Abstract
Abstract An antifriction bearing with an outer ring, inner ring, a row of balls between the rings and an open radial space between the rings. A sealing disc at one axial side of the rings seals the open space between the outer and inner rings. The sealing disc also serves as a pulse ring. It comprises a metal part having a plurality of openings of preferably rectangular cross-section through it. The metal part is at least partially surrounded by a covering nonmetallic layer of plastic or rubber which also fills the openings. The sealing disc is attached to one of the rings, and preferably to the outer ring to rotate with the outer ring with respect to the other, inner ring and the sealing disc is sealed to the inner ring.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
167 words
An antifriction bearing with a pulse ring for measuring the speed of rotation of the bearing, the bearing comprising: an outer ring of the bearing, an inner ring of the bearing spaced radially inward from the outer ring of the bearing and a row of bearing rolling elements guided between the outer and inner rings and rolling therebetween; the bearing having a radial space defined between the inner and outer rings; the bearing having an axial side; generally toward the axial side of the bearing, an annular sealing disc is disposed in the radial space between the inner ring and the outer ring and seals that radial space; the sealing disc being comprised of an annular metal part held to one of the rings and moving with the one ring and moving with respect to the other ring as the rings rotate relative to one another; a plurality of openings defined in the metal part for being sensed as the pulse ring rotates with the one ring.
Claim 2
Dependent Claim
167 words
An antifriction bearing with a pulse ring for measuring the speed of rotation of the bearing, the bearing comprising: an outer ring of the bearing, an inner ring of the bearing spaced radially inward from the outer ring of the bearing and a row of bearing rolling elements guided between the outer and inner rings and rolling therebetween; the bearing having a radial space defined between the inner and outer rings; the bearing having an axial side; generally toward the axial side of the bearing, an annular sealing disc is disposed in the radial space between the inner ring and the outer ring and seals that radial space; the sealing disc being comprised of an annular metal part held to one of the rings and moving with the one ring and moving with respect to the other ring as the rings rotate relative to one another; a plurality of openings defined in the metal part for being sensed as the pulse ring rotates with the one ring.
Claim 3
Dependent Claim
17 words
The antifriction bearing of claim 1, wherein the openings in the metal part are of rectangular cross-section.
Claim 4
Dependent Claim
34 words
The antifriction bearing of claim 2, wherein measured around the sealing disc, each rectangular opening has a center line, and each center line of a rectangular opening is along a radius of the bearing.
Claim 5
Dependent Claim
15 words
The antifriction bearing of claim 3, wherein all the rectangular openings have the same shape.
Claim 6
Dependent Claim
19 words
The antifriction bearing of claim 2, wherein the metal part is at least in part surrounded by nonmetallic material.
Claim 7
Dependent Claim
13 words
The antifriction bearing of claim 5, wherein the nonmetallic material is a plastic.
Claim 8
Dependent Claim
13 words
The antifriction bearing of claim 5, wherein the nonmetallic material is a rubber.
Claim 9
Dependent Claim
24 words
The antifriction bearing of claim 5, wherein the nonmetallic material so surrounds the metal part as to fill the openings through the metal part.
Claim 10
Dependent Claim
55 words
The antifriction bearing of claim 5, wherein the metal part is of a radial height that it does not extend into contact with either of the inner and outer rings of the bearing and the nonmetallic part extends radially beyond the metal part to engage the one ring and to seal against the other ring.
Claim 11
Dependent Claim
15 words
The antifriction bearing of claim 9, wherein the nonmetallic material completely surrounds the metal part.
Claim 12
Dependent Claim
43 words
The antifriction bearing of claim 9, wherein the sealing disc is secured to the outer ring to rotate along with the outer ring and the sealing disc ride over the inner ring as the outer ring rotates with respect to the inner ring.
Claim 13
Dependent Claim
43 words
The antifriction bearing of claim 1, wherein the sealing disc is secured to the outer ring to rotate along with the outer ring and the sealing disc ride over the inner ring as the outer ring rotates with respect to the inner ring.
Claim 14
Dependent Claim
34 words
The antifriction bearing of claim 1, wherein the antifriction bearing is a ball bearing and the rolling elements are bearing balls and the outer and inner rings of the bearing support the bearing walls.
