Adjusting device for assembling roll and bearing and assembling method for roll and bearing

Abstract

The invention discloses a regulation device for assembly of a roller and a bearing. The regulation device comprises a fixing part (6), a fixing bolt (8), a regulation part (7) and a regulation bolt (9), wherein a connecting hole (61) which communicates with first threaded holes (31, 32) is formed in the fixing part (6); the fixing bolt (8) penetrates through the connecting hole (61) and is matched with the first threaded holes (31, 32) so as to fixedly connect the fixing part (6) and an eccentric sleeve (3); a second threaded hole (71) is formed in the regulation part (7) and is also used for being arranged opposite to an inner ring (5); the regulation bolt (9) is in threaded matching with the second threaded hole (71) so as to apply pressing force to the inner ring (5); and the direction of the pressing force is parallel to the axial line of the inner ring (5). According to the technical scheme, the problems that the labor intensity is larger, and the inner ring of the bearing is liable to damage caused by adopting a hammer knocking manner to ensure return of the inner ring of the bearing in the mounting process of the roller are solved. The invention also discloses an assembling method for the roller and the bearing.

Description

technical field [0001] The invention relates to the technical field of roll assembly, in particular to an adjusting device for assembling a roll and a bearing and a method for assembling a roll and a bearing. Background technique [0002] Rolling mills are more commonly used mechanical processing equipment, and there are many types, and universal rolling mills are the most common one. During the assembly process of the universal rolling mill, the assembly of the bearing seat and the roll on the rolling mill frame needs to be completed by the roll assembly trolley. Therefore, the hydraulic system of the roll assembly trolley, when pushing the end of the roll into the inner ring of the bearing, will push the inner ring towards the outside of the chock, which will eventually cause a large axial force of the inner ring relative to the outer ring of the bearing. Deviation affects the installation quality of the bearing. [0003] In order to ensure the return of the inner ring o...
