Abstract
A kind of belt pulley, comprises axle hole, outer rim, the both sides of described outer rim all axially extends the back-up ring being provided with certain altitude, the circumference of described back-up ring is laid with a plurality of vent hole; Evenly be provided with a plurality of arc-shaped webs between outside described axle hole and inside outer rim, the neutral position of described arc-shaped webs is provided with circular heat dissipating ring, and described heat dissipating ring is provided with a plurality of Heat sink vertically arranged with heat dissipating ring between outside and arc-shaped webs.The utility model structure is simple, reasonable in design, when belt pulley High Rotation Speed drives belt running, fricative heat can well be dispelled the heat by heat dissipating ring and Heat sink, belt pulley self rotates just can produce larger wind-force, the heat dissipation rate of heat dissipating ring and Heat sink is accelerated, the slippage of belt can also be prevented simultaneously.
Description
Technical field
The utility model relates to field of engineering technology, particularly relates to a kind of belt pulley.
Background technique
The general relative size of belt pulley is larger, generally to cast, to be forged to master in manufacturing process.Belt pulley is mainly used in the occasion of Long Distant Transmit power, such as the output of miniature diesel mechanomotive force, agricultural vehicle, tractor, automobile, mining machinery, machining equipment, textile manufacturing machine, package packing machine, lathe, forging bed, the transmission of some fraction horsepower motorcycle powers, the transmission of farm machinery power, air compressor, retarder, speed reducer, generator, Gins etc.
The deficiency of existing belt pulley is, axial displacement may occur, cause slippage time serious between belt and belt pulley, and the normal operation of impact machinery, brings unnecessary loss to production.Relative sliding between belt pulley and belt, produces larger frictional heat, affects the performance of belt.In transmission process, the frictional force bottom belt pulley and between belt is relied on to carry out transmission, these frictions can produce very large heat, these heat accumulations are on belt pulley or belt, be difficult to leave, temperature when belt is worked improves greatly, and accelerate the aging speed of belt, working life greatly reduces.The sink of what belt pulley on the market had be provided with fan and so on, this result is complicated, and easy damage adds manufacture cost simultaneously, also impracticable.
Therefore, how solving the problem, is the content that those skilled in the art will study.
Model utility content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of belt pulley of perfect heat-dissipating, thus improves the working life of belt.
The utility model is achieved through the following technical solutions: a kind of belt pulley, comprises axle hole, outer rim, the both sides of described outer rim all axially extends the back-up ring being provided with certain altitude, the circumference of described back-up ring is laid with a plurality of vent hole; Evenly be provided with a plurality of arc-shaped webs between outside described axle hole and inside outer rim, the neutral position of described arc-shaped webs is provided with circular heat dissipating ring, and described heat dissipating ring is provided with a plurality of Heat sink vertically arranged with heat dissipating ring between outside and arc-shaped webs.
In such scheme, related content is explained as follows:
1, in such scheme, described back-up ring welds with outer rim or one-body molded;
2, in such scheme, described vent hole is inclined vent holes, and described vent hole tilts towards the direction of pulley rotation from inside to outside;
3, in such scheme, the outer openings of described vent hole is greater than interior side opening;
4, in such scheme, the rectangular structure of described Heat sink.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model structure is simple, reasonable in design, when belt pulley High Rotation Speed drives belt running, fricative heat can well be dispelled the heat by heat dissipating ring and Heat sink, belt pulley self rotates just can produce larger wind-force, the heat dissipation rate of heat dissipating ring and Heat sink is accelerated, the slippage of belt can also be prevented simultaneously;
Uniform in the circumference of 2, the back-up ring of the utility model on outer rim both sides a plurality of vent hole is set, when belt pulley High Rotation Speed, wind is blown into by vent hole in the cell body that formed by two back-up rings and outer rim, cools drivign belt, reaches the effect of cooling belt.Along with the rotation of belt pulley, these heats are distributed, thus reduce the operating temperature of drivign belt, extend the working life of drivign belt.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of belt pulley, comprises axle hole 1, outer rim 2, and wherein axle hole 1 coordinates to be connected with wheel shaft by the keyway on it and key, the both sides of described outer rim 2 all axially extend the back-up ring 3 being provided with certain altitude, the circumference of described back-up ring 3 is laid with a plurality of vent hole 7.Described back-up ring 3 welds with outer rim 2 or one-body molded, can effectively prevent belt from operation process, slippage occurring like this, and the height of back-up ring 3 is at least 10mm, several arc-shaped webs 4 are evenly provided with between outside described axle hole 1 and inside outer rim 2, wherein arc-shaped webs 4 and axle hole 1, outer rim 2 is welded to connect, and arc-shaped webs 4 can increase the area of contact of belt pulley and air, improve radiating efficiency, the neutral position of described arc-shaped webs 4 is provided with circular heat dissipating ring 5, described heat dissipating ring 5 is provided with several and the vertically arranged Heat sink 6 of heat dissipating ring 5 between outside and arc-shaped webs 4, the rectangular structure of described Heat sink 6, when belt pulley High Rotation Speed drives belt running, fricative heat can well be dispelled the heat by heat dissipating ring 5 and Heat sink 6, belt pulley self rotates just can produce larger wind-force, heat dissipating ring 5 is accelerated with the heat dissipation rate of Heat sink 6.
Described vent hole 7 is inclined vent holes, and described vent hole 7 tilts towards the direction of pulley rotation from inside to outside.The outer openings of described vent hole 7 is greater than interior side opening.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
