Abstract
The utility model relates to a belt transmission equipment specifically provides a belt pulley, including the wheel body, all locate the race of wheel body surface and set up the wheel shaft hole in the center of wheel body, the shaft is downthehole installs and takes turns shaft hole phase -match and detachable axle sleeve, shaft hole and keyway have been seted up in the axle sleeve, axle sleeve and the wheel shaft hole department of meeting are provided with the location pinhole, the location pinhole is including setting up the half first pinhole and second half pinhole of setting on round shaft hole on the axle sleeve, be provided with the louvre on the wheel body between race and the wheel shaft hole. The utility model provides a belt pulley, simple structure, the antiskid is effectual, when wearing and tearing appearing, need more not change whole belt pulley, has reduced use cost.
Description
Technical field
The utility model relates to a kind of belt drive device, is specifically related to a kind of belt pulley.
Background technique
Belt pulley belongs to hub class part, and general relative size 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.In the process used, belt pulley is connected with the output shaft of motor, drives pulley rotation by motor output shaft, thus realizes the transmission to power.In long using process, can wear and tear in the joint of the output shaft of belt pulley and motor, reduce the transmission efficiency to motor power, affects the working efficiency of whole machine, at this moment just needs to change belt pulley.Belt pulley is mostly integral type, must change whole belt pulley, add user cost during replacing.
In addition, the structure of pulley drive is simple, easy to adjust; But be pulley drive flexible slip and the skidding of bel-drivenn shortcoming, causes belt pulley to be easy to heating, and causes belt easily aging, so the life-span of the drivign belt of belt pulley is shorter.
Model utility content
The purpose of this utility model is the defect overcoming above-mentioned prior art, provides that a kind of structure is simple, a kind of belt pulley of rapid heat dissipation, long service life.
For this reason, the utility model provides a kind of belt pulley, comprise wheel body, be all located at the axle hole of the belt grooves of taking turns external surface and the central position being arranged on wheel body, be provided with in described axle hole and match and dismountable axle sleeve with axle hole, axis hole and keyway is offered in described axle sleeve, described axle sleeve and axle hole connecting part are provided with positioning pin hole, and described positioning pin hole comprises the first half pin-and-holes that are arranged on axle sleeve and the second half pin-and-holes be arranged on axle hole; Wheel body between described belt grooves and axle hole is provided with radiation hole.
As preferably, described positioning pin hole has three and is uniformly distributed.
As preferably, described radiation hole has three and along the distribution of axle hole circumference.
As structural improvement, the inwall of described belt grooves is provided with hatching knurling.Belt is not easy the phenomenon occurring skidding in the belt grooves with hatching knurling wall, and structure is simple, good antiskid effect.
The beneficial effects of the utility model: this belt pulley that the utility model provides, add radiation hole, when belt pulley is worked and the heat that produces of belt friction distribute rapidly, effectively reduce the temperature of belt pulley, thus also reduce the temperature of belt, reach the object extending belt life, ensure transmission effect.Belt is not easy the phenomenon occurring skidding in the belt grooves of belt pulley with hatching knurling wall, and structure is simple, good antiskid effect.In the long-time using process of belt pulley, do not need whole belt pulley to replace, reduce user cost.
Accompanying drawing explanation
Fig. 1 is decomposing schematic representation of the present utility model.
Description of reference numerals: 1, wheel body; 2, belt grooves; 3, axle hole; 4, the second half pin-and-holes; 5, radiation hole; 6, axis hole; 7, axle sleeve; 8, keyway; 9, the first half pin-and-holes.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
Embodiment:
Present embodiments provide a kind of belt pulley, as shown in Figure 1, comprise wheel body 1, be all located at the belt grooves 2 of wheel body 1 outer surface and be arranged on the axle hole 3 of central position of wheel body 1, be provided with in described axle hole 3 and match and dismountable axle sleeve 7 with axle hole 3, axis hole 6 and keyway 8 is offered in described axle sleeve 7, described axle sleeve 7 and axle hole 3 connecting part are provided with positioning pin hole, and described positioning pin hole comprises the first half pin-and-holes 9 that are arranged on axle sleeve 7 and the second half pin-and-holes 4 be arranged on axle hole 3; Described positioning pin hole has three and is uniformly distributed.By positioning pin hole, axle sleeve 7 is fixed in axis hole 6.In long using process, axle sleeve 7 can wear and tear with the joint of the output shaft of motor, only needs to change axle sleeve 7, and does not need whole belt pulley to replace, reduce user cost during replacing; Wheel body 1 between described belt grooves 2 and axle hole 3 is provided with radiation hole 5.Described radiation hole 5 has three and distributes along axle hole 6 circumference.Add radiation hole 5, when belt pulley is worked and the heat that produces of belt friction distribute rapidly, effectively reduce the temperature of belt pulley, thus also reduce the temperature of belt, reach the object extending belt life, ensure transmission effect.
The inwall of described belt grooves 2 is provided with hatching knurling.Belt is not easy the phenomenon occurring skidding in the belt grooves 2 of hatching knurling wall, and structure is simple, good antiskid effect.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection scope of the present invention with the same or analogous design of the utility model.
