Ground engaging tool locking system
A ground engaging tool locking system includes a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis. The pin includes a groove located between the first, proximal head region and the second, distal end region. A biasing element is disposed at least partially within the groove.
Retainer sleeve design with anti-rotation features
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.
Damper structure
Disclosed is a damper structure in contact with a connection unit for coupling a first coupling structure part and a second coupling structure part, including a damper part formed of an elastic material and at least one fixing part coupled to at least one surface of the damper part and protruding outward, and coming into contact with the connection unit and moving toward the damper part by pressure applied by the connection unit when the connection unit is separated or fastened.
Retention system for ripper tips
A work tool or a wear member includes a working portion or a wear portion, a hollow portion that further defines a lock receiving aperture defining an axis of rotation, a radial direction, and a circumferential direction. The axis of rotation is transverse to the direction of assembly of work tool or wear member as the member is slid over a nose portion of a tool adaptor or the like. The axis of rotation is spaced away from the direction the pin receiving thru-hole extends a predetermined distance measured along the direction of assembly.
DAMPER STRUCTURE
Disclosed is a damper structure in contact with a connection unit for coupling a first coupling structure part and a second coupling structure part, including a damper part formed of an elastic material and at least one fixing part coupled to at least one surface of the damper part and protruding outward, and coming into contact with the connection unit and moving toward the damper part by pressure applied by the connection unit when the connection unit is separated or fastened.
RETAINER SLEEVE WITH AN ANTI-ROTATION FEATURE
In some implementations, a retainer sleeve may include a body including an at least partially annular configuration defining a retainer axis. The body may include an inner surface configured to rotatably receive an outer surface of a lock. The body may include a plurality of plates circumferentially joined together with respect to the retainer axis, where a first plate of the plurality of plates includes a first leg joined to the first plate extending away from the retainer axis and configured to contact a lock cavity of the lock. The body may include an anti-rotation feature, disposed on the first plate, extending inward from the inner surface toward the retainer axis, the anti-rotation feature including a locking surface configured to contact a lock skirt of the lock, the locking surface disposed at a first angle with respect to a bottom end of the first plate.
WEAR COMPONENT SECUREMENT
A wear component securement system can include a housing securable against rotation relative to a wear component, a pin rotatable in a passage of the housing about an axis of rotation, the pin being configured to displace along the axis of rotation in response to rotation of the pin in the passage, and a resilient member that resists rotation of the pin away from a locked position relative to the housing. A method can include installing a housing, a pin received in the housing, and a resilient member that resists rotation of the pin, the installing including preventing rotation of the housing relative to the wear component, and rotating the pin to a locked position, thereby aligning at least one bearing surface of the pin with at least one bearing surface of the wear component.
GROUND ENGAGING TOOL ATTACHMENT ARRANGEMENT
Provided is an arrangement that attaches a ground-engaging tool (GET) to an adapter on support structure of ground/earth engaging/conditioning apparatus. A retainer is in a recess of the adapter. A fastener is received through the GET aperture and into the adapter aperture. The head of the fastener can be within a recess of the GET. The recess can be multi lobed/shaped to receive the retainer and prevent rotation or other torsional/lateral deformation of the retainer when tightening/inserting the fastener. A fastener has a first threaded portion adjacent the head of the fastener and a second threaded portion along a shaft portion of the fastener extending distal from the head. The first threaded portion can be wider and/or of a more coarse thread pitch than the second threaded portion.
WEAR ASSEMBLY
A wear assembly for earth working equipment including a wear member including an exterior surface, an opening to receive a separable component, and a hole extending from the external surface to the opening. A lock in the hole to secure the separable component to the wear member, wherein the lock includes a collar and a pin that is adjustable within the collar so that the pin is movable inward to retain the separable component and movable outward to release the separable component. A magnet to secure the collar in the hole. The lock may pivot outwardly into the hole.
LOCK ASSEMBLY FOR GROUND ENGAGING TOOL
A locking assembly for locking a ground engaging tool such as a shroud to a bucket lip. The bucket lip has a C-shaped boss fixed thereto. The ground engaging tool has a recess to receive a lock, the recess having an opening which is shorter in axial length than the recess. The lock is arranged to pivot about the boss as the ground engaging tool is slid rearwardly relative to the bucket lip. When the lock is located entirely within the recess, it can be accessed through a rear tunnel and tightened to hold the assembly in place.
