[0006] Preferably, the interior of the liquid storage cavity is filled with hydraulic oil.

[0007] Preferably, the pressure transmission channel and the negative pressure channel are distributed at intervals.

[0008] Working principle: When in use, when the sprocket is in working condition, especially under heavy load, when the sprocket applies pressure to the local movable teeth and pressure blocks, the pressure will be transferred to the movable teeth and pressure blocks in other positions through the negative pressure rod and the pressure transmission rod, thereby improving the degree of fit between the chain and the sprocket, thereby improving safety, and can improve the operating safety of the equipment while sharing the pressure.

[0009] (3) Beneficial effects The present invention provides a block-type movable tooth sprocket assembly. It has the following beneficial effects: This pressure block type movable tooth sprocket assembly, when the sprocket is in working condition, especially under heavy load, when the sprocket applies pressure to local movable teeth and pressure blocks, the pressure will be transferred to movable teeth and pressure blocks in other positions through the negative pressure rod and the pressure transmission rod, thereby improving the degree of fit between the chain and the sprocket, thereby improving safety, and can improve the operating safety of the equipment while sharing the pressure.
