Bearing assembly and parabolic-trough solar power plant having such a bearing assembly

A parabolic-trough solar power plant comprising at least one solar panel having a shaft part having a longitudinal axis, the shaft part being supported by at least one bearing assembly, wherein the bearing assembly is configured to pivot the solar panel through a pivot angle range about the longitudinal axis wherein the bearing assembly comprises:

• a support element, which includes two vertically extending support sections, wherein a receiving space for receiving the shaft part is formed between the two support sections,
• a chain element that is supported with its two ends in the upper end region of the support section,
• a plurality of roller elements, which are supported in the chain element along its longitudinal extension, wherein the roller elements are supported in the chain element about an axis of rotation parallel to the longitudinal axis, and wherein the roller elements are configured to support a circumferential section of a shaft section of the shaft part,
• wherein the upper ends of the chain element are each attached to the support section by a bearing, and the bearing makes possible a pivoting of the chain element relative to the support section about a compensation axis (b), wherein the compensation axis (b) is disposed horizontal and in projection is perpendicular to the longitudinal axis of the shaft part, and
• wherein the chain element includes a plurality of chain links, and wherein the roller elements are disposed at hinge points between pairs of the chain links.
