  • Patent number: 10023251
    Abstract: A track roller assembly may have a track roller, a roller shaft and collars press fit onto either end of the roller shaft to retain the track roller on the roller shaft with an axial clearance between the collars and the track roller. During assembly, the collars may be press fit onto the shaft ends and forced axially inwardly until further axial movement of the collars is prevented by engagement shoulders of the track roller. A compressive axial load may be applied to the roller shaft to reduce a shaft length of the roller shaft and to cause the roller shaft to slide inwardly relative to the collars. The compressive axial load is removed from the roller shaft so that the roller shaft extends back to the normal shaft length and the collars move axially farther apart as the roller shaft extends back to the normal shaft length.

  • Publication number: 20170356164
    Abstract: An ID tag is disposed on a plurality of components of a machine. A controller stores a usage threshold for each component, receives signals from an ID tag reader, and associates an identification number from each ID tag with a component of the machine. The controller determines previous usage data for each component, determines an extent of usage of the machine since generation of the previous usage data, determines current usage data for each component based upon the extent of usage of the machine and the previous usage data, and compares the current usage data for each component to the usage threshold for each component. The controller generates an alert for each component in which the current usage data for that component exceeds its usage threshold and transmits the alert to a system remote from the machine.

  • Patent number: 9073589
    Abstract: The present disclosure is directed to a pin joint component for a pin joint assembly that has improved wear surfaces, especially for those portions of the pin joint component surface that interface thrust rings, lips, and other adjacent wear components. The pin joint component comprises a first treated region that is formed by removing material from the wear surface of the pin joint component and replaced with clad material. Prior to this operation, a second treated region is formed by removing material from a section of the pin joint component distinct from the first treated region and performing a nitriding process thereon.
