  • Publication number: 20240110601
    Abstract: The invention relates to machine components which are intended preferably for drive trains for driven installations and have the function of a cardanically flexible coupling with simultaneously high torsional stiffness, and are capable of absorbing high forces acting axially on the installation. The particular functionality of these couplings is achieved in particular through the use of specially equipped and oriented hydraulic springs. The invention relates in particular to drive trains for wind turbines, which are equipped with a corresponding coupling according to the invention, in order to divert and distribute in particular high axial forces.

  • Publication number: 20230296155
    Abstract: The invention relates to a tuned mass damper or vibration damper which, with the aid of an assembly (2) of a plurality of stacked, specially shaped or bent leaf springs (2.1), can be adapted over a certain range to the disturbance frequencies acting on a component to be damped or of the vibration system to be damped, the position of the damper mass (1, 34) being changed essentially only slightly. The invention relates in particular to one- and two-dimensionally effective tuned mass dampers. The tuned mass dampers according to the invention are suitable in particular for installations, vehicles and machines that undergo frequent changes in rotational speed, resulting frequently in disturbance frequencies that become noticeable, in particular, in the form of structure-borne sound, or other vibrations.

  • Patent number: 11761502
    Abstract: Novel elastic torsion stop components based on multilayer elastomer metal elements in cylindrical, conical, or spherical shape. The elastic torsion stop components are particularly suitable for use as maintenance-free and low-wear joints having a large angular spread, for example in vibration absorbers, such as in pendulum vibration absorbers for wind turbines.

  • Patent number: 11732690
    Abstract: A new type of independently damping pendulum suspension for pendulum dampers for use in tall slender constructions and technical installations, more particularly used in wind turbines. A Cardan joint is equipped with damping elements and mounted at the other end opposite the pendulum mass. The Cardan joint is able, despite the small motions, to sufficiently damp the oscillations of the pendulum produced by disturbing frequencies.

  • Patent number: 11603821
    Abstract: A novel rotation vibration damper and to vibration absorbers having the damper for wind turbines or other high and, relative to the height thereof, narrow installations or buildings. The disclosure particularly relates to vibration absorbers comprising at least one oscillating mass on a pendulum cable or pendulum rod, wherein the mass is caused to vibrate by an excitation frequency which can be damped by a rotation damper and, in particular, a rotating eddy current magnet damper which forms part of the absorber.

  • Publication number: 20230062968
    Abstract: The invention relates to a new type of tuned mass damper which is suitable in particular for damping oscillations of a low frequency, and can thus be used preferably as a construction damper when building or siting high, narrow structures, such as wind-turbine towers. The invention relates in particular to a pendulum oscillation damper having a first pendulum, to which the mass is attached, and a second pendulum, which is formed by a spring-like support device of a different design and is operated using a gas-air volume such that, with the aid thereof, the frequency of the oscillation system can be adapted and adjusted.

  • Patent number: 11255409
    Abstract: A vibration absorber which, in addition to a main mass which is fixed thereto and moved along a curved trajectory by a driving mechanism, comprises a substantially smaller variably adjustable rotating flywheel mass which is moved together with the main mass along the trajectory thereof, enabling the adjustment of the frequency of the absorber. The rotating flywheel mass is driven by a novel belt device independently of the driving mechanism. A rotating vibration absorber which, along with the main mass and the rotating flywheel mass, comprises its own damping unit, such as an eddy-current damping unit.

  • Patent number: 10718232
    Abstract: A vibration absorber which, in the broadest sense, is based on a pendulum device for dampening undesirable vibrations which occur in a very slender structure, such as a wind turbine. The undesirable vibrations are caused by an acting force, in particular wind force. The invention thereby relates to vibration absorbers in which the pendulum mass can be temporarily stopped or braked, either entirely or partially, by an electromagnetic brake. The power supply or the current regulation of the electromagnetic brake correspondingly controls the braking function of the electromagnetic brake.

  • Patent number: 10711859
    Abstract: A novel vibration absorber for damping vibrations of a building or a machine installation having an inherent frequency of preferably below 1 Hz, preferably below 0.5 Hz, in particular, <0.25 Hz, as may occur, for example, in wind turbines or also other tall slim buildings or installations. The vibration absorber which, besides a main mass which is fixed per se and is moved along a track analogous or similar to a pendulum mass, has a substantially smaller, variably adjustable rotating flywheel mass, which can be moved with the main mass on the track thereof and with the aid of which the frequency of the absorber can be finely adjusted or adapted.

  • Patent number: 10619657
    Abstract: Workpieces that generate pressure by an extrusion media (6, 6a) and are deformed in this way for the secure connection of components (7, 8). In particular, an extrusion billet which comprises an extrudable material or material mixture in the interior thereof, which can be reversibly compressed by a compression die (4) penetrating into the material, such that billet can expand in diameter by increasing the internal pressure in the billet, which leads to a very secure, but reversible press fitting of the different types of components to be connected, in particular of shaft-hub connections for mechanical engineering.
