A cord package supporting device for supporting a cord package wound with a cord, such as for an elastic joint disk for connecting two shaft portions, is disclosed. The cord package includes two opposite arcuate cord regions and two tangential cord regions that connect the arcuate cord regions to each other and extend parallel to each other. In embodiments, the cord package supporting device includes a first redirecting portion and a second redirecting portion, about which in each case one arcuate cord region of the cord package is guided. In embodiments, the two redirecting portions are integrally connected to each other via a web. An elastic joint disc and a method for producing an elastic joint disc are also disclosed.

A flexible coupling includes a first flange and a second flange, wherein in a relaxed state the first flange and the second flange are each aligned along a longitudinal axis. A plurality of first coupling members extends from the first flange. Each first coupling member includes a first and second driving beam meeting at a first node to form a topologically triangular truss. A plurality of second coupling members extend from the second flange. Each second coupling member includes a first and second driven beam extending from the second flange and meeting at a second node to form a topologically triangular truss. The first node of each of the first coupling members is connected to the second node of a respective one of the second coupling members.

A flexible coupling between two shafts, including a spacer element inserted between the actuating shaft or drive shaft and the actuated shaft or load shaft, and an assembly of articulated connecting rods at both points of connection (between the drive shaft and the spacer element and between same and the load shaft), said articulated connecting rods respectively linking the two elements to be connected, being tangentially arranged in relation to the coupling shaft and angularly spaced around same, a circumferential phase shift of 60, all of the connecting rods on both ends being articulated in ball joints used to facilitate the rotation of the connecting rods in any direction, so that the coupling can adapt itself to all of the potential disalignments that may occur, both radially and axially, or When there is play between the spacer and the load, since, on the opposite side, an axially arranged connecting rod prevents the occurrence of axial play between same.

A disc coupling includes a spacer and discs coupled to opposite ends of the spacer. Each of the discs includes an annular body defining a plurality of circumferentially spaced fastener holes and a plurality of links with each link extending between a pair of the fastener holes. The disc further includes a washer defining a bore aligned with one of the fastener holes. The washer includes one face facing the body and another face facing away from the body and a plurality of surfaces extending between the faces. The surfaces include radially outer and inner surfaces and side surfaces extending between the radially inner and outer surfaces and defining vertices at intersections with the radially inner and outer surfaces.

A power generation device includes: a one-way clutch which is provided between an output shaft of a speed increaser and a drive shaft of a power generator, and which restricts relative rotation of the output shaft and the drive shaft in one direction and permits relative rotation thereof in another direction; and a plurality of elastic coupling members which are provided between the output shaft and the drive shaft, which are spaced in an axial direction, and which absorb misalignment between the output shaft and the drive shaft. The one-way clutch is disposed in a position axially outside an area between the plurality of elastic coupling members.

Described is a rotary coupling that includes a pair of coupling bodies having parallel (preferably coincident) rotation axes, two cylindrical elements and a preload mechanism. A gap is provided between surfaces on the first and second coupling bodies. The first cylindrical element is disposed on the first coupling body and has a first cylinder axis, and the second cylindrical element is disposed on the second coupling body adjacent to the first cylindrical element and has a second cylinder axis that is perpendicular to the first cylinder axis. The preload mechanism imparts a force to each of the first and second coupling bodies and thereby preloads the first and second cylindrical elements against each other at a point of contact. One example of the preload mechanism includes a pair of magnets disposed opposite each other across the gap and another example of the preload mechanism includes an air bearing.
