[0052] In the prior art, the bearing is fixed on the connecting shaft by an interference fit. During the disassembly process of mechanical equipment or during the maintenance process of mechanical equipment, it is sometimes necessary to disassemble the bearing. Specifically, a hammer is used to hit a metal rod to slowly knock the bearing out of the connecting shaft. However, when the bearing is in a small space, the metal rod needs to be pressed against the side opposite to the disassembly direction of the bearing. When the bearing is disassembled by hitting the metal rod with a hammer, a large space is required. Due to space limitations, there is a problem of inconvenient disassembly. Moreover, when the bearing is disassembled by hitting the metal rod with a hammer, the metal rod will collide with the bearing, which is easy to damage the bearing and increase maintenance costs.

The two jacket bodies of the jacket are clamped on the bearing, the fixing sleeve is sleeved on the outside of the two jacket bodies, the locking sleeve is connected to the two jacket bodies, and the screw rod abuts against the axial direction of the connecting shaft, so that the bearing disassembly device can be moved along the axial direction of the connecting shaft. The bearing disassembly device requires less space when disassembling the bearing, and can be applied to bearings in narrow spaces. It is easy to disassemble and is not easy to cause damage to the bearing, thereby reducing maintenance costs.

[0069] The shape of the first baffle 112 is configured to correspond to the cross-sectional shape of the semi-cylindrical tube 111 .

[0070] The first baffle 112 can be fixed on the semi-cylindrical tube 111 by welding. In other embodiments, the first baffle 112 and the semi-cylindrical tube 111 are formed in one piece.

[0071] The radial width of the first baffle 112 in the semi-cylindrical tube 111 can be set according to the size of the space where the bearing 3 is located.

[0072] Furthermore, if Figure 4 As shown, the jacket body 11 further includes a second baffle 113, which is connected to one axial end of the semi-cylindrical tube 111 and is arranged radially outside the semi-cylindrical tube 111. The first baffle 112 and the second baffle 113 are located in the same plane.

[0073] The fixing sleeve 20 abuts between the locking sleeve 30 and the second baffle 40 in the axial direction of the semi-cylindrical tube 111 , so that the fixing sleeve 20 is fixed on the two jacket bodies 11 .

[0074] The fixing sleeve 20 may be a metal tube or a tube made of other materials.

[0075] The material of the second baffle 113 can be consistent with the material of the semi-cylindrical tube 111 .

[0076] The shape of the second baffle 113 may be the same as that of the first baffle 112 .

[0077] During the use of the bearing disassembly device, the two sleeve bodies 11 are first clamped on the bearing 3, and the first baffle 112 abuts against the end face of the bearing 3; then, the fixed sleeve 20 is sleeved on the outside of the two sleeve bodies 11, and the fixed sleeve 20 abuts against the second baffle 113, and the fixed sleeve 20 enables the two sleeve bodies 11 to clamp the bearing 3; then, the locking sleeve 30 is connected to the two sleeve bodies 11, the locking sleeve 30 abuts against the fixed sleeve 20, and the fixed sleeve 20 is fixed on the two sleeve bodies 11; then, the screw rod 40 is connected to the locking sleeve 30, and the screw rod 40 abuts on the axial direction of the connecting shaft 2; then, the screw rod 40 is rotated, and the screw rod 40 drives the locking sleeve 30 to move in the axial direction of the connecting shaft 2, and the locking sleeve 30 removes the bearing 3 from the connecting shaft 2 through the sleeve 10.

[0078] In some examples, such as Figure 4 As shown, the semi-cylindrical tube 111 includes a threaded section 1111 and a smooth tube section 1112, the threaded section 1111 and the smooth tube section 1112 are connected axially of the semi-cylindrical tube 111, the first baffle 112 and the second baffle 113 are located at one end of the smooth tube section 1112, the fixing sleeve 20 is sleeved on the smooth tube section 1112, and the locking sleeve 30 is threadedly connected to the threaded section 1111.

[0079] The threaded section 1111 is provided with threads, while the light pipe section 1112 is not provided with threads.

[0080] When the two sleeve bodies 11 are clamped on the bearing 3 and the first baffle 112 abuts against the end face of the bearing 3, the fixing sleeve 20 first passes through the threaded section 1111, and then the fixing sleeve 20 is sleeved on the light tube section 1112 and abuts against the second baffle 113, and then the locking sleeve 30 is threadedly connected to the threaded section 1111, and the locking sleeve 30 abuts against the fixing sleeve 20.
