[0002] The sector section of a continuous casting machine is a critical part of the casting process. The sector section has a large number of equipment, including many free rolls, drive rolls, and other roll systems, and uses a large number of bearings. In the continuous casting machine, the rolls and bearings of the sector section are under high load, low speed, and sudden temperature rise. Moreover, many bearings must operate in an environment heavily contaminated by moisture, steam, and iron oxide chips. These harsh working conditions place high demands on the disassembly and assembly of bearings and bearing housings.

[0003] In the existing technology, traditional methods may be difficult to fix and operate stably during the disassembly of bearings. The fixed plate may be unstable due to the connection of the components when it is pulled upwards. Furthermore, the bearing may be fixed by only a single method, which may cause the bearing to slip off during disassembly, resulting in a low success rate of bearing disassembly.

[0004] Therefore, existing bearing housings have problems such as difficulty in disassembly, easy errors, and low success rate in disassembly during the assembly and disassembly process. Utility Model Content

A second connecting rod 11 is rotatably disposed on the upper end of the first connecting column 4. A first fixing ring 15 is disposed on the upper end of the second connecting rod 11, and a second fixing ring 17 is disposed on the lower end of the first fixing ring 15. A second stud 13 disposed on the second connecting rod 11 passes through the first fixing ring 15 and is threadedly installed with a first nut 14. Multiple connecting brackets 21 are fixedly connected to the upper end of the first fixing ring 15. A fixed plate 22 is fixedly connected to one end of the connecting frame 21 that is close to each other. The upper and lower ends of the fixed plate 22 are provided with second threaded grooves 23. A third stud 24 is installed in the inner thread of the second threaded groove 23. The first locking block 5 on the first connecting column 4 is first inserted into the ball gap in the first bearing 2 in an inclined manner. Then the first connecting column 4 is rotated so that the upper end of the first locking block 5 fits and limits the upper end of the inner wall concave ring of the first bearing 2. Then the second connecting rod 11 is threadedly installed on the first fixing ring 15 and the second fixing ring 17. When it is necessary to remove the bearing, the bearing mounting seat 1 is fixed. Then the third stud 24 is threadedly installed in the second threaded groove 23. By rotating the third stud 24, the second threaded groove 23 is displaced upward, thereby pulling the first bearing 2 out of the bearing mounting seat 1 by pulling force.

[0023] Please see Figures 1-3In this embodiment, a plurality of second connecting posts 16 are fixed to one end of the second fixing ring 17 and the first fixing ring 15 that are close to each other. A plurality of nut slots 19 are provided at the upper end of the first fixing ring 15. The inner wall of the nut slots 19 and the outer wall of the first nut 14 fit together. By the double-layer clamping of the second stud 13 and the second connecting rod 11 by the second fixing ring 17 and the first nut 14, the second connecting rod 11 can be prevented from tilting during the upward pulling of the fixing plate 22, thereby preventing the problem of disassembly and assembly errors.

In order to improve the efficiency of shaft removal, the first stud 7 can be threaded from the lower end of the first bearing 2 into the first threaded groove 6 on the first connecting post 4 to achieve a double-layer clamping effect and improve the success rate of shaft removal.

[0025] When removing the bearing from the bearing housing, firstly, the first locking block 5 on the first connecting post 4 is placed at an angle between the two balls on the first bearing 2. Then, the position of the first connecting post 4 is adjusted so that the upper end of the first locking block 5 is blocked by the inner wall of the concave ring of the first bearing 2 and cannot be removed. Alternatively, the lower end of the first bearing 2 can be further modified by threading the first stud 7 into the first threaded groove 6 on the first connecting post 4. Then, the lower end of the first bearing 2 is blocked and limited by the second locking block 8 on the first stud 7. After the first connecting post 4 is installed, the second fixing ring 17 and the first fixing ring 1 are then connected. 5 is inserted into the outer wall of the second connecting rod 11, so that the outer wall of the second connecting rod 11 and the inner wall of the second groove 18 fit together. The first nut 14 is placed in the nut slot 19. Then, the second connecting rod 11 is rotated to thread the second stud 13 onto the first nut 14. Next, the third stud 24 is threaded into the second threaded groove 23, so that the lower end of the third stud 24 and the upper end of the roller 3 fit together. Then, by rotating the device or manually turning the third stud 24, the fixing plate 22 drives the lower connecting parts to move upward as a whole, thereby pulling the first bearing 2 out of the bearing mounting seat 1, completing the disassembly of the bearing mounting seat 1.
