Apparatus for rotatably supporting the neck of a roll in a rolling mill

摘要

Apparatus for rotatably supporting the neck of a roll in a rolling mill, including a bearing assembly configured and dimensioned to surround the roll neck, a chock containing the bearing assembly, and a support for the chock, with the chock and the support being in contact with each other at an interface having a radius of curvature arranged to accommodate relative movement between the chock and the support in response to bending loads applied to the roll. A lubricant is introduced under pressure at the interface between the chock and the support to thereby reduce frictional resistance to relative movement therebetween.
