摘要:
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.

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,
摘要:
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.
摘要:
An elastomeric bushing for a bearing. The bushing can, even after installation in the bearing, be pretensioned or calibrated, by displacement of elastomeric material in the interior of the bushing, where the displacement is carried out by different pressing mechanism and tensioning mechanism in the bushing and/or in the surrounding bearing.
摘要:
Elastomer components, which are to have an elastomer volume with a sufficiently large prestress, as is required, for example, for use in wind energy plants. The elastomer components are substantially based on the incorporation and integration of separating elements into the elastomer body of the component, the elements are disposed either individually or in structures. The body may be compressed by pressure supplied into the region, between the separating elements and the surrounding elastomer material, or directly into the separating elements, such that the elastomer components are prestressed in a dynamically adjustable manner.

摘要:
A clamping bushing which, due to the particular eccentric geometry and composite materials used to manufacture the same, comprising elastomers (14, 15) and metal sheets (10, 11), is suitable for the reduction of principally vertically acting vibrations and structure-borne sound which can arise in machines/gearboxes and, in particular, in wind turbines.
摘要:
An elastic bushing which has novel damping by corresponding design measures and devices in order to eliminate, or greatly reduce, undesired vibrations in planetary bearings, particularly for planet gears for planetary gearboxes. This invention also relates, in particular, to the use of bushings, planet gears or planetary gearboxes of this type in machine parts and installations which transmit only low or no moments such, for example, wind turbines.
