Problems solved by technology

[0005] While the system of the '248 patent may retain the wear member on the adapter, it may still be less than ideal
For example, the bolt may not be sufficiently held in place in the center position, which may cause the head of the bolt to move when loading and unloading material from the bucket, thereby increasing the stress on the bolt
Additionally, material that moves past the bolt can accumulate on or around the bolt, which can make removal of the bolt difficult and time consuming
Additionally, bolts may not provide a sufficiently secure attachment in other types of retention systems

Embodiment Construction

[0028] Reference will now be made in detail to exemplary embodiments illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0029] figure 1 Exemplary embodiments of work implements such as machine bucket 10 are illustrated in . In an exemplary embodiment, bucket 10 may be attached to a dragline (not shown) configured to remove material, such as earthy material, with bucket 10 . The dragline may maneuver the bucket 10 by utilizing a lift mechanism (not shown) and a traction mechanism (not shown) controlled by an operator in a nacelle (not shown) of the dragline. Alternatively, bucket 10 may be attached to other types of machines known in the art, such as excavators or other earth-moving machines. As another alternative, the work implement may implement any device for performing the task assigned to the machine.

[0030] The bucket 10 may include a body 12, which may b...

Abstract

A fastener (58) includes a first end and a second end opposite the first end. The fastener also includes an axis (A) extending between the first end and the second end and a head (130) disposed on the first end. The head includes a plurality of radially extending gear teeth (140) disposed on the head around the first end; and a first collar (134) including a tapered surface (136) along the Tapers toward the second end along the axis. The fastener also includes a threaded rod (132) disposed on the second end.

Description

technical field [0001] The present invention relates generally to a holding system, and more particularly, to a system for holding a ground engaging tool connected to a work implement. Background technique [0002] Ground working machines, such as, for example, draglines may be used to dig or split ground or rock and / or move loose material from one place to another. These machines may include buckets for digging or moving material. Buckets can be subject to extreme wear due to the abrasion and impact experienced during earthmoving applications. [0003] The bucket may include a lip including a plurality of noses projecting from a leading edge of the lip. The lip may also include flaps at opposite sides of the lip. Various wear components may be coupled to the lip to protect the leading edge of the lip. For example, the teeth can be mounted to the nose, the lip shields can be mounted between the noses, and the wing shields can be mounted to the wings. The wear part may b...
