Abstract:
A track roller assembly is disclosed. The track roller assembly may include a shaft and a cap engaged with the shaft. The track roller assembly may further include a roller shell configured to rotate about the shaft and may have a through-bore. The track roller assembly may include a crescent-based track roller seal, a toric-based track roller seal or a combination of both the crescent-based track roller seal and the toric-based track roller seal.
Abstract:
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.
Abstract:
A roller collar is provided in a roller assembly of a machine, such as a track carrier roller of a track-type undercarriage. The roller assembly includes a roller mounted on a shaft and having a seal retaining lubricant between the roller and the shaft. The collar and an inner surface of the roller form a seal cavity placing the seal in fluid communication with an ambient atmosphere surrounding the roller. The roller collar extends over an opening into the seal cavity, such as with an outwardly extending flange or teeth or with an outer surface configured to increase a distance to be traveled to enter the seal cavity, and to reduce the amount of abrasive material entering the seal cavity and potentially compromising the integrity of the seal.
Abstract:
An example track assembly in accordance with the present disclosure may include a pin, a bushing, a link, and a seal. The pin may define an axis, and may include opposing ends. The bushing may be positioned about the pin, and may include opposing ends. The link may have an inner face extending radially from the axis and defined by at least three portions. The three portions may include a recessed portion disposed between two non-recessed portions. The recessed portion may have a recessed face. The seal may be disposed at least partially within the recessed portion of the link. The seal may engage the recessed face of the link and may engage an end of the bushing such that a gap exists between the inner face of the link and the end of the bushing.

Abstract:
System and methods for determining wear of a rotational component of an undercarriage for a machine are disclosed. One method includes determining a rotational speed of a drive sprocket of the undercarriage, determining a rotational speed of the rotational component, determining a size parameter of the rotational component based on at least the determined rotational speed of the drive sprocket and the determined rotational speed of the rotational component, and determining the wear of the rotational component based on the determined size parameter of the rotational component.
Abstract:
A method of reducing noise on an idler wheel of a track type tractor is provided. The idler wheel includes a tread surface and a retaining surface on an outer periphery. The method includes machining the tread surface to a depth less than a predefined tolerance limit. The method further includes forming a metal mesh on the tread surface wherein the metal mesh is structured to define space between the tread surface and metal mesh to form a three dimensional structure. The method includes filling the space between the three dimensional structure and the tread surface with a noise reducing material to a predefined height.

A seal packing guard is provided in a roller assembly of a machine, such as a track carrier roller of a track-type undercarriage. The roller assembly includes a roller mounted on a shaft and having a seal retaining lubricant between the roller and the shaft. A collar and an inner surface of the roller form a seal cavity placing the seal in fluid communication with an ambient atmosphere surrounding the roller. The seal packing guard is attached to an outward surface of the roller and extends over an opening into the seal cavity to reduce the amount of abrasive material entering the seal cavity and potentially compromising the integrity of the seal.
