Bearing device and solar power plant unit using the same

摘要

A bearing device for a solar power plant unit includes at least one support element, at least one first roller and at least one second roller. At least one first roller bearing unit is movably supported on the support element and rotatably supports the at least one first roller and the one second roller. At least one first spherical plain bearing having an outer ring is attached to the at least one first roller. A solar power plant includes at least one mirror movably supported by at least one such bearing device.

主权项

1. A bearing device for a solar power plant unit, comprising:
a support element, a first roller bearing unit movably supported on the support element, a first roller and a second roller disposed on the first roller bearing unit, the first roller bearing unit supporting the first and second rollers at two points along a circumference lying within a plane, the first roller comprising a first spherical plain bearing such that the first roller is attached to an outer ring of the first spherical plain bearing, an inner ring of the first spherical plain bearing being attached to the first roller bearing unit via a bolt which defines an axial direction that is planar perpendicular to the plane within which the circumference lies, the inner ring of the first spherical plain bearing having an outer surface which is convex, the outer ring of the first spherical plain bearing having an axis of rotation and an inner surface that is configured to slidingly contact the outer surface of the inner ring of the first spherical plain bearing such that the axis of rotation of the outer ring is tiltable relative to the axial direction of the bolt such that the bearing device is configured to have the outer ring that is axially tiltable relative to the support element.
