Abstract
Abstract A sealing ring and mounting thereof for an antifriction bearing, which has a sealing edge for resiliently engaging one end face of one race ring of an antifriction bearing and also has a conically shaped arm for engagement with a conical surface on either the other race ring of the antifriction bearing or a conical surface of a housing or a shaft.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
In combination with first means comprising supporting means and with second means comprising an antifriction bearing supported by said supporting means and having an outer race ring and an inner race ring: a sealing ring having a radially extending annular portion provided at its outer end with a first annular bentoff portion and at its inner end with a second annular bentoff portion, one of said annular bentoff portions having its free end forming a sealing edge in resilient sealing engagement with an end face of one of said race rings, and the other annular bentoff portion of said sealing ring forming an annular conically shaped clamping and centering surface for substantially doubly enhanced clamping engagement with one of said first and second means and for clamping and centering said sealing ring positively thereon.
Claim 2
Dependent Claim
134 words
In combination with first means comprising supporting means and with second means comprising an antifriction bearing supported by said supporting means and having an outer race ring and an inner race ring: a sealing ring having a radially extending annular portion provided at its outer end with a first annular bentoff portion and at its inner end with a second annular bentoff portion, one of said annular bentoff portions having its free end forming a sealing edge in resilient sealing engagement with an end face of one of said race rings, and the other annular bentoff portion of said sealing ring forming an annular conically shaped clamping and centering surface for substantially doubly enhanced clamping engagement with one of said first and second means and for clamping and centering said sealing ring positively thereon.
Claim 3
Dependent Claim
179 words
In combination with first means comprising supporting means and with second means comprising an antifriction bearing supported by said supporting means and having an outer race ring and an inner race ring: a sealing ring having a radially extending annular portion provided at its outer end with a first annular bentoff portion and at its inner end with a second annular bentoff portion, one of said annular bentoff portions having its free end forming a sealing edge in resilient sealing engagement with an end face of one of said race rings, and the other annular bentoff portion of said sealing ring forming an annular conically shaped clamping and centering surface for substantially doubly enhanced clamping engagement with one of said first and second means and for clamping and centering said sealing ring positively thereon, one of said first and second means having a tapering surface tapering in conformity with and engaged by said conically shaped clamping and centering surface, and the otheR one of said first and second means having a shoulder at one end of said tapering surface.
Claim 4
Dependent Claim
179 words
In combination with first means comprising supporting means and with second means comprising an antifriction bearing supported by said supporting means and having an outer race ring and an inner race ring: a sealing ring having a radially extending annular portion provided at its outer end with a first annular bentoff portion and at its inner end with a second annular bentoff portion, one of said annular bentoff portions having its free end forming a sealing edge in resilient sealing engagement with an end face of one of said race rings, and the other annular bentoff portion of said sealing ring forming an annular conically shaped clamping and centering surface for substantially doubly enhanced clamping engagement with one of said first and second means and for clamping and centering said sealing ring positively thereon, one of said first and second means having a tapering surface tapering in conformity with and engaged by said conically shaped clamping and centering surface, and the otheR one of said first and second means having a shoulder at one end of said tapering surface.
Claim 5
Dependent Claim
36 words
An arrangement in combination according to claim 2, in which that annular bentoff portion the free end of which forms a sealing edge extends at least approximately perpendicularly to the race ring end face engaged thereby.
Claim 6
Dependent Claim
54 words
An arrangement in combination according to claim 2, in which said conically shaped clamping and centering surface of said sealing ring has a tapering angle which is less than the angle of friction between said clamping and centering surface and the surface engaged thereby and pertaining to one of said first and second means.
Claim 7
Dependent Claim
56 words
An arrangement in combination according to claim 2, in which one of said first and second means has an annular step partially formed by a tapering surface for engagement by said conically shaped clamping and centering surface of said sealing ring, said tapering surface tapering in the direction of action of said clamping and centering surface.
Claim 8
Dependent Claim
39 words
An arrangement in combination according to claim 2, in which the sealing edge of said sealing ring engages the outer race ring, and in which the outer diameter of said shoulder exceeds the maximum diameter of said tapering surface.
Claim 9
Dependent Claim
41 words
An arrangement in combination according to claim 2, in which the sealing edge of said sealing ring engages the inner race ring and in which the inner diameter of said shoulder is less than the shortest diameter of said tapering surface.
