Abstract: A torsional vibration damper or rotationally elastic coupling comprises: an outer housing including a flange; an inner part arranged within and rotatable relative to the outer housing; a plurality of intermediate pieces arranged around the inner part and spaced apart from each other in circumferential direction so as to form a plurality of chambers filled with a damping medium; a plurality of leaf spring assemblies having one or more leaf springs, said leaf spring assemblies being arranged in said chambers and having outer end portions engaging with receptacles formed between neighbouring intermediate pieces and inner end portions engaging with the inner part; and a clamping ring extending around the intermediate pieces and the leaf spring assemblies for securing the leaf spring assemblies between the intermediate pieces.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A membrane compensating coupling comprises a first compensating element made of fiber composite material with two membranes located opposite one another, a second compensating element and an intermediate tube inserted between these. The first and second compensating element in each case have on their side pointing towards the intermediate tube a radially inwardly directed connecting flange. The intermediate tube is releasably coupled to the connecting flanges. As a result, a membrane compensating coupling comprising at least two membranes made of fiber composite material is provided, which is easy to produce and install, at the same time has low inertias and allows large angle, radial and axial compensation and also a flexible axial length. A hole anchor connection which is particularly suitable for such couplings is also described.

Abstract: 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.

Abstract: 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.
