A steering shaft for a steering system of a motor vehicle, having at least two steering shaft elements, which can be rotated about an axis of rotation, are coupled to one another in a torque-transmitting manner, and are telescopically slidable one inside the other, via which a steering wheel is mechanically connectable to a steering gear of the steering system, wherein at least one of the steering shaft elements has at least two shaft parts, which are formed separately from one another and are connected to one another in a rotationally-fixed manner and which are assembled and connected to one another with at least one separation point, wherein the steering shaft elements are slidable one inside the other beyond the separation point.

There is provided a torque transmission joint configured to transmit torque between end portions of a driving shaft and a driven shaft arranged in series in an axial direction. An outer-diameter-side concave-convex portion is formed on an inner periphery of one shaft of the driving shaft and the driven shaft or a member fixed to the one shaft, an inner-diameter-side concave-convex portion is formed on an outer periphery of the other shaft or a member fixed to the other shaft, and the outer-diameter-side concave-convex portion and the inner-diameter-side concave-convex portion are engaged with a circumferential gap being interposed therebetween. An elastic member is provided between the end portion of the driving shaft and the end portion of the driven shaft either directly or via another member such that torque can be transmitted between the driving shaft and the driven shaft.

Methods and devices for monitoring a drive train for a wind turbine utilize an elastic coupling. The drive train comprises a rotor shaft configured to be driven by a rotor about a main axis, a support structure including a bearing housing surrounding at least one bearing and supporting the rotor shaft for rotation about the main axis to constrain other movements of the rotor shaft. A gearbox input shaft and housing supports the gearbox input shaft for rotation while constraining other movements of the gearbox input shaft. The gearbox input shaft is coupled to the rotor shaft by an elastic coupling that includes a first coupling part rigidly connected with the rotor shaft, a second coupling part rigidly connected with the gearbox input shaft, and elastic elements positioned between the first and the second coupling part to provide a single joint between the rotor shaft and the gearbox input shaft.

Power transmission systems including clutch arrangement and control systems are adapted to be used in numerous different operational environments. Such power transmission systems may include clutch arrangements that provide more effective power transmission capabilities, reduced vibration, greater durability and longer life. Control arrangements are provided to more effectively control and monitor clutch operation in ways that provide for greater system flexibility and drive options. Structures that minimize vibrations may be included in a clutch housing as well as in clutch and separator discs of a disc pack.

A flex coupling assembly for coupling a first shaft to a second shaft of a shaft assembly is provided. The flex coupling assembly decouples axial and torsional stiffness from bending stiffness of the shaft assembly, thereby dampening the transmission of noise and vibration between the first and second shafts. The flex coupling assembly includes an inner housing subassembly and an outer housing subassembly. The inner housing subassembly includes an inner housing and a resilient flex coupling disposed in an outer housing cavity of an outer housing of the outer housing subassembly. A retention member is fixed to an outer housing to retain the inner housing subassembly in the outer housing cavity. The inner and outer housing subassemblies can rotate and translate relative to a common axis, while the inner and the outer housings restrict bending between the inner and outer housing subassemblies, thereby restricting bending between the first and second shafts.
