Abstract
The invention discloses a kind of belt pulley, including wheel hub and wheel rim, wheel hub is connected with wheel rim by disc, multiple belt grooves are provided with wheel rim, multiple belt grooves are equally arranged, web width is less than the groove width of the belt grooves, the first heat emission hole is equipped with the side wall of belt grooves, the bottom of belt grooves is equipped with the second heat emission hole, and the first heat emission hole and the second heat emission hole are through hole, and the first heat emission hole is scallop hole.Heat produced by the present invention timely and effectively can rub belt with belt pulley is distributed, and prevents that temperature when belt works is too high, effectively slow down the aging speed of belt, increases belt service life.
Description
Technical field
The present invention relates to drive technology field, and in particular to a kind of 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
The technical problem to be solved in the present invention is to provide a kind of belt pulley, timely and effectively belt can be rubbed with belt pulley
Heat produced by wiping 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 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 on 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 invention has the advantages that：The belt pulley of the present invention, timely and effectively can rub belt with belt pulley
Heat produced by wiping is distributed, and is prevented that temperature when belt works is too high, effectively be slow down the aging speed of belt, is increased
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；
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 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 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, which is less than on the groove width of belt grooves 13, the side wall of belt grooves 13, is equipped with the first heat emission hole 11, 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.Being designed to of first heat emission hole 11 and the second heat emission hole 12 rubs belt and belt pulley institute during belt transmission
The heat of generation is distributed 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 processing.
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, 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
Protection domain within.Protection scope of the present invention is defined by claims.
