Abstract
The utility model discloses a combined chain wheel convenient to rapidly disassemble and assemble. The combined chain wheel comprises a wheel hub, wherein a key groove is formed in the inner circumferential side of the wheel hub, a ring of flange is arranged at the position, facing the outer circumferential side of the wheel hub, of the outer ring of the wheel hub in a protrusion mode, one side end face of the flange is fixed with a chain wheel body through bolts, the chain wheel body is provided with chain wheel teeth, and the chain wheel body is formed by two semi-circular-ring-shaped semi chain wheel bodies in a splicing mode. A general chain wheel of a traditional structure is designed to be a combined type, the problem that disassembly and assembly are difficult is well solved, disassembly efficiency and assembly efficiency are improved, and the production efficiency is prevented from being affected.
Description
Technical field
The utility model relates to sprocket wheel.
Background technique
The chain transmission is widely used in mechanical transmission, the mass transport occasion of industry-by-industry; need to change for the sprocket wheel that reaches working life or accidental damage; but many time; in order to guarantee the continuous high-efficient operation of production line; the length of shutting down the repair and replacement time directly influences production line efficiency, therefore gives the dismounting time of repair and replacement seldom.Yet, most of mechanical transmission and conveying occasion, the sprocket wheel dismounting is very difficult, waste time and energy, the transmission device that has even a plurality of sprocket wheels are housed at a transmission shaft, the sprocket wheel that is positioned at intermediate portion needs to remove behind many miscellaneous parts especially could dismounting, directly influences the working time of production line, influences manufacturing efficiency then.
The model utility content
Technical problem to be solved in the utility model just provides a kind of composite sprocket of being convenient to fast assembling-disassembling, improves dismounting efficient, avoids influencing manufacturing efficiency.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of composite sprocket of being convenient to fast assembling-disassembling, it is characterized in that: comprise wheel hub, the wheel hub inner circumferential side is provided with keyway, described wheel hub outer ring surface is to the outstanding circle flange that is provided with of wheel hub outer circumferential sides, a described flange wherein side end face is fixed by bolt and the sprocket body that is provided with sprocket tooth, and described sprocket body is put together by half sprocket body of two semi-round ring shapes.
Preferably, described two and half sprocket body are located finger setting on the hub flange end face by one respectively.
Preferably, the line of described two locating studs is by the keyway of wheel hub center and wheel hub inner circumferential side.
Preferably, described half sprocket body is fastening by four bolts and hub flange.
Preferably, be provided with pad between the nut of bolt and half sprocket body.
The utility model becomes combination form with the sprocket design of common conventional construction, has well solved the problem of dismounting difficulty, has improved dismounting efficient, avoids influencing manufacturing efficiency.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is the composite sprocket plan view;
Fig. 2 is the composite sprocket sectional view.
Embodiment
Specify the concrete structure of composite sprocket below in conjunction with Fig. 1 and Fig. 2, it comprises wheel hub 1, the wheel hub inner circumferential side is provided with keyway, described wheel hub outer ring surface is to the outstanding circle flange 10 that is provided with of wheel hub outer circumferential sides, a described flange wherein side end face is fixing with the sprocket body 2 that is provided with sprocket tooth by bolt 3, and described sprocket body 2 is put together by half sprocket body of two semi-round ring shapes.Described two and half sprocket body are positioned on the hub flange end face by a locating stud 4 respectively.The line of described two locating studs 4 is by the keyway of wheel hub center and wheel hub inner circumferential side.Described half sprocket body is fastening by four bolts and hub flange.Be provided with pad between the nut of bolt and half sprocket body.Be provided with pad between the junction plane 5 of described two and half sprocket body.
Composite sprocket of the present utility model separates sprocket wheel and chain engagement the body position of damaging easily and the wheel hub position that sprocket wheel and transmission shaft assemble, and becomes whole by bolts assemblies, simultaneously, sprocket body is made symmetrical halves.By this design, no matter sprocket wheel is contained in any position of transmission shaft, only need bolt is unclamped, unload the sprocket body of two halves, just can replace with new satisfactory sprocket wheel, and the wheel hub position does not need to pull down, greatly saved the dismounting time, simultaneously, the repair and replacement cost of sprocket wheel also greatly reduces, because the wheel hub position that sprocket wheel matches with transmission shaft scarcely need change, and the sprocket wheel of conventional construction is in case replacing, just must wholely pull down replacing, and in fact the wheel hub position is not easy generally to damage.
In addition, be the sprocket body position consistency when changing and assemble again that makes two halves, design has locating stud to guarantee relative position.
