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 sprockets, in particular to an integral flexible duplex sprocket, comprising a sprocket body, the front and rear parts of the sprocket body are fixedly connected with gear rings, and the inner side walls of the gear rings are fixedly connected There are several fixing mechanisms, the distance between two adjacent fixing mechanisms set on the same gear ring is the same, the middle part of the sprocket body is provided with a central hole, and a number of second meshing teeth are fixedly connected to the inner wall of the center hole , the distances between two adjacent second meshing teeth are the same, a hub is inserted inside the central hole, and a plurality of first meshing teeth are fixedly connected to the outer peripheral wall of the wheel hub. The wheel hub of the present invention is provided with a number of installation mechanisms, and the gear ring is provided with a number of corresponding fixing mechanisms, and connecting rods are provided between the corresponding installation mechanisms and the fixing mechanisms, which can facilitate the fixing of the wheel hub in the middle of the center hole during installation , so as to ensure that the rubber alloy can be evenly distributed between the outer wall of the hub and the inner 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...
