Seal assembly for rolling mill oil film bearing

A circular seal assembly in combination with for a roll in a rolling mill, the roll having a neck with a tapered section leading from a roll end face to a reduced diameter end section rotatably carried in a non-rotating chock on a film of bearing oil, with the chock being spaced axially from the roll end face to define a circular gap therebetween, said seal assembly spanning said gap and surrounding said tapered neck section, said seal assembly including a circular seal end plate secured to said chock and subdividing said gap into an inboard chamber adjacent said roll end face and an outboard chamber adjacent said chock, multiple seal components coacting with said seal end plate to prevent externally applied rolling solutions from penetrating into said outboard chamber and to prevent said bearing oil from escaping into said inboard chamber, and connecting means in an upper quadrant of said seal end plate for establishing a vent connection between said inboard and outboard chambers.

In an oil film bearing for a roll in a rolling mill, the roll having a neck with a tapered section leading from a roll end face to a reduced diameter section rotatably carried on a film of oil in a non-rotating chock, said bearing including a seal assembly adapted to encircle said tapered neck section between said roll end face and said chock, said circular seal end plate disposed in said seal assembly, said seal end plate being configured to subdivide said seal assembly into an inboard chamber adjacent said roll end face and an outboard chamber adjacent said chock, and connecting means in an upper quadrant of said seal end plate for providing a vent connection between said chambers.
