Claim 1
Independent Claim
201 words
In a rolling mill wherein the neck of a roll is rotatably supported in a lubricated bearing contained in a bearing chock, with a seal assembly located between the roll end face and the bearing chock for retaining lubricant in the bearing while excluding contaminants such as cooling water, dirt and mill scale therefrom, the said seal assembly including a stationary outer seal ring spaced from the roll end face with a drainage port therein, the improvement comprising: a flexible seal element having a circular body portion adapted to tightly surround the outer seal ring, a circular first lip integral with and extending outwardly away from said body portion at an angle relative to the axis thereof, said lip being arranged to sealing contact the roll end face, a drain opening in said body portion arranged for alignment with said drainage port, a second lip on said body portion surrounding said drain opening, and a baffle member attached to said body portion, said baffle member cooperating in radially spaced relationship with said second lip to provide a sealing labyrinth at said drain opening, said baffle member being sufficiently stiff to also reinforce said body portion against distortion at said drain opening.

In a rolling mill wherein the neck of a roll is rotatably supported in a lubricated bearing contained in a bearing chock, with a seal assembly located between the roll end face and the bearing chock for retaining lubricant in the bearing while excluding contaminants such as cooling water, dirt and mill scale therefrom, the said seal assembly including a stationary outer seal ring spaced from the roll end face with a drainage port therein, the improvement comprising: a flexible seal element having a circular body portion adapted to tightly surround the outer seal ring, a circular first lip integral with and extending outwardly away from said body portion at an angle relative to the axis thereof, said lip being arranged to sealing contact the roll end face, a drain opening in said body portion arranged for alignment with said drainage port, a second lip on said body portion surrounding said drain opening, and a baffle member attached to said body portion, said baffle member cooperating in radially spaced relationship with said second lip to provide a sealing labyrinth at said drain opening, said baffle member being sufficiently stiff to also reinforce said body portion against distortion at said drain opening.
Claim 3
Dependent Claim
39 words
The seal element as claimed in claim 1 wherein said second lip extends outwardly from said body portion in the opposite direction from said first mentioned lip and at an angle relative to the axis of said body portion.
Claim 4
Dependent Claim
47 words
The seal element as claimed in claim 2 wherein said body portion is provided with a cylindrical interior surface, and wherein said drain opening is defined in part by a sloping surface leading outwardly from said cylindrical inner surface to the outer edge of said second lip.
Claim 5
Dependent Claim
20 words
The seal element as claimed in claim 2 wherein said baffle member is spaced radially inwardly from said second lip.
Claim 6
Dependent Claim
