| 20100171247 | TORSIONAL VIBRATION DAMPER - A torsional vibration damper comprises an outer housing, an inner part that is concentric relative to the outer housing, a plurality of chambers formed between the outer housing and the inner part, which are filled with a damping medium and are connected to one another through overflow channels, and a plurality of leaf spring assemblies that are arranged in the chambers and join the outer housing and the inner part with one another in a torsionally flexible manner. The leaf spring assemblies have machining-induced deflections. Two leaf springs with substantially similar deflections are each arranged within a chamber. The leaf spring pairs may be arranged in a mirror-image array or in parallel to one another. Thus, the manufacturing cost of a torsional vibration damper can be reduced, while its compact outer dimensions can be maintained. | 07-08-2010 |
| 20090308477 | METHOD FOR MANUFACTURING A HOLLOW SHAFT WITH AT LEAST ONE INTEGRAL FLANGE MADE OF FIBER COMPOSITE - For a method for manufacturing a hollow shaft with at least one integral flange made of fiber composite, a plurality of intersecting windings of fiber material are applied onto a core. Moreover, the core has, for each flange, a radial spreader ring with an axial bearing surface. The windings are laid over an outer circumferential portion of the respective spreader ring and fixed. One or several inserts made of fiber material are inserted in the area of the spreader ring between the windings. The fixing of the wound fiber material is released, but is first still held on the spreader ring. Portions of the windings are then pulled off from the outer circumferential portion of the spreader ring and brought to rest on the axial bearing surface of the spreader ring in order to form a partial portion of a flange. | 12-17-2009 |
| 20080247817 | FORCE-FITTING CLAMPING CONNECTION AND METHOD FOR ITS PRODUCTION - A force-fitting clamping connection comprises a first metal clamping surface, a second metal clamping surface, and a clamping element for clamping the clamping surfaces against one another. The first clamping surface forms a hardened fine surface structure with microreliefs and microdepressions. The second clamping surface has a lower hardness than the first clamping surface. Preferably, the first clamping surface is surface-treated by sand-blasting, shot-blasting or embossing before the hardening operation. This allows permanently high friction values between the clamping surfaces. Also described is a flange connection comprising such a clamping connection for transmitting high torques, and also a production method. | 10-09-2008 |
