The utility model discloses simple structure, the practicality is strong.
Description
Technical field
The utility model relates to sprocket arts field, is specially a kind of sprocket wheel.
Background technique
Traditional sprocket wheel is with the using process of chain interoperation, sprocket wheel easily and the phenomenon of chain generation slip teeth, meanwhile, the sprocket in traditional sprocket wheel, in long-term using process, is easily out of shape or bends, finally, the end face center of traditional sprocket wheel often sprocket body is provided with the center mounting hole socket-connected with hub spindle, and other parts on sprocket body end face between center mounting hole to sprocket are solid surfaces, such vibrational power flow, the sprocket weight not only made is heavier, and cost is higher.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model be to provide structural strength greatly, not easily slip teeth, fan thermal effect good and.
For achieving the above object, the utility model provides following technological scheme: a kind of sprocket wheel, comprise sprocket body, the circumferential surface of described sprocket body is evenly equipped with the sprocket that several are meshed with chain, the joint of described sprocket body and each sprocket is provided with First Transition ring cambered surface and the second transition ring cambered surface that shape is respectively ring-type, be provided with connecting plate between two sprockets of described arbitrary neighborhood, described sprocket body is provided with the erecting device for installing.
Further, described erecting device comprises annular array several curved support framves in sprocket body, and described curved support frame is provided with projection, and described projection comprises A line, some A line is positioned on same cylindrical side, and described curved support frame is also provided with positioning ring groove.
Further, the Extreme breadth of described sprocket and the width ratio of sprocket body are 4-5.
Further, the ventilation bend for dispelling the heat is formed between described curved support frame and sprocket body.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought: 1. erecting device of the present utility model comprises three the curved support framves of annular array in sprocket body, supporting frame is provided with projection, projection comprises A line, some A line is positioned on same cylindrical side, can sprocket wheel be positioned on hub spindle, and curved support frame is also provided with positioning ring groove, positioning ring groove is used for sprocket wheel and hub spindle are fixed, can not rotate, and the ventilation bend be formed between curved support frame and sprocket body for dispelling the heat, good heat dissipation effect, and alleviate the weight of sprocket body, reduce cost of production.2. the joint of sprocket body of the present utility model and each sprocket is provided with First Transition ring cambered surface and the second transition ring cambered surface that shape is respectively ring-type, and then add the surface stress of joint of sprocket body and sprocket, sprocket is not easily deformed or the bending imagination, and between two of arbitrary neighborhood sprockets, be provided with connecting plate, further enhance the structural strength between sprocket and sprocket.3. in the utility model, the Extreme breadth of sprocket and the width ratio of sprocket body are 4-5, and that is established by the Extreme breadth of sprocket is wider, and make sprocket wheel with the engagement process of chain, the phenomenon of slip teeth not easily occurs for sprocket wheel and chain.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is cross-sectional schematic of the present utility model.
Fig. 4 is rear view of the present utility model.
Embodiment
With reference to Fig. 1-Fig. 4, the utility model is described further.
A kind of sprocket wheel, comprise sprocket body 1, the circumferential surface of described sprocket body 1 is evenly equipped with the sprocket 11 that several are meshed with chain, described sprocket body 1 is provided with the joint of each sprocket 11 First Transition ring cambered surface 12 and the second transition ring cambered surface 13 that shape is respectively ring-type, be provided with connecting plate 14 between two sprockets 11 of described arbitrary neighborhood, described sprocket body 1 is provided with the erecting device for installing.
Sprocket body 1 is provided with the joint of each sprocket 11 First Transition ring cambered surface 12 and the second transition ring cambered surface 13 that shape is respectively ring-type, and then add the surface stress of sprocket body 1 and the joint of sprocket 11, sprocket 11 is not easily deformed or the bending imagination, and between two of arbitrary neighborhood sprockets 11, be provided with connecting plate 14, further enhance the structural strength between sprocket 11 and sprocket 11.
Further, described erecting device comprises annular array several curved support framves 2 in sprocket body 1, described curved support frame 2 is provided with protruding 21, described protruding 21 comprise A line 211, some A line 211 is positioned on same cylindrical side, and described curved support frame 2 is also provided with positioning ring groove 212.
Further, the Extreme breadth of described sprocket 11 and the width ratio of sprocket body 1 are 4-5.
The Extreme breadth of sprocket 11 and the width ratio of sprocket body 1 are 4-5, and that is established by the Extreme breadth of sprocket 11 is wider, and make sprocket wheel with the engagement process of chain, the phenomenon of slip teeth not easily occurs for sprocket wheel and chain.
Further, the ventilation bend 3 for dispelling the heat is formed between described curved support frame 2 and sprocket body 1.
Erecting device comprises three the curved support framves 2 of annular array in sprocket body 1, supporting frame is provided with protruding 21, protruding 21 comprise A line 211, some A line 211 is positioned on same cylindrical side, can sprocket wheel be positioned on hub spindle, and curved support frame 2 is also provided with positioning ring groove 212, positioning ring groove 212 is fixed for making sprocket wheel and hub spindle, can not rotate, and the ventilation bend 3 be formed between curved support frame 2 and sprocket body 1 for dispelling the heat, good heat dissipation effect and alleviate the weight of sprocket body 1, reduces cost of production.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
