Abstract
A retainer sleeve includes an at least partially annular body defining an axis of rotation, a radial direction, and a circumferential direction. The body may also have a radially inner annular surface defining a radially inner aperture, and a first anti-rotation feature extending radially inwardly from the radially inner annular surface including a sloping ledge having a locking surface that faces at least partially in the circumferential direction and along a direction that is parallel to the axis of rotation, forming an oblique angle with the direction that is parallel to the axis of rotation.
Claims19
A retainer sleeve comprising:
- a body including
- an at least partially annular configuration defining an axis of rotation, a radial direction, a circumferential direction, a first axial end disposed along the axis of rotation, and a second axial end disposed along the axis of rotation;
- a radially inner annular surface defining a radially inner aperture;
- a detent feature including a rib extending radially inwardly from the radially inner annular surface, defining a rib radial height;
- and
- a lip disposed at the first axial end extending radially and circumferentially past the rib.
A retainer sleeve comprising:
- a body including an at least partially annular configuration defining an axis of rotation, a first axial end, and a second axial end;
- the body further including a radially inner annular surface defining a radially inner aperture, a first circumferential end, and a second circumferential end;
- the body further including a detent feature including a rib extending axially and radially inwardly from the radially inner annular surface at a location that is proximate to the first circumferential end, and a lip disposed at the first axial end and extending in a circumferential direction of the rib and the second circumferential end.
