Problems solved by technology
[0003] In order to make the duplex sprocket jam when it works, parts such as the hub are inserted inside the sprocket, and rubber alloy is injected between the outer side of the hub and the inner side of the sprocket. During installation, the hub is prone to misalignment. The phenomenon makes the distribution of rubber alloy uneven and affects the normal operation of the sprocket. Most sprockets use parts such as cover plates to fix the hub inside the sprocket, but it is necessary to use processing equipment to punch holes on the sprocket. Then the cover plate can be fixed on the sprocket with bolts, the disassembly process is more inconvenient

The invention relates to the field of duplex sprocket wheels, in particular to an integral flexible duplex sprocket wheel. The integral flexible duplex sprocket wheel comprises a sprocket wheel body,wherein toothed rings are fixedly connected to the front part and the rear part of the sprocket wheel body, a plurality of fixing mechanisms are fixedly connected to the inner side walls of the toothed rings, the distance between every two adjacent fixing mechanisms arranged on the same toothed ring is the same, a central hole is formed in the middle of the sprocket wheel body, a plurality of second meshing teeth are fixedly connected to the inner side wall of the circumference of the central hole, the distance between every two adjacent second meshing teeth is the same, a hub is inserted inside the central hole, and a plurality of first meshing teeth are fixedly connected to the outer side wall of the circumference of the hub. According to the integral flexible duplex sprocket wheel, a plurality of mounting mechanisms are arranged on the hub, the plurality of corresponding fixing mechanisms are arranged on the toothed rings, and connecting rods are arranged between the corresponding mounting mechanisms and the corresponding fixing mechanisms so that the hub can be conveniently fixed in the middle of the central hole during mounting, and it is ensured that rubber alloy can be excessively uniformly distributed between the outer side wall of the hub and the inner side wall of the central hole.
Description
technical field [0001] The invention relates to the field of duplex sprockets, in particular to an integral flexible duplex sprocket. Background technique [0002] A sprocket is a wheel with sprockets, a sprocket is one of the components of a mechanical transmission structure, and a duplex sprocket is a type of sprocket. [0003] In order to make the duplex sprocket jam when it works, parts such as the hub are inserted inside the sprocket, and rubber alloy is injected between the outer side of the hub and the inner side of the sprocket. During installation, the hub is prone to misalignment. The phenomenon makes the distribution of rubber alloy uneven and affects the normal operation of the sprocket. Most sprockets use parts such as cover plates to fix the hub inside the sprocket, but it is necessary to use processing equipment to punch holes on the sprocket. Only then can the cover plate be fixed on the sprocket by bolts, and the dismounting process is relatively inconvenie...
