Device for compensating for unevenness of the supporting surfaces and/or for load distribution or load monitoring on a live ring

摘要

Device on a live ring arranged between a supporting surface of a rotatable top part of a piece of equipment and a supporting surface of a fixed bottom part of the piece of equipment, the device being intended for the compensation of unevenness of the supporting surfaces due to manufacture and/or load and/or for load distribution, load monitoring and/or safeguarding against overload. The device consists of at least one hydraulic tension and/or compression element, which is arranged in the region of the maximum one-sided loading of the live ring, is preferably designed as a hydraulic pressure cushion and is arranged uniformly as a plurality of units around the circumference of the live ring. Each tension and compression element is connected to a pressure-measuring and control device in order to bring the elements to the same pressure for the compensation of unevenness and to be able to apply different pressures for the equalisation of the load distribution, for load monitoring and for safeguarding against overload.
