Description
Technical field
The utility model relates to a kind of novel small belt pulley, belongs to metal processing sectors.
Background technique
Belt pulley, belong to hub class part, general relative size is larger, generally to cast, to be forged to master in manufacturing process.What stock size was larger is designed to the method using casting, and material is all generally cast iron (castability is better), seldom uses cast steel (castability of steel is not good); Stock size is less, can be designed as forging, and material is steel.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.Existing belt pulley solid wheel heavier-weight, hollow wheels intensity is low, and working life is short, have impact on production application.
Model utility content
For the deficiency that prior art exists, technical problem to be solved in the utility model is, provide a kind of novel small belt pulley, lightweight, intensity is high.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is, a kind of novel small belt pulley, and comprise middle part friction ring, the two ends of middle part friction ring are provided with little support ring and large support ring; Described large support ring comprises inner rim and outer rim, is provided with some support bars between inner rim and outer rim; Described inner rim comprises a torque drive groove, and torque drive groove is provided with columniform axis hole; Be provided with transmission shaft in described axis hole, transmission shaft is through middle part friction ring, little support ring and large support ring; The circular edge of described large support ring is provided with two groups of belt card sets, belt card sets comprises two opposed belt cards, and two groups of belt card sets are that cross is arranged; The joint of described little support ring and large support ring and middle part friction ring is respectively arranged with large belt buffer part and the belt lace buffer part of taper, and the tapering of large belt buffer part is less than the tapering of belt lace buffer part, and tapering difference is 0.5-1.
Optimize, above-mentioned novel small belt pulley, the circular edge of described little support ring is provided with one group of belt card sets.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.Thrown away by little support ring and large support ring restriction belt, use safety, reliable transmission.Preventing belt from throwing away further by arranging belt card sets on little support ring and large support ring, improving Security.Little support ring and large support ring are hollow structure, and inside arranges support bar, improve its intensity, ensure that overall transmission intensity and working life, and reduce its weight, decrease energy loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of Fig. 1;
In figure: 1 be middle part friction ring, 2 be little support ring, 3 be large support ring, 4 be support bar, 5 be torque drive groove, 6 for belt card.
Embodiment
Technical characterstic of the present invention is set forth further below in conjunction with accompanying drawing and specific embodiment.
Embodiment 1
The utility model is a kind of novel small belt pulley, and comprise middle part friction ring, the two ends of middle part friction ring are provided with little support ring and large support ring; Described large support ring comprises inner rim and outer rim, is provided with some support bars between inner rim and outer rim; Described inner rim comprises a torque drive groove, and torque drive groove is provided with columniform axis hole; Be provided with transmission shaft in described axis hole, transmission shaft is through middle part friction ring, little support ring and large support ring; The circular edge of described large support ring is provided with two groups of belt card sets, belt card sets comprises two opposed belt cards, and two groups of belt card sets are that cross is arranged; The joint of described little support ring and large support ring and middle part friction ring is respectively arranged with large belt buffer part and the belt lace buffer part of taper, and the tapering of large belt buffer part is less than the tapering of belt lace buffer part, and tapering difference is 0.5.The circular edge of described little support ring is provided with one group of belt card sets.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.Thrown away by little support ring and large support ring restriction belt, use safety, reliable transmission.Preventing belt from throwing away further by arranging belt card sets on little support ring and large support ring, improving Security.Little support ring and large support ring are hollow structure, and inside arranges support bar, improve its intensity, ensure that overall transmission intensity and working life, and reduce its weight, decrease energy loss.
Embodiment 2
The difference of the present embodiment and embodiment 1 is: the tapering of large belt buffer part is less than the tapering of belt lace buffer part, and tapering difference is 1.
Embodiment 3
The difference of the present embodiment and embodiment 1,2 is: the tapering of large belt buffer part is less than the tapering of belt lace buffer part, and tapering difference is 0.8.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in essential scope of the present utility model, the change made, remodeling, interpolation or replacement, all should belong to protection domain of the present utility model.
