Abstract
Abstract A vibration damping adjustable support for machines. A base plate supports elastically a machine. A bearing element is disposed below the base plate for supporting the base plate and an adjustment device is provided for changing the supporting condition of the bearing element. A regulating provision is furnished for effecting a change in the support conditions for a shafting arrangement of an elastically supported machine by way of changing the supporting forces. Depending on the deviations from a set point value found with a surveying measurement device the supporting force of spring bodies disposed below the base plate are changed until the set point is reached again. In this manner relatively small deformations of foundations of the base plate can be achieved by way of relatively large adjustment distances at the elastic supporting element for aligning and realigning of shafting arrangements.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
154 words
A method for alignment of shafts disposed on an elastic or flexible base plate comprising sensing continuously the quietness of the running of a shafting arrangement of a machine positioned on the base plate supported by way of a spring element requiring a support force; ascertaining the state of the solid connection between bearing element and base plate with a measurement device; determining the state and size of support force changes in the spring element; resetting a hydraulic adjustment device incorporated into the spring element for the support force of the spring element disposed below the base plate depending on deviations from a set point observed by the sensing until the set point has been reached again and for changing the support conditions of the base plate; disengaging an existing solid connection between the base plate and the spring element for the resetting process; setting the adjustable element; and providing again said solid connection.
Claim 2
Independent Claim
154 words
A method for alignment of shafts disposed on an elastic or flexible base plate comprising sensing continuously the quietness of the running of a shafting arrangement of a machine positioned on the base plate supported by way of a spring element requiring a support force; ascertaining the state of the solid connection between bearing element and base plate with a measurement device; determining the state and size of support force changes in the spring element; resetting a hydraulic adjustment device incorporated into the spring element for the support force of the spring element disposed below the base plate depending on deviations from a set point observed by the sensing until the set point has been reached again and for changing the support conditions of the base plate; disengaging an existing solid connection between the base plate and the spring element for the resetting process; setting the adjustable element; and providing again said solid connection.
