| 20110048877 | TORSIONAL VIBRATION DAMPER - A torsional vibration damper comprises a housing with a fluid-tight ring-shaped chamber and a vibration ring, which is rotatably supported in the ring-shaped chamber of the housing. Between the vibration ring and the housing, a gap-shaped oil receiving space is formed, which is filled with a viscous damping fluid The oil receiving space has an oil outflow and an oil inflow. The oil drain communicates with a section of the oil receiving space located radially further outside than the oil inflow. The replacement of the damping fluid present in the oil receiving space is thus controlled. This makes it possible to refresh the damping fluid over an operation interval, so that the defined damping properties are maintained during the entire operation period. This helps to increase the life of a torsional rotary damper that is autonomous with reference to the oil supply, or to lengthen maintenance intervals. | 03-03-2011 |
| 20100184520 | RADIALLY ELASTIC COUPLING - A radially elastic coupling comprises several radial braces, each comprising a radially inner end portion and a radially outer end portion, as well as a plurality of jibs bent towards the braces, which in turn each comprise a free end portion and a bound end portion. The inner end portions of the braces are connected to one another. The jibs are each connected with a bound end portion to an outer end portion of a brace. The free end portions of a first group of jibs are formed for connection to a first rotating machine part, whereas the free end portions of a second group of jibs are formed for connection to a second rotating machine part. All the braces and jibs are arranged in a common plane and made of one single piece. Jibs pointing to one another, of adjacent braces are radially interlaced. | 07-22-2010 |
| 20100171248 | TORSIONAL VIBRATION DAMPER OR TORSIONALLY FLEXIBLE COUPLING - A torsional vibration damper or a torsionally flexible coupling comprises an inner part and an outer part that is arranged in ring shape around this inner part, which are joined to one another in a torsionally flexible manner by spring elements, wherein the spring elements subdivide a space formed between the inner part and the outer part into a plurality of successive chambers in the circumferential direction of the damper or the coupling, with these chambers being filled with a viscous medium and connected to one another. There are at least two groups of spring elements which have deflection lines that differ in the circumferential direction. In case of a relative rotation between the inner part and the outer part, owing to differences in deflection lines, there is a strong spatial displacement of the damping medium, so that such a damper or coupling has a high damping potential. | 07-08-2010 |
