Retainer sleeve for ground engaging tools
First Claim
1. A retainer sleeve configured for use in a retainer system for a ground engaging tool, the retainer sleeve comprising:
- a plurality of plate-like sections, each section being flexibly joined with an adjacent section along either a radially inner edge or a portion of a radially outer edge;
the radially inner edges of the plurality of sections forming part of a segmented inner surface configured for engagement with an outer surface of a locking member of the retainer system, the inner surface extending partially around a central axis of the retainer sleeve to form a substantially C-shaped retainer sleeve having opposite circumferential ends that are spaced from each other;
the radially outer edges of the plurality of sections forming part of a segmented, frustoconical outer surface configured for engagement in an internal lock cavity of a ground engaging tool tip; and
at least one lock detent arm connected at a first, base end to a plate-like section at one of the opposite circumferential ends of the substantially C-shaped retainer sleeve, wherein the at least one lock detent arm includes a detent projection extending from a radially inner surface adjacent a second, distal end of the lock detent arm, the detent projection being configured for engagement with a detent recess formed in the locking member of the retainer system.

Abstract
A retainer sleeve configured for use in a retainer system for a ground engaging tool includes a plurality of plate-like sections, each section being flexibly joined with an adjacent section along either a radially inner edge or a portion of a radially outer edge. The radially inner edges of the plurality of sections form part of a segmented inner surface configured for engagement with an outer surface of a locking member of the retainer system. The inner surface extends partially around a central axis of the retainer sleeve to form a substantially C-shaped retainer sleeve having opposite circumferential ends that are spaced from each other. The radially outer edges of the plurality of sections form part of a segmented, frustoconical outer surface configured for engagement in an internal lock cavity of a ground engaging tool tip.

8. A retainer system for a ground engaging tool, the retainer system comprising:
-
a lock configured to be rotated about a lock rotation axis; and a metal retainer sleeve, wherein the metal retainer sleeve includes; an outer surface configured to mate with a lock cavity of a ground engaging tool tip; an inner surface extending at least partially around the lock rotation axis and being aligned in a direction substantially parallel to the lock rotation axis, and wherein the inner surface is configured to receive the lock rotatably about the lock rotation axis and in a direction substantially parallel to the lock rotation axis; and a plurality of sections joined together along radially inner edges of adjacent sections or along radially outer edges of adjacent sections in an accordion-like arrangement configured such that the metal retainer sleeve is compressible for insertion into the lock cavity, and expandable when the metal retainer sleeve seats inside the lock cavity. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
