Abstract
Abstract A multiple element bearing seal in which a first annular ring of resilient nonmetallic material is positioned in oppositely disposed grooves in the inner and outer racerings of the bearing assembly. The first annular ring has a radial face defined by an outer peripheral edge and an inner annular edge and an integral extension extending outwardly divergent to the radial face. The integral extension is in a running contact fit with one of the inner and outer racerings and applies pressure to the first annular ring to maintain it in a running contact fit with the racering grooves. A second annular sealing ring of resilient nonmetallic material has an edge positioned in one of the grooves. The outer edge extends axially outwardly of the bearing assembly and rests on the corner face of the other racering in a contact seal.

Claim 1
Independent Claim
312 words
A bearing seal for sealing a bearing assembly including outer and inner annular members which are rotatable relative to one another and which are spaced apart for receiving anti-friction elements and lubricant therebetween, said annular members having oppositely disposed grooves in each axial end thereof and at least one of said annular members having corner portions axially outwardly of the grooves, and a pair of annular sealing structures, one for each axial end of said members, each of said sealing structures including in combination, a first annular sealing ring comprising a radial body portion with an outer peripheral sealing portion extending radially outwardly therefrom and being positioned in the assembly to fit into a groove in said outer member and with an inner annular sealing portion extending radially inwardly therefrom and being positioned in the assembly to fit into a groove in said inner member, said first annular sealing ring further including a portion molded integral to said body portion and extending axially outwardly in an interference fit to provide a reservoir therebetween with the specified one annular member, and a second annular sealing ring comprising a radial body portion with an outer peripheral sealing portion extending radially outwardly therefrom and with an inner annular sealing portion extending radially inwardly therefrom, said second annular sealing ring being positioned in the assembly with one of said outer peripheral or inner annular sealing portions being positioned adjacent one of said outer peripheral and inner annular sealing portions of said first annular sealing ring positioned in the groove in the annular member opposite the specified one annular member, and the other of said outer peripheral and inner annular sealing portions extending axially outwardly from the assembly with said radial body portion extending across the space between the annular members to engage the corner portion of the specified one annular member in a running contact seal.
Claim 2
Dependent Claim
312 words
A bearing seal for sealing a bearing assembly including outer and inner annular members which are rotatable relative to one another and which are spaced apart for receiving anti-friction elements and lubricant therebetween, said annular members having oppositely disposed grooves in each axial end thereof and at least one of said annular members having corner portions axially outwardly of the grooves, and a pair of annular sealing structures, one for each axial end of said members, each of said sealing structures including in combination, a first annular sealing ring comprising a radial body portion with an outer peripheral sealing portion extending radially outwardly therefrom and being positioned in the assembly to fit into a groove in said outer member and with an inner annular sealing portion extending radially inwardly therefrom and being positioned in the assembly to fit into a groove in said inner member, said first annular sealing ring further including a portion molded integral to said body portion and extending axially outwardly in an interference fit to provide a reservoir therebetween with the specified one annular member, and a second annular sealing ring comprising a radial body portion with an outer peripheral sealing portion extending radially outwardly therefrom and with an inner annular sealing portion extending radially inwardly therefrom, said second annular sealing ring being positioned in the assembly with one of said outer peripheral or inner annular sealing portions being positioned adjacent one of said outer peripheral and inner annular sealing portions of said first annular sealing ring positioned in the groove in the annular member opposite the specified one annular member, and the other of said outer peripheral and inner annular sealing portions extending axially outwardly from the assembly with said radial body portion extending across the space between the annular members to engage the corner portion of the specified one annular member in a running contact seal.
Claim 3
Dependent Claim
74 words
The bearing seal of claim 1 wherein said first annular sealing ring is positioned in the bearing assembly with said outer peripheral edge portion fitted into the annular groove in said outer member and said inner annular edge portion fitted into the annular groove in said inner member, and said integrally molded portion is an extension lip extending divergently axially outwardly from said radial body portion in an interference fit with the inner member.
Claim 4
Dependent Claim
74 words
The bearing seal of claim 1 wherein said first annular sealing ring is positioned in the bearing assembly with said outer peripheral edge portion fitted into the annular groove in said outer member and said inner annular edge portion fitted into the annular groove in said inner member, and said integrally molded portion is an extension lip extending divergently axially outwardly from said radial body portion in an interference fIt with the outer member.
