Part clamping is connected, and locating effect is more preferable.
In a kind of above-mentioned belt wind wheel structure, the inner cavity of the through-hole is in the small wedge shape of outer imperial palace.It is logical by setting
Imperial palace is small outside the inner cavity in hole, and the connector being arranged in this way in through-hole is hidden in through-hole close to one end of belt pulley and can also be realized
Clamping, it is not necessary to installation space is reserved between impeller and belt pulley, structure is compacter.
In a kind of above-mentioned belt wind wheel structure, the consistency of thickness of the thickness of the gasket and the impeller.Impeller
Size is greater than gasket, by the thickness of gasket and the consistency of thickness of impeller, can utilize the remaining sheet fabrication pad of Impeller Machining
Piece saves production cost.
Compared with prior art, it is as follows the advantages of the utility model：
1st, this belt wind wheel structure is at the middle part of impeller by setting the lug boss being recessed to belt pulley, and make lug boss with
The side wall of belt pulley leans, and lug boss can fill the space of belt pulley side, and motor is convenient in the space on the inside of lug boss
Arrangement, make overall structure compacter, improve space utilization effect.
2nd, this belt wind wheel structure by lug boss inner coaxial set plate-like gasket, increase middle part counterweight and
The contact area of structure and motor shaft improves the job stability of belt wind wheel structure.

Specific embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
If Fig. 1-3 shows, this belt wind wheel structure includes belt pulley 1 and impeller 2, and belt pulley 1 and impeller 2 are coaxially arranged, leaf
The middle part of wheel 2 forms lug boss 21 towards the recess of belt pulley 1, and the side wall of the lateral surface and belt pulley 1 of lug boss 21 leans.Skin
Belt wheel 1 and impeller 2 is coaxially arranged and motor shaft connection, the rotation of motor impeller 2 provides blowing for motor and radiates, while motor
The rotation of belt pulley 1 is driven so as to which belt drives subsequent parts.The belt pulley 1 of existing small size is mostly that platy structure has its side wall
There is cavity, by setting the lug boss 21 being recessed to belt pulley 1 at the middle part of impeller 2, and make the side of lug boss 21 and belt pulley 1
