20090052819 | SPINDLE BEARING DEVICE AND CORRESPONDING BEARING METHOD - The invention relates to a spindle rotor which should be operated without vibrations. The orientation of the figure axis is accepted and the anchoring of the rotor bearing (SL) is configured such that the orientation of the geometric rotational axis adapts to the physical main axis of inertia. It is possible to produce said bearing in the form of an actively controlled bearing, whereby the orientation is measured and is dynamically carried out, but also in the form of bearing comprising passive elements which are associated with the external ring of the bearing and enable a correspondingly dynamic orientation of the bearing. Said device can also comprise a special damper (T) which dampens the vibrations of the bearing (SL). | 02-26-2009 |

20090309454 | PIEZOELECTRIC ACTUATOR - A piezo actuator includes an adaptation element, which is configured to adapt the piezo actuator to a controller for inductive loads, particularly to a converter for actuating inductive loads. The adaptation element allows use of controllers or converters of numerical control systems, which normally are used for actuating servo motors. Therefore it is no longer necessary to provide specially designed hardware for the actuation of piezo actuators, but instead the above-mentioned controllers can be used. Furthermore, as a result of the adaptation element, the piezo actuators can be integrated in the bus of the numerical control system. This allows communication in real time via the NC bus. | 12-17-2009 |

20130081914 | ACTIVE OSCILLATION DAMPER WITHOUT DIRECT ACCELERATION DETECTION - An active oscillation damper has a balancing mass which is movable relative to an oscillating mechanical structure. The control device then determines a compensation movement for the balancing mass based on a determined three-dimensional absolute motion of the mechanical structure. A balancing drive, arranged on the mechanical structure and acting on the balancing mass, is activated by the control device. The balancing mass is displaced by the balancing drive relative to the mechanical structure commensurate with the determined compensation movement. The measured values supplied to the control device include actual values of the balancing drive and/or a position of the balancing mass relative to the mechanical structure and/or at least one derivative with respect to time of the position of the balancing mass relative to the mechanical structure. The three-dimensional absolute motion of the mechanical structure is determined by the control device from the aforementioned values. | 04-04-2013 |
20130085607 | PROCESSING MACHINE WITH VIBRATION COMPENSATION OF MOVABLE MECHANICAL STRUCTURES - A control device of a processing machine actuates an axle drive of the processing machine commensurate with a reference displacement movement, displacing a mechanical structure of the processing machine accordingly. The control device determines an absolute movement of the mechanical structure in space and therefrom, taking into account the reference displacement movement of the mechanical structure, a compensation movement for a compensating mass damping a vibration of the mechanical structure. Arranged on the mechanical structure is a compensating drive which acts on the compensating mass. The control device actuates the compensating drive in accordance with the compensation movement, displacing the compensating mass relative to the mechanical structure and thereby damping the vibration of the mechanical structure. | 04-04-2013 |
20130085617 | VELOCITY-PROPORTIONAL ACTIVE VIBRATION DAMPING - An active vibration damper has a damping device arranged on a vibration-susceptible mechanical structure. A force can be injected directly into the vibration-susceptible mechanical structure with the damping device. A damping force which damps a vibration of the mechanical structure is determined by a control device of the active vibration damper with reference to an absolute movement of the mechanical structure in space. A damping drive of the damping device which is arranged on the mechanical structure is activated by the control device in accordance with the determined damping force such that the determined damping force is injected into the mechanical structure with the damping drive. The control device determines the damping force such that the damping force is proportional at all times to the instantaneous velocity of the mechanical structure. | 04-04-2013 |
