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 and retainer sleeve assembly comprising:
- a retainer including
- a drive portion, and
- a lug receiving portion defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall, and including a skirt that at least partially defines the first sidewall, second sidewall, and catch surface, the skirt terminating at a sloped face that intersects with the first sidewall;
- and
- a retainer sleeve including
- a body including
- an at least partially annular configuration defining an axis of rotation, a radial direction, and a circumferential direction;
- 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 is at least partially complementarily shaped to engage the sloped face of the skirt of the retainer.
