Abstract: A heavy earth-moving machine having a lower structure and an upper structure rotatably supported by the lower structure for rotation about an axis. A substantially circular lower rail is mounted on the lower structure and includes an inclined lower surface. A substantially circular upper rail is mounted on the upper structure and includes a substantially planar upper surface that is oriented substantially perpendicular to the axis. Tapered rollers support the upper rail above the lower rail for rotation of the upper rail about the axis. Each roller engages both the upper surface and the lower surface and defines and rotates about a roller axis that intersects the axis at a non-perpendicular angle.

Abstract: A roller circle assembly for heavy machinery includes an upper circular rail and a lower circular rail concentrically arranged about a central axis, and tapered rollers between the upper and lower rail. Each tapered roller includes a flange having an angled and convex flange contact surface that contacts the lower rail. The lower rail and/or the upper rail can include an angled surface configured for contact with the flange contact surface. The geometry of the rollers and the lower rail are configured to reduce the stresses applied to the rollers and lower rail due to contact between the flange contact surface and the angled surface.
