Abstract

A locking assembly for a bearing, such as a bearing for a rolling mill roll, the roll having a journal for the bearing, the bearing including a cylindrical sleeve member at its outermost end mounted on an axially outer portion of the journal, the end of the sleeve formed to have a radially inward shoulder, and a radially outwardly cylindrical projection, the shoulder having a wedge-shaped cam surface formed at its outer most axial surface, an axially movable outer nut constructed to pass over the journal and having a radially inwardly annular shoulder, the shoulder of the nut having a wedge-shaped cam surface arranged to cooperate with the cam surface of the sleeve shoulder to force the sleeve in an axially inward direction on its rotation when secured to the roll, the nut including several radially outward holes spaced angularly of the axis of the bearing for allowing the nut to be rotated, cooperative openings in the nut and the projection of the sleeve for receiving bolts for securing the nut to the sleeve once the two cam surfaces have been brought into a desired locking position, the nut having an axially outwardly annular shoulder, and the roll having a retainer member for engagement with the shoulder of the nut for securing the locking assembly in a fixed position relative to the roll and bearing.
