  • Patent number: 11610440
    Abstract: A method is disclosed, which may include determining a distance of movement of a component of a machine; determining a load factor on the component over the distance of movement; estimating a remaining useful life of at least one of the component, or a wear component associated with the component, based on the distance of movement and the load factor; and performing one or more actions based on the estimated remaining useful life.
    Type: Grant

  • Patent number: 11603642
    Abstract: A pin for a coupler assembly for rotatably coupling a beam of a circle assembly of a grader machine with a bracket of a moldboard assembly of the grader machine includes a body defining a head portion and a shank portion. The shank portion integrally extends from the head portion. The head portion is adapted to be seated over one or more of the beam and the bracket. The shank portion is adapted to pass through the beam and the bracket to rotatably couple the beam and the bracket about the shank portion. A grease gallery is defined through the head portion, extending into the shank portion. The body defines multiple grease passages branching out from the grease gallery up to corresponding sections of an outer surface of the shank portion where the beam and the bracket are correspondingly adapted to lie in rotatable registration with the shank portion.

  • Patent number: 11352762
    Abstract: A coupler assembly for rotatably coupling a moldboard of a grader machine includes a bracket, a beam, a pin, a retainer, and an apparatus. The bracket is adapted to support the moldboard. The beam extends from a circle member rotatably coupled relative to a drawbar of the grader machine. The pin is adapted to rotatably couple the bracket and the beam to each other. Further, the pin defines an end adapted to extend outwardly from an assembly of the bracket and the beam. The retainer is adapted to be engaged with the end to retain the pin with the assembly of the beam and the bracket. Moreover, the retainer defines at least one end portion extending outwardly from the end. The apparatus is adapted to be mounted around the pin at the end to shield the at least one end portion of the retainer extending outwardly from the end.
