Abstract
The utility model discloses a belt pulley capable of performing heat radiation to the driving belt. One or more heat radiating blade is fixed on the outer surface of the belt pulley, and the blades of the heat radiating blade are radially arranged along the belt pulley. By adopting the structure, when working normally, the belt pulley drives the heat radiating blade to rotate simultaneously, which can intensify the air flow nearby the belt pulley, so as to bring away the heat produced by friction between the driving belt and the belt pulley, perform heat radiation to the belt pulley and the driving belt, and prolong the service life of the driving belt.
Description
Technical field
The utility model relates to a kind of belt transmission equipment, and definite saying so relates to a kind of belt pulley.
Background technique
In machinery, particularly on the transmission device such as motor or internal-combustion engine, a large amount of belt pulleys that all are to use carry out transmission, and the belt pulley easy processing, and cost is low, transmission is carried out in friction by belt and belt pulley groove face, when high speed rotating, the high-speed friction between drivign belt and the belt pulley can make the temperature of drivign belt raise rapidly, makes its paranormal serviceability temperature, the aging of belt of driving up shortens its working life.
The model utility content
Task of the present utility model is: a kind of belt pulley that can dispel the heat to drivign belt is provided, to reduce the temperature of drivign belt, prolongs drivign belt and be to use the life-span.
The technical solution of the utility model is: a kind of belt pulley, on the end face of the outside of described belt pulley, be fixed with one or more heat radiation fan blade, and the blade of this heat radiation fan blade is along the radially setting of belt pulley.
Described heat radiation fan blade extends the end face outer rim of this belt pulley on its length direction.
Two blades are set on the described heat radiation fan blade at least and are evenly distributed by circumference.
The blade of described heat radiation fan blade plane of living in and belt pulley end face are inclined to set, and the true dip direction unanimity of all blades.
The impeller that described radiator shutter is structure as a whole, this impeller is coaxial to be fixed on the side end face of belt pulley.
Adopt said structure, when proper functioning, belt pulley drives the heat radiation fan blade and rotates simultaneously, and the heat radiation fan blade can be strengthened near the air flows the belt pulley, drivign belt and the fricative heat of belt pulley are taken away so that belt pulley and drivign belt are dispelled the heat, prolonged the working life of drivign belt.

Embodiment
Embodiment one: as shown in Figure 1 and Figure 2, heat radiation fan blade 2 is fixedly mounted on the outer side surface of belt pulley by known technology, its heat radiation fan blade 2 is the monomer double blade structure, these two blades are 180 ° and are symmetrical arranged, and two radiator shutters 2 extend the end face outer rim of belt pulley 1 and perpendicular to the outer side surface of belt pulley 1 on its length direction.
Embodiment two: as shown in Figure 3, present embodiment two is that with embodiment one difference heat radiation fan blade 2 is three a blade monomer structures heat radiation fan blade.
Embodiment three: as shown in Figure 4, present embodiment three is that with embodiment one difference heat radiation fan blade 2 is three blade integrative-structure impellers.
Embodiment four: as shown in Figure 5, present embodiment four is that with embodiment two difference the blade plane of living in and belt pulley 1 end face of heat radiation fan blade 2 are inclined to set the true dip direction unanimity of all blades.
Embodiment five: as shown in Figure 6, present embodiment five is that with embodiment three difference heat radiation fan blade 2 is obliquely installed the true dip direction unanimity of all blades along the sense of rotation of belt pulley 1.
Be not limited to above-mentioned mode of execution in the utility model; those skilled in the art can expect the heat radiation fan blade of other shape or structure; though but do any variation in its profile or structure, every side at belt pulley is fixed with the heat radiation fan blade and all drops within the protection domain of the present utility model.
Claims (5)
1, a kind of belt pulley is characterized in that, is fixed with one or more heat radiation fan blade on the end face of the outside of described belt pulley, and the blade of this heat radiation fan blade is along the radially setting of belt pulley.
