Seal assembly for rolling mill oil film bearing

摘要

An oil film bearing for a roll in a rolling mill is disclosed in which the roll has a neck with a tapered section (10) leading from a roll end face (12) to a reduced diameter section (14) rotatably supported in a non-rotating bearing chock (22). The chock is spaced axially from the roll end face to define a circular gap (23) therebetween and a circular seal assembly (24) spans the gap. The seal assembly comprises a rigid circular seal end plate (46) fixed to the chock at a location cooperating with associated resilient seal components to subdivide the gap into an inboard chamber (26) adjacent the roll end face and an outboard chamber (28) adjacent the chock. A vent connection (58) is provided in an upper quadrant of the seal end plate between the inboard and outboard chambers.
