Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of continuous casting roll bearing structure, specifically to a continuous casting roll bearing structure that effectively reduces wear. Background Technology
[0002] In steel mills, equipment frequently experiences issues such as roller failure and shaft breakage. Tracking these incidents revealed that both types of rollers suffered damage to their intermediate bearings, with a failure rate reaching 90%. Under normal circumstances, these rollers can be used online for 10-12 months or longer. Even after improvements were implemented, bearing damage persists at a remarkably high rate.
[0003] Recent inspections of bearings in sections that have been online for 6.5 months revealed significant damage, with over 30% of the bearings being taken offline showing signs of wear. This wear was evident in almost every bearing. Given the current online cycle, this is impacting production schedules and severely hindering section preparation and roller repair. Utility Model Content
[0004] Technical problems to be solved
[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a continuous casting roll bearing structure that effectively reduces wear. It can effectively solve the problem that bearing wear has a significant impact on the service life of the bearing after it leaves the production line, affects the production rhythm, and seriously restricts the section preparation and roll repair processes.
[0006] Technical solution
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] This utility model provides a continuous casting roll bearing structure that effectively reduces wear, including an outer ring and an inner ring. The inner sides of the upper and lower ends of the outer ring and the outer sides of the upper and lower ends of the inner ring are provided with locking rings. The outer ring and the inner ring are concentrically arranged. Two sets of positioning frames are provided in the middle of the two rings. The two sets of positioning frames are fixedly connected by positioning plates. A continuous casting roll rod is provided between the positioning plates.
[0009] Furthermore, a circular hole is provided through the middle of the continuous casting roller, a circular rod is fixed between the two sets of positioning frames, and the continuous casting roller is sleeved on the circular rod.
[0010] Furthermore, the inner wall of the outer ring has an arc-shaped structure, and the inner wall of the inner ring maintains line contact with the continuous casting roller.
[0011] Furthermore, the locking ring is fixed to the outside of the positioning frame.
[0012] Furthermore, the continuous casting roller is spindle-shaped.
[0013] Beneficial effects
[0014] The technical solution provided by this utility model, compared with the known public technology, has the following advantages:
[0015] Beneficial effects:
[0016] This invention utilizes a spindle-shaped continuous casting roller structure. A round rod passes through the roller structure to achieve a fixed connection with the positioning frame structures on both sides. Locking ring structures are provided on the outer and inner rings to first achieve a fixed connection with the positioning frame, limiting the shaking of the inner positioning frame. The inner wall of the outer ring has an arc-shaped structure, which is fixed to the outer ring through the positioning frame. The inner wall has line contact with the side wall of the continuous casting roller, so when the force direction on the inner ring is different, the inner ring can tilt to one side. One side of the continuous casting roller can always maintain contact with the inner ring, reducing the possibility of inner ring breakage and extending service life. Attached Figure Description

[0025] Example: A continuous casting roll bearing structure that effectively reduces wear, as shown in the attached figure. Figure 1 -Appendix Figure 4 It includes an outer ring 1 and an inner ring 2. The inner sides of the upper and lower ends of the outer ring 1 and the outer sides of the upper and lower ends of the inner ring 2 are provided with locking rings 6. The outer ring 1 and the inner ring 2 are concentrically arranged. Two sets of positioning frames 3 are provided in the middle of the two. The two sets of positioning frames 3 are fixedly connected by positioning plates 4. A continuous casting roller 5 is provided between the positioning plates 4.
[0026] A circular hole is provided through the middle of the continuous casting roller 5. A circular rod is fixed between the two sets of positioning frames 3, and the continuous casting roller 5 is sleeved on the outside of the circular rod. The inner wall of the outer ring 1 has an arc-shaped structure, and the inner wall of the inner ring 2 maintains line contact with the continuous casting roller 5. Through the spindle-shaped continuous casting roller 5 structure, the circular rod passes through the continuous casting roller 5 structure to achieve a fixed connection with the positioning frames 3 on both sides. The outer ring 1 and the inner ring 2 are both provided with locking rings 6, which first achieve a fixed connection with the positioning frames 3 and limit the shaking of the inner positioning frames 3. The inner wall of the outer ring 1 has an arc-shaped structure, which is fixed to the outer ring 1 through the positioning frames 3. The inner wall of the inner ring 2 is in line contact with the side wall of the continuous casting roller 5. Therefore, when the force direction of the inner ring 2 is different, the inner ring 2 can tilt to one side, and one side of the continuous casting roller 5 can always maintain contact with the inner ring 2, reducing the possibility of the inner ring 2 breaking and extending the service life.
[0027] The locking ring 6 is fixed on the outside of the positioning frame 3; the continuous casting roller 5 is spindle-shaped, and the spindle-shaped continuous casting roller 5 structure can be fixed with the arc-shaped outer ring 1 and contact the inner ring 2 on the inner side, so that the inner ring 2 can be offset, while the locking ring 6 on the inner ring 2 can avoid the problem of excessive lateral displacement.
