Description
Technical field
The present invention relates to drive technology field, and in particular to a kind of heat radiation belt pulley.
Background technology
During belt transmission is widely used transmission system in plant equipment, existing belt transmission, rely primarily on
Frictional force between belt pulley bottom or side and belt is driven, and these frictions can produce very big heat, heat master
It is gathered in belt grooves and belt, is difficult to disperse in the case of drawing badly, temperature when making the belt work is greatly improved, plus
The fast aging speed of belt, belt service life is greatly shortened.
The content of the invention
, can be timely and effectively by belt and belt the technical problem to be solved in the present invention is to provide a kind of heat radiation belt pulley
Heat produced by taking turns friction is distributed, and is prevented that temperature when belt works is too high, effectively be slow down the aging speed of belt.
In order to solve the above-mentioned technical problem, the technical scheme that the present invention is provided is as follows：
A kind of heat radiation belt pulley, including wheel hub and wheel rim, the wheel hub are connected with wheel rim by disc, on the wheel rim
Multiple belt grooves are provided with, the multiple belt grooves are equally arranged, the bottom of the belt grooves is equipped with the first air vent,
The wheel rim bottom is additionally provided with the second air vent, and the second air vent is along the axially arranged through hole of the wheel rim, the first ventilation
The one end in hole is connected with second air vent, and the other end of first air vent is disposed as flare openings.
The two ends of second air vent are also configured as flare openings.
Second air vent is equally arranged along the circumference of the wheel rim.
First air vent is circular port or rectangular opening.
Second air vent is circular port or rectangular opening.
Circular groove is provided with the disc, the circular groove is along wheel hub axially through the disc.
The disc is in be arranged circumferentially.
The belt grooves are dovetail groove or rectangular channel.
The disc is in sector.
Keyway is provided with the wheel hub.
The invention has the advantages that：The heat radiation belt pulley of the present invention, can be timely and effectively by belt and belt
Heat produced by taking turns friction is distributed, and is prevented that temperature when belt works is too high, effectively be slow down the aging speed of belt,
Increase belt service life.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the cross section structure diagram at A-A in Fig. 1；
Fig. 3 is the partial enlargement structural representation at B in Fig. 2；
In figure：1. wheel rim, the 11, second air vent, 12. first air vents, 121. flare openings, 13. belt grooves, 2. spokes
Plate, 21. circular grooves, 3. wheel hubs, 31. axis holes, 32. keyways.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be with
More fully understand the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As depicted in figs. 1 and 2, a kind of heat radiation belt pulley, including wheel hub 3 and wheel rim 1, wheel hub 3 and wheel rim 1 pass through disc 2
It is connected, is provided with multiple belt grooves 13 on wheel rim 1, belt grooves 13 is used to installing belt, multiple belt grooves 13 equally cloth
Put, the bottom of belt grooves 13 is equipped with the first air vent 12, and the bottom of wheel rim 1 is additionally provided with the second air vent 11, the second air vent
11 be that one end of first air vent 12 is connected with the second air vent 11 along the axially arranged through hole of wheel rim 1, such as Fig. 2 and Fig. 3
Shown, the other end of the first air vent 12 is disposed as flare openings 121.Flare openings 121 can preferably guide heat
Amount enters the first air vent 12, or the air-flow come out from the first air vent 12 is preferably distributed into belt grooves 13.First leads to
The design of the air vent 11 of air holes 12 and second, heat produced by timely and effectively belt and belt pulley can rub is from second
Distributed in air vent 11, prevent that temperature when belt works is too high, while also enabling outside air-flow logical from second
Air holes 11 enters the first air vent 12, so that temperature when effectively reduction belt works, slow down the aging speed of belt, increases
Belt service life.
Wherein, the two ends of the second air vent 11 are also configured as flare openings, preferably to ensure result of ventilating heat dissipation.
Wherein, wheel hub 3, wheel rim 1 and disc 2 are formed in one.
Further, the second air vent 11 is equally arranged along the circumference of wheel rim 1, to increase draught area, more
Radiate evenly.
Further, the first air vent 12 is circular port or rectangular opening.
Further, the second air vent 11 is circular port or rectangular opening.
Further, it is respectively provided with disc 2 by there is circular groove 21, circular groove 21 is along wheel hub 3 axially through disc 2, one side
The overall weight of belt pulley can be mitigated, certain thermolysis is on the other hand also functioned to.
Further, disc is in being arranged circumferentially, to cause being more uniformly stressed for disc 2.
Further, belt grooves are dovetail groove or rectangular channel.
Further, disc is in sector.
Wherein, set in wheel hub 3 on axis hole 31, the inwall of axis hole 31 and be provided with keyway 32, to be engaged with axle.
Embodiment described above is only the preferred embodiment to absolutely prove the present invention and being lifted, protection model of the invention
Enclose not limited to this.Equivalent substitute or conversion that those skilled in the art are made on the basis of the present invention, in the present invention
