Abstract
A ring for use in a roller bearing includes an outer wall. The ring further includes two side walls extending away from the outer wall, defining a cavity therebetween for receiving at least one roller, and each of the two side walls having an outer edge at a location facing the cavity and farthest from the outer wall. The ring further includes a curved crown extending inward from at least one of the two side walls and configured to contact the at least one roller to reduce wear of the outer edge.

A ring for use in a roller bearing having an axis, the ring comprising:
- an outer wall;
- two side walls extending away from the outer wall, defining a cavity therebetween for receiving at least one roller, and each of the two side walls having an outer edge at a location facing the cavity and farthest from the outer wall and an inner edge at a location facing the cavity and closest to the outer wall, the outer edge being radially aligned with the inner edge such that the two side walls extend in a direction perpendicular to the outer wall;
- and
- a curved crown extending inward from at least one of the two side walls and configured to contact the at least one roller to reduce wear of the outer edge,
- wherein the ring is configured for use in a gas turbine engine.
An inner ring for use in a roller bearing, the inner ring comprising:
- an outer wall surrounding an axis;
- two side walls extending away from the outer wall in a direction away from the axis, defining a cavity therebetween for receiving at least one roller, and each of the two side walls having an outer edge at a location facing the cavity and farthest from the outer wall and an inner edge at a location facing the cavity and closest to the outer wall, the outer edge being radially aligned with the inner edge such that the two side walls extend in a direction perpendicular to the outer wall;
- and
- a curved crown extending inward from at least one of the two side walls and configured to contact the at least one roller to reduce wear of the outer edge,
- wherein the inner ring is configured for use in a gas turbine engine.
A roller bearing having an axis, the roller bearing comprising:
- at least one roller;
- an outer ring surrounding an axis;
- and
- an inner ring surrounding the axis, located radially inward from the outer ring, and comprising:
- an outer wall,
- two side walls extending away from the outer wall, defining a cavity therebetween for receiving the at least one roller, and each of the two side walls having an outer edge at a location facing the cavity and farthest from the outer wall and an inner edge at a location facing the cavity and closest to the outer wall, the outer edge being radially aligned with the inner edge such that the two side walls extend in a direction perpendicular to the outer wall, and
- a curved crown extending inward from at least one of the two side walls and configured to contact the at least one roller to reduce wear of the outer edge;
- and
- a cage configured to house the at least one roller between the outer ring and the inner ring,
- wherein the roller bearing is configured for us in a gas turbine engine.
