castingin, and is simple in structure, realizes easily, can increase wheel hub simultaneously vertically or intensity radially, guarantees security of operation.
In the present embodiment, said wheel hub 1 is an aluminum alloy material, and enhancement layer 2 is a spheroidal graphite cast iron, is guaranteeing to gain in strength the saving driving source under the light-weighted prerequisite.
In the present embodiment, said enhancement layer 2 is the bush structure of castingin moulding, and is simple in structure, well arranged, the recyclable utilization of impeller.
Explanation is at last; Above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technological scheme of the utility model; And not breaking away from the aim and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
