[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a stable sprocket, which solves the problem that during the operation of the traditional sprocket, the inner wall of the chain hole is impacted and unevenly, which easily causes inconsistent wear and tear and affects the service life.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a stable sprocket, including a sprocket body, a plurality of energy absorption channels are opened inside the sprocket body, the plurality of energy absorption channels are distributed in an annular array, the plurality of energy absorption channels are connected to each other through connecting channels, a transmission piston plate is arranged inside the plurality of energy absorption channels, the side walls of the plurality of transmission piston plates close to the center position of the sprocket body are fixedly connected to a transmission shaft, one end of the transmission shaft away from the transmission piston plate extends to the sprocket hole position of the sprocket body and is fixedly connected to a negative pressure plate, a plurality of drive connecting channels are arranged inside the sprocket body, the plurality of drive connecting channels are distributed in an annular array, the plurality of drive connecting channels are distributed in an interval manner with the plurality of energy absorption channels, one end of the plurality of drive connecting channels are connected to the connecting channel, and the other end of the plurality of drive connecting channels is connected to the chain hole of the sprocket body through a plurality of small holes.

[0006] Preferably, a driving piston plate and two limit blocks are disposed inside each of the plurality of driving connection channels, and an oil storage material is filled between the driving piston plate and the limit blocks.

[0007] Preferably, a support restoration member is provided inside the oil storage material for supporting the oil storage material and ensuring the position restoration of the driving piston plate.

[0008] Working principle: When in use, when the local area of ​​the sprocket hole is subject to excessive pressure, the negative pressure plate will transfer the pressure to the hydraulic oil filled in the connecting channel and multiple performance channels through the transmission shaft, and the pressure in the local area will be dispersed by the hydraulic oil. At the same time, negative pressure will be applied to other transmission piston plates to hold the transmission parts in multiple directions, thereby improving the stability of the sprocket movement. When the inner side of the sprocket hole is subjected to greater pressure, the hydraulic oil will also squeeze the supporting restoration part through the driving piston plate, thereby applying negative pressure to the oil storage material, and the other end of the driving connecting channel is connected to the chain hole of the sprocket body through multiple small holes, thereby realizing the transfer of lubricating oil to the inside of the chain hole, which has a good focused lubrication effect when the inner wall of the chain hole is squeezed.

[0009] (III) Beneficial effects The present invention provides a stable sprocket, which has the following beneficial effects: 1. For this stable sprocket, when the local area of ​​the sprocket hole is subjected to excessive pressure, the negative pressure plate will transmit the pressure to the hydraulic oil filled in the connecting channel and multiple performance channels through the transmission shaft, disperse the pressure in the local area through the hydraulic oil, and at the same time, negative pressure is applied to other transmission piston plates, so that the transmission parts are clamped in multiple directions, thereby improving the stability of the sprocket movement.

[0010] 2. For this stable sprocket, when the inner side of the sprocket hole is subjected to greater pressure, the hydraulic oil will squeeze the supporting restoration part through the driving piston plate, thereby exerting negative pressure on the oil storage material. The other end of the driving connecting channel is connected to the chain hole of the sprocket body through multiple small holes, thereby realizing the transfer of lubricating oil to the inside of the chain hole, which has a good focused lubrication effect when the inner wall of the chain hole is squeezed.
