Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of continuous casting roll bearing structure, specifically to a high-strength continuous casting roll bearing structure. 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] The bearing cage is a crucial component of a bearing, its primary function being to secure and guide the rolling elements, enabling them to rotate smoothly within the bearing. However, if the strength and lubrication of the bearing cage cannot meet the demands of high-load, high-speed operating conditions, it can easily lead to problems such as cage deformation and breakage, thereby affecting the bearing's performance and service life.

[0016] Beneficial effects:
[0017] This invention, through its fastening components, allows users to securely connect the roller shaft to the inner and outer rings. In use, the roller shaft is first brought into contact with the contact rings on both sides. Then, a threaded rod passes through the top collar-connecting ring and engages with the bottom threaded cylinder, securing the two sets of collars. Users can adjust the length of the threaded rod within the threaded cylinder to control the contact force between the contact rings and the roller shaft, improving the smoothness of the roller shaft's rotation. Simultaneously, the trumpet-shaped contact ring structure prevents the roller shaft from shifting or wobbling during rotation. Combined with the threaded rod's connection to the threaded cylinder, this enhances the roller shaft's strength. Attached Figure Description
