摘要： A track roller includes a body having a revolved configuration defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation. A first axial extremity and a second axial extremity are disposed along the axis of rotation. The body of revolution further includes a first rim portion disposed proximate to the first axial extremity, and a second rim portion disposed proximate to the second axial extremity. An outboard track contact surface is disposed axially proximate to the first rim portion, and an inboard slot is disposed axially proximate to the second rim portion.

摘要： An idler assembly includes a cylindrical hub defining an axis of rotation, a radial direction, and a circumferential direction. A stepped circumferential surface of the cylindrical hub has a first radially inner face, and a radially outer cylindrical face. Mounting holes extend radially into the radially outer cylindrical face. A first idler segment is attached to the cylindrical hub, and includes an at least partially flat body having a first planar chain link contacting surface. The cylindrical hub has a first set of metallurgical properties that is different than the second set of metallurgical properties of the first idler segment.

摘要： An idler wheel assembly for a mobile machine is disclosed. The idler wheel assembly may have an idler body defining a cavity between a hub portion and a rim portion. The idler wheel assembly may also have a sound suppression device. The sound suppression device may have a first side plate attached to the idler body and enclosing at least a portion of the cavity to form a closed space, and a second side plate attached to the idler body. The sound suppression device may further have a dampening member disposed between the first side plate and the second side plate, and dampening material positioned inside the closed space and in contact with a surface of an inner portion of the rim portion.

摘要： A track link assembly includes a plurality of link subassemblies including a first link subassembly and a second link subassembly. Each link subassembly includes a pair of links coupled together. Each link includes a first aperture and a second aperture, and the second aperture of each link is C-shaped. The track link assembly also includes a pin element pivotably coupling each of the first link subassembly and the second link subassembly. The pin element includes a centrally positioned central portion and end portions on opposite sides of the central portion. The central portion of the pin element is configured to pass through the first aperture of a first link in each of the first link subassembly and the second link subassembly, and the end portions are configured to pass through the second apertures of a second link in each of the first link subassembly and the second link subassembly.

摘要： A track assembly having a wear monitoring system is disclosed. The track assembly may have a chain assembly including a plurality of track links, a traction assembly including track shoes secured to the plurality of track links, a drive sprocket, an idler assembly including an idler and a mount, and a roller assembly including a plurality of rollers and a roller frame. The wear monitoring system may have a wear sensor configured to generate a signal indicative of a current position of a first component of the track assembly, and a controller in communication with the at least one wear sensor, the controller being configured to determine an amount of wear experienced by the track assembly based on the signal. The first component may be configured such that wear of at least a second component causes the first component to move to the current position from a previous position.
