Description

Technical Field

[0001] The utility model belongs to the technical field of continuous casting roller bearing disassembly, and in particular relates to a continuous casting roller bearing disassembly device. Background Art

[0002] In the repair process of continuous casting rollers, the bearing seat is one of the key equipment, and its performance and service life directly affect the service life of the continuous casting machine and product quality. It is necessary to replace the inner hole bearing of the bearing seat. However, the traditional bearing removal is to directly hammer the bearing surface with a sledgehammer, which is easy to damage the inner hole of the bearing seat, and has problems such as low work efficiency and heavy physical work, which to a certain extent affects the progress of continuous casting repair. Therefore, an efficient and convenient continuous casting roller bearing removal device is developed to improve the maintenance and replacement efficiency of continuous casting rollers, reduce production costs, and ensure the continuity and stability of continuous casting production.
