The invention relates to a compensating bearing in which a substructure and a superstructure are displaceably connected to each other by means of a sliding bearing, whereby said displacement occurs in a linear and/or cardanic manner in one of the directions X, Y and Z. The inventive bearing is characterized in that a carriage (7) that is connected to a cover plate (10) is guided in a linear manner in the direction of X and/or Y by two interspaced shafts (5, 4) on which displaceable slide bushings (9, 8) are arranged and/or the cover plate can be guided in a tiltable manner by a pivoting bearing (18) in the direction of Z. This combination of a linear and pivoting bearing enables all alignment errors arising as a result of finishing inaccuracies, foundation subsidence, desired and undesirable slanting to be compensated and regulates the variations in lengths due to temperature and load. |
