Description

Technical Field

[0001] The utility model relates to the technical field of bearing disassembly, in particular to a disassembly device for a rolling mill bearing. Background Art

[0002] Rolling mill bearings are used in the rolling industry, specifically for rolling nonferrous metals, ferrous metals, and non-metallic products. They are used on the rollers and drums of the rolling rolls. Disassembly of rolling mill bearings requires the use of specialized disassembly equipment.

[0003] When disassembling rolling mill bearings, existing disassembly devices usually use hydraulic pulling, and usually a pulling claw is installed at the front of the hydraulic puller to contact the rolling mill bearing. When the existing pulling claw applies external force to the rolling mill bearing, it is easy to cause local stress concentration, resulting in uneven force during the pulling process, which can easily cause damage to the bearing and the pulling claw itself. Therefore, it is necessary to provide a pulling claw that can apply external force evenly to reduce the risk of damage to the bearing and the pulling claw itself. Utility Model Content
