Abstract
In accordance with one aspect of the present disclosure, a wear ring assembly is provided for a railway roller bearing. The wear ring assembly includes a wear ring having a central opening for receiving a journal of a railway wheel assembly and an insert including a plurality of spacers configured to extend in the opening of the wear ring to separate the wear ring from the journal. The spacers are spaced apart from each other about the wear ring. The insert may include one or more flanges that separate the wear ring from a bearing cone.
Claims42
An insert for a wear ring of a railway roller bearing, the insert comprising:
- an annular body of a polymer material;
- and
- fingers of the annular body spaced apart from each other about the annular body, the annular body permitting at least one of the fingers to be deflected radially inward as the fingers are inserted into the wear ring.
A wear ring assembly for a railway roller bearing, the wear ring assembly comprising:
- a wear ring having a central opening for receiving a journal of a railway wheel assembly;
- and
- an insert including a plurality of spacers configured to extend in the opening of the wear ring to separate the wear ring from the journal, the spacers being separated from each other around the wear ring
- wherein the wear ring includes a pair of opposite sides and the central opening extends between the opposite sides;
- and
- the insert includes at least one flange extending along one of the sides of the wear ring to separate the wear ring from another component of the railway roller bearing.
A method of assembling a wear ring and an insert having a plurality of spacers, the method including:
- advancing at least one of the spacers of the insert into an opening of the wear ring;
- and
- advancing the remainder of the spacers of the insert into the opening of the wear ring to position the spacers around the opening of the wear ring.
A wear ring assembly for a railway roller bearing, the wear ring assembly comprising:
- a wear ring having an opening for receiving a journal of a railway wheel assembly;
- an insert including a plurality of fingers spaced apart from each other about the insert, the fingers configured to extend in the opening of the wear ring to separate wear ring from the journal;
- and
- the insert permitting at least one of the fingers to shift relative to the other fingers to facilitate assembly of the insert with the wear ring.
A wear ring assembly for a railway roller bearing, the wear ring assembly comprising:
- a wear ring having a central opening to receive a journal of a railway wheel assembly, the wear ring having a pair of opposite sides and the central opening extends between the opposite sides;
- and
- an annular insert to be received in the central opening of the wear ring and separate the wear ring from the journal;
- wherein the annular insert includes at least one flange to extend along one of the sides of the wear ring and separate the wear ring from another component of the railway roller bearing.
A wear ring assembly for a railway roller bearing, the wear ring assembly comprising:
- a wear ring having a central opening for receiving a journal of a railway wheel assembly;
- and
- an insert including a plurality of spacers configured to extend in the opening of the wear ring to separate the wear ring from the journal, the spacers being separated from each other around the wear ring;
- wherein the wear ring has a central axis and a predetermined length along the central axis;
- and
- the spacers of the insert extend along the wear ring for at least half of the length of the wear ring.
A wear ring assembly for a railway roller bearing, the wear ring assembly comprising:
- a wear ring having a central opening for receiving a journal of a railway wheel assembly;
- and
- an insert including a plurality of spacers configured to extend in the opening of the wear ring to separate the wear ring from the journal, the spacers being separated from each other around the wear ring;
- wherein the insert is annular and includes arcuate portions connecting the spacers;
- wherein the wear ring includes pairs of flexible arm portions, each pair of flexible arm portion connecting one of the spacers to two of the arcuate portions.
