  • Patent number: 8746663
    Abstract: A mechanically adjustable elastomer bearing based on a correspondingly arranged spring element whose spring stiffness can be adjusted or pretensioned individually by deformable elastomer bodies or elastomer layers. The deformation of the elastomer layers, and thus of the spring elements, is achieved by a pressure-generated device which is fully integrated into the spring element. The elastomer bearing are particularly suitable for use as bearings in rotor and gearbox for large wind turbines, but can also advantageously be employed in machine and vehicle construction, and in particular package clutches.

  • Patent number: 7906191
    Abstract: Construction and advantages of improved wavy composite structures made from wavy composite, unidirectional composites, and damping materials is revealed. By combining wavy composite laminae in various waveforms, offsets, angular orientations and material combinations, it is possible to provide axial, torsion, or shear properties equivalent to unidirectional materials but without the limitations related to fiber discontinuity, labor costs for fabrication, and weakness at seams where laminates overlap. By combining wavy composite layers with unidirectional crossplies, or by using woven mats with various fill fiber levels where the warp fibers are sinuously arranged, improved strength and damping is possible. Several examples of both wavy crossply laminates and unidirectional crossply laminates are analyzed and compared.
