Systems and methods for command-driven automatic and semi-automatic mobile wear detection are disclosed. One method may include: transmitting, by a mobile device, a request indicative of a desire to determine a wear metric associated with a part; receiving, by the mobile device, first data associated with the part and indicative of a directive for the mobile device to display an instruction for the mobile device to be situated in a specified position; responsive to a determination, by the mobile device, that the mobile device is situated in the specified position, receiving, by a camera of the mobile device, visual data associated with the part; receiving, by the mobile device, second data indicative of a directive for the mobile device to process the visual data; determining, by the mobile device, the wear metric based, at least, on the processed visual data.

Command-driven automatic and semi-automatic mobile wear detection

A cored wire for hybrid laser cladding includes a hollow metal sheath and a core powder composition. The core powder can include, by weight percent: carbon from about 0.8% to about 1.2%, manganese from about 1% to about 1.4%, silicon from about 0.8% to about 1%, chromium from about 22% to about 30%, titanium from about 0.5% to about 2%, vanadium from about 0.5% to about 2%, boron from about 0.8% to about 1.2%, phosphorus from 0% to about 0.04%, and sulfur from 0% to about 0.03%, the balance of the core powder composition being substantially iron. Components and methods using the cored wire are also disclosed.

Hybrid laser cladding composition and component therefrom

A roller of an undercarriage track system for a machine is disclosed. The roller includes a body and a sensed feature. The body is a solid of revolution formed about a roller axis. The body includes a bore surface and a roller contact surface. The bore surface defines a bore extending through the body. The bore surface is a radially inner surface of the body. The roller contact surface is located outward from the bore surface. The sensed feature is located at the body. The sensed feature is configured to rotate with the body and to be detectable by a sensor.

Track link

Disclosed are various exemplary embodiments of a track joint assembly. In one exemplary embodiment, the track joint assembly may include a first link having a first bore. The track joint assembly may also include a second link having a second bore. Additionally, the track joint assembly may include a pin positioned at least partially within the first bore. The track joint assembly may also include an inner bushing positioned coaxially around the pin, and at least partially within the second bore. In addition, the track joint assembly may include an outer bushing positioned coaxially around the inner bushing. The track joint assembly may also include a seal assembly positioned between the first link and the second link to form a hermetic seal between the first link and the second link.

Track joint assemblies

Systems and methods are disclosed for determining part wear using a mobile device. One such exemplary method includes capturing, using the mobile device, at least one digital image of a wear part of a machine. The method further includes determining, by the mobile device and based on the at least one digital image, a degree of wear of the wear part.

Disclosed are various exemplary embodiments of a track joint assembly. In one exemplary embodiment, the track joint assembly may include a first link having a first bore. The track joint assembly may also include a second link having a second bore. In addition, the track joint assembly may include a solid pin positioned at least partially within the first bore. The track joint assembly may also include a bushing positioned coaxially around the pin. The bushing may include an axial end portion disposed in the second bore. The second link may include a sealing portion surrounding an axial end of the axial end portion. The sealing portion may include material having a different wear resistance than material of another portion of the second link.

Disclosed are various exemplary embodiments of a track joint assembly. In one exemplary embodiment, the track joint assembly may include a first link having a first bore. The track joint assembly may also include a second link having a second bore including first and second portions. The first and second portions may have different diameters. In addition, the track joint assembly may include a solid pin positioned at least partially within the first bore. The track joint may also include a bushing positioned coaxially around the pin. The bushing may include an axial end portion disposed in and contacting the first portion of the second bore. The bushing may also include an axial end-adjacent portion disposed in and contacting the second portion of the second bore. An outer diameter of the end-adjacent portion may be larger than an outer diameter of the end portion.

A roller for a machine undercarriage may include a roller body constructed from a single, unitary piece of parent material. The roller may also include a first roller tread disposed between a first end of the roller body and a second end of the roller body. Additionally, the roller may include a second roller tread disposed between the first and second ends of the roller body.

An idler for a machine undercarriage includes a hub. The idler may also include a body extending radially outward from the hub, the body including a single solid disk with a first substantially planar side and a second substantially planar side opposite the first substantially planar side.

Idler for a machine undercarriage

A cartridge assembly for a track chain is disclosed. The cartridge assembly includes a pin that has a lubricant channel therein. The pin is accommodated in an inner bushing that also has a channel extending therethrough for accommodating the pin. The pin extends beyond either end of the inner bushing. The pin and inner bushing are partially disposed in an outer bushing that also has a channel for accommodating the pin in inner bushing. The ends of the inner bushing and pin extend beyond the ends of the outer bushing. First and second inserts are disposed at either end of the inner bushing. The first and second inserts are disposed between the outer bushing and a pair of opposing collars which are disposed on the ends of the pin beyond the inserts and beyond the ends of the inner bushing. The inserts and collars each include seals. The seals of the collars are supported by one or more thrust rings as opposed to the inserts or partially by the inserts.
