Side supporting bearing and rolling mill side supporting mechanism

Abstract

The invention relates to a side supporting bearing which comprises an inner ring, an outer ring, two check rings on the left and right sides and a plurality of cylindrical rollers. The surface of the outer ring forms a middle arc face, an upper arc face and a lower arc face. The upper arc face and the lower arc face of the side supporting bearing are matched with the end faces of upper and lower working rollers of a rolling mill, and the phenomenon of stress concentration of the outer ring of the bearing can be reduced. A rolling mill side supporting mechanism comprises a rack provided with the upper working roller and the lower working roller, and side supporting devices are arranged at the positions, on the two sides of the two working rollers, of the rack; and each side supporting device comprises a vertically and fixedly arranged supporting shaft, the upper arc face of the side supporting bearing is located on one side of the end face of the upper working roller, and the lower arc face of the side supporting bearing is located on one side of the end face of the lower working roller. Axial component force generated to the outer ring of the bearing when the upper and lower working rollers move vertically can be avoided, and the problem about cracking of a stopping edge of the outer ring of the bearing is solved.

Description

technical field [0001] The invention relates to a side support bearing and a side support mechanism of a rolling mill. Background technique [0002] When the rolling mill is working, the upper and lower work rolls are used to roll the steel bars and steel plates between the roller tables. Since the steel plates to be rolled are not flat steel plates, the upper and lower work rolls are working on the steel plates in the roller tables. When rolling, there will be an axial component force on the work rolls. In the past rolling mills, the method adopted to overcome this axial force of the work rolls is to set side support bearings on both sides of the two work rolls. ,Such as figure 1 As mentioned above, the upper side support bearing 30 cooperates with the end surface of the upper work roll 10 to limit the axial movement of the upper work roll 10, and the lower side support bearing 40 cooperates with the end surface of the lower work roll 20 to limit the axial movement of the ...
