  • Patent number: 11724757
    Abstract: A ground-engaging track system includes a track roller frame, an idler, and anti-backbending rollers supported by the track roller frame at locations between track rollers and the idler. The anti-backbending rollers define an idler space receiving the idler partially therein and positioned to oppose backbending of a deflection-sensitive section of a ground-engaging track.

  • Patent number: 11654983
    Abstract: A sealed and lubricated rotatable track engaging element includes a roller and a roller shaft extending through the roller to support the roller for rotation about a major axis. A first thrust surface is fixed relative to the roller, and a second thrust surface is fixed relative to the roller shaft. A seal cavity extends between the roller and the roller shaft and is formed in part by each of the first thrust surface and the second thrust surface, and a thrust washer stack is within the seal cavity and trapped between the first thrust surface and the second thrust surface. The thrust washer stack includes an inner thrust washer contacting the roller to rotate at a first fractional speed of a speed of rotation of the roller, and an outer thrust washer contacting the inner thrust washer and the collar to rotate at a second fractional speed that is less than the first fractional speed.

  • Patent number: 11396336
    Abstract: A machine track includes a track shoe having a first outboard edge and a second outboard edge, and a first set of pin lugs and a second set of pin lugs. A roller pad is positioned between the sets of pin lugs and includes a roller contact surface extending between a first roller pad end and a second roller pad end. The first roller pad end includes a relatively softer material, and the second roller pad end includes a relatively harder material that forms a trimming edge for trimming off interfering material of an adjacent track shoe in a machine track that is plastically deformed by way of roller contact with the adjacent track shoe during service.
