Abstract
A cup bearing includes a cylindrical component having first and second axial ends and defining a lumen therethrough. The cylindrical component includes first and second end portions proximal to the first and second axial ends, respectively. The cylindrical component includes a corrugated portion disposed axially between the first and second end portions. The corrugated portion includes a plurality of corrugations extending radially inwardly. A corrugation of the plurality of corrugations includes a ridge defining a first inner radius of the lumen. The cup bearing further includes a first radial stop associated with the first end portion. The first radial stop defines a second inner radius greater than the first inner radius. The cup bearing also includes an end cap coupled to the second axial end of the cylindrical component.
Claims24
A cup bearing comprising:
- a cylindrical component having first and second axial ends and defining a lumen therethrough, the cylindrical component including first and second end portions proximal to the first and second axial ends, respectively, the cylindrical component including a corrugated portion disposed axially between the first and second end portions, the corrugated portion including a plurality of corrugations extending radially inwardly, a corrugation of the plurality of corrugations including a ridge defining a first inner radius of the lumen;
- a first radial stop associated with the first end portion, the first radial stop defining a second inner radius greater than the first inner radius;
- and
- an end cap coupled to the second axial end of the cylindrical component.
A method of forming a cup bearing, the method comprising:
- cutting a sheet material to form a blank;
- corrugating a portion of the blank to form a plurality of corrugations;
- shaping the blank into a cylindrical component having first and second axial ends and defining a lumen, the plurality of corrugations projecting radially inwardly toward an axis of the cylindrical component;
- and
- coupling an end cap to an axial end of the cylindrical component.
A cup bearing comprising:
- a component having first and second axial ends and defining a lumen therethrough, the component including first end portion proximal to the first axial end and including a plurality of tines at a second axial end, the plurality of tines extending radially inwardly over the second axial end, a corrugated portion disposed axially between the first and second axial ends, the corrugated portion including a plurality of corrugations extending radially inwardly, a corrugation of the plurality of corrugations including a ridge defining a first inner radius of the lumen;
- and
- a first radial stop associated with the first end portion, the first radial stop defining a second inner radius greater than the first inner radius.
