Abstract
A cartridge pin assembly in a track chain assembly includes a sleeve bearing having a flared end.
Claims21
A sleeve bearing comprising:
- an at least partially annular cylindrical body defining a cylindrical axis, a radial direction, and a circumferential direction, the at least partially annular cylindrical body including:
- a radially inner circumferential surface;
- a radially outer circumferential surface;
- a first free end and a second free end disposed along the cylindrical axis;
- and
- a flared portion disposed proximate to the first free end along the cylindrical axis, wherein the flared portion includes:
- a radially extending abutment surface,
- a first transitional surface connecting the radially inner circumferential surface to the radially extending abutment surface,
- an angled surface forming an external obtuse angle with the first radially outer circumferential surface,
- a second transitional surface connecting the radially extending abutment surface to the angled surface, and
- a third transitional surface connecting the angled surface to the first radially outer circumferential surface.

A metal sleeve bearing comprising:
- an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction, the at least partially annular body including:
- a radially inner circumferential surface;
- a radially outer circumferential surface;
- a first free end and a second free end along the longitudinal axis opposite the first free end;
- and
- a flared portion proximate to the first free end, wherein the flared portion includes:
- an interface region,
- a first transitional surface connecting the radially inner circumferential surface to the interface region,
- an angled surface forming an external angle with the radially outer circumferential surface,
- a second transitional surface connecting the interface region to the angled surface, and
- a third transitional surface connecting the angled surface to the radially outer circumferential surface.

A sleeve bearing comprising:
- an at least partially annular body including:
- a radially inner circumferential surface;
- a radially outer circumferential surface opposite the radially inner circumferential surface in a radial direction;
- a first free end and a second free end opposite the first free end along a length of the at least partially annular body;
- and
- a flared portion that includes:
- an interface region,
- a first transitional surface connecting the radially inner circumferential surface to the interface region,
- an angled surface forming an external obtuse angle with the radially outer circumferential surface,
- a second transitional surface connecting the interface region to the angled surface, and
- a third transitional surface connecting the angled surface to the radially outer circumferential surface.
