Description
Technical field
It the utility model is related to drive technology field, and in particular to a kind of belt pulley.
Background technology
Belt transmission is widely used transmission system in plant equipment, during existing belt transmission, is relied 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 greatly improves, and adds
The fast aging speed of belt, belt service life greatly shorten.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of belt pulley, can be timely and effectively by belt and belt
Heat caused by wheel friction distributes, and prevents that temperature when belt works is too high, effectively slow down the aging speed of belt.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is provided is as follows：
A kind of belt pulley, including wheel hub and wheel rim, the wheel hub are connected with wheel rim by disc, are set on the wheel rim
There are multiple belt grooves, the multiple belt grooves are equally arranged, the web width is less than the groove width of the belt grooves, described
Be equipped with the first heat emission hole in the side wall of belt grooves, the bottoms of the belt grooves is equipped with the second heat emission hole, the first heat emission hole and
Second heat emission hole is through hole, and first heat emission hole is scallop hole.
Circumference of first heat emission hole along the wheel rim is in be evenly arranged.
The width of the disc is less than the axial length of the wheel hub.
Second heat emission hole is circular hole.
The disc is in be arranged circumferentially.
The disc is at least three.
The belt grooves are dovetail groove or rectangular channel.
The disc is in sector.
Keyway is provided with the wheel hub.
The utility model has the advantages that：Belt pulley of the present utility model, can timely and effectively by belt with
Heat caused by belt pulley friction distributes, and prevents that temperature when belt works is too high, effectively slow down the aging of belt
Speed, increase belt service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the cross section structure diagram at A-A in Fig. 1；
In figure：1. wheel rim, the 11, first heat emission hole, 12. second heat emission holes, 13. belt grooves, 2. disc, 3. wheel hubs, 31. axles
Hole, 32. keyways.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As depicted in figs. 1 and 2, a kind of belt pulley, including wheel hub 3 and wheel rim 1, wheel hub 3 are connected with wheel rim 1 by disc 2
Connect, multiple belt grooves 13 are provided with wheel rim 1, belt grooves 13 are used to install belt, and multiple belt grooves 13 are equally arranged, spoke
The width of plate 2 is H, and H is less than the groove width of belt grooves 13, the first heat emission hole 11 is equipped with the side wall of belt grooves 13, belt grooves 13
Bottom is equipped with the second heat emission hole 12, and the first heat emission hole 11 and the second heat emission hole 12 are through hole, and the first heat emission hole 11 is sector
Hole.First heat emission hole 11 and the second heat emission hole 12 are designed to that belt and belt pulley rub institute during belt transmission
Caused heat distributes in time, prevents that temperature when belt works is too high, effectively slow down the aging speed of belt, increase
Belt service life.
Wherein, wheel hub 3, wheel rim 1 and disc 2 are formed in one.
Further, circumference of first heat emission hole 11 along wheel rim 1 is in being evenly arranged, to play more preferable radiating effect.
Further, the width of disc 2 is less than the axial length of wheel hub 3, further to mitigate belt pulley overall weight.
Further, the second heat emission hole is circular hole, is easy to process.
Further, disc 2 is in being arranged circumferentially, and disc 2 is circumferentially setting at least to three, to cause disc 2
It is more uniformly stressed.
Further, belt grooves 13 are dovetail groove or rectangular channel.
Further, disc 2 is in sector.
Wherein, axis hole 31 is set in wheel hub 3, keyway 32 is provided with the inwall of axis hole 31, to be engaged with axle.
Embodiment described above is only the preferred embodiment to absolutely prove the utility model and being lifted, the utility model
Protection domain not limited to this.The equivalent substitute or change that those skilled in the art are made on the basis of the utility model
Change, within the scope of protection of the utility model.The scope of protection of the utility model is defined by claims.
