[0011] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0012] like Figure 1-Figure 2 As shown, a cylindrical roller bearing disassembly cylinder comprises a connecting piece 1, a supporting piece 2, a bearing inner ring fixing tooth 3, a hollow sliding rod 4, a connecting rod 5, a rotating wheel 6, an arc-shaped clamping block 7, a bearing 8, and a rotating handle 9. The connecting piece 1 is installed with supporting pieces 2 on all sides of the bottom, and the outer side of the bottom of the supporting piece 2 is installed with bearing inner ring fixing teeth 3. The connecting piece 1 is installed with a hollow sliding rod 4 on the top, and a connecting rod 5 is installed inside the hollow sliding rod 4. The bottom of the connecting rod 5 is located in the supporting piece 2 and a rotating wheel 6 is installed. Arc-shaped clamping blocks 7 are installed around the rotating wheel 6. Each arc-shaped clamping block 7 is located between adjacent supporting pieces 2, and the arc-shaped clamping block 7 can be driven by the rotating wheel 6 to lift the adjacent supporting pieces 2 outward, so that the bearing inner ring fixing teeth 3 on the supporting piece 2 fix the inner ring of the bearing to be disassembled, the top of the hollow sliding rod 4 is installed with a bearing 8, and the top of the connecting rod 5 is connected by the bearing 8, and the top of the connecting rod 5 is installed with a rotating handle 9.
