    摘要: A track link rail surface and roller interface includes a first roller including a cylindrical configuration defining a radial direction, a longitudinal axis, a circumferential direction, and a plane containing the radial direction and the longitudinal axis. The first roller includes a first track link rail engaging surface including a first concave arcuate surface defining a first concave radius of curvature. The interface includes a first track link including a first track link rail surface including a first convex arcuate surface defining a first convex radius of curvature that is less or equal to the first concave radius of curvature.

    摘要: A clamping master track link includes a body that defines a first bore and a second bore, a first aperture disposed between the first bore and the second bore, a second aperture disposed between the first aperture and the second bore, a first strut with a first gap disposed between the first aperture and the second aperture, a second strut with a second gap disposed between the first aperture and the first bore, and a bridge disposed between the second aperture and the second bore. The first bore defines a cylindrical bore surface that is at least partially textured.
