摘要： A fastener retaining component may comprise a first elongated member. A length of the first elongated member may be greater than a diameter of a fastener receiving element of a component. The fastener retaining component may further comprise a second elongated member. A length of the second elongated member may be greater than the diameter of the fastener receiving element. The fastener retaining component may be configured to be press-fit within the fastener receiving element such that press-fitting the fastener retaining component, within the fastener receiving element, increases a tension in the fastener retaining component to cause the first elongated member and the second elongated member to engage with an inner surface of the fastener receiving element and to retain a fastener within the fastener receiving element.

摘要： A cutting edge component for a work tool on an earth-moving machine may include a longitudinally-extending wear component and a support surface connectable to a moldboard of the earth-moving machine. The wear component may include at least one wear portion connected to the support surface, and the at least one wear portion may form at least one ground engaging edge. The at least one wear portion may include a mild steel body and a plurality of longitudinally-spaced white cast iron teeth vacuum brazed along a distal, ground engaging edge of the mild steel body. The plurality of teeth may each be shaped with two intersecting substantially planar surfaces arranged to mate with at least a surface extending between the distal, ground engaging edge and at least one of a rearward-facing surface of the mild steel body and a front-facing surface of the mild steel body on at least one of a side of the mild steel body facing away from a direction of travel of the machine and a side of the mild steel body facing in the direction of travel of the machine to form a brazed joint. Each tooth may include a material directing feature defined in a front-facing surface of each tooth when the tooth is brazed to the mild steel body.

摘要： A tool erosion detecting system for a machine having a ground engaging tool is disclosed. The tool erosion detecting system may include a camera configured to generate a first image of the ground engaging tool on a display device, an input device configured to receive a user input, and a controller in communication with the camera and the input device. The controller may be configured to generate an augmented reality view of the ground engaging tool. The augmented reality view may include the first image of the ground engaging tool generated by the camera and a second image of a ground engaging tool superimposed on the first image and being associated with a selected wear level, wherein the selected wear level is based on the user input.

摘要： A wear component for a ground engaging tool includes a mounting portion having a first surface, a second surface, and a thickness between the first surface and the second surface. The mounting portion is connectable to a mounting assembly of the ground engaging tool. The wear component also includes at least one wear portion connected to the mounting portion and forming at least one ground engaging edge. The at least one wear portion has at least one first surface including at least one groove extending from the at least one ground engaging edge toward the mounting portion, at least one second surface, and at least one thickness between the at least one first surface and the at least one second surface. A maximum of the at least one thickness of the at least one wear portion is larger than a maximum of the thickness of the mounting portion.
