Abstract: An automatic lubrication system for automatic and demand-driven charging of a bearing with a lubricant includes an automatic lubrication device configured to automatically charge the bearing with the lubricant, a detecting device configured to detect at least one operating parameter of the bearing, and a data-transmission device that is configured to transmit data from the detecting device to the lubrication device. The automatic lubrication device is configured to charge the bearing with the lubricant based on the operating parameters detected by the detecting device.

Abstract: The invention resides in an assembly for rotationally supporting a wind turbine blade (110) relative to a wind turbine hub (120). The assembly comprises an intermediate ring (130) having an inner annular portion and an outer annular portion provided with means for attaching the turbine blade. The intermediate ring is rotatably mounted to the hub via a first bearing arrangement. According to the invention, the first bearing arrangement comprises a radial bearing (140) and a thrust bearing, whereby the inner annular portion is mounted to the hub via the radial bearing and the outer annular portion is mounted to the hub via the thrust bearing. The thrust bearing is a plain bearing comprising first and second sliding surfaces (151, 152) which are clamped to the hub between first and second clamping members (161, 162).
