[0007] Preferably, a plurality of annularly distributed and axially arranged T-shaped sliding grooves are formed in the roller body.

[0008] Preferably, a plurality of annularly distributed and axially arranged T-shaped feet are fixedly embedded in the inner sleeve wall of the rubber sleeve; and the T-shaped feet are respectively inserted into the T-shaped sliding grooves formed in the roller body and are in sliding connection with the T-shaped sliding grooves.

[0009] Preferably, a plurality of annularly distributed and radially arranged threaded holes are formed in the end of the roller body provided with the annular groove.

[0010] Preferably, a plurality of annularly distributed and radially arranged mounting holes are formed in the clamping end cover; and bolts for connecting the threaded holes are inserted into the mounting holes.

[0011] Preferably, an abutting A ring is fixedly mounted at the end of the roller body away from the annular groove.

[0012] Preferably, an abutting B ring is fixedly mounted on the end face of the clamping end cover.

[0013] Preferably, the roller body is fixedly installed with a roller shaft at both ends.

[0014] Compared with the related art, the shaft roller structure with replaceable roller sleeve has the following beneficial effects:

[0015] The T-shaped sliding groove on the roller body and the T-shaped foot on the rubber sleeve are in sliding connection, the gear and the sawtooth part of the clamping end cover are in engagement, the rubber sleeve is quickly disassembled, the maintenance time is significantly reduced, the axial fitting design of the T-shaped sliding groove and the T-shaped foot effectively prevents the rubber sleeve from rotating around the roller body, improves the operation stability, and the gear engagement and the screw bolt cooperate to ensure the firm fixation of the clamping end cover and avoid loosening.
