Abstract

The invention relates to a shaft with length compensation, comprising an anti-friction bearing between the first and the second axial element, which is arranged between a first and a second axial element in such a way that a torque can be transmitted via said shaft from the first axial element to the second axial element or vice versa, thereby causing a relative displacement between the first axial element and the second axial element by a rolling movement of rolling bodies of the anti-friction bearing. The anti-friction bearing comprises at least one pair of bearing units with a first bearing unit and a second bearing unit, each bearing unit having a plurality of rolling bodies, the first bearing unit supporting the first axial element in a play-free manner or with pretension in the peripheral direction of the shaft against the second axial element, while the second bearing unit supports the first axial element against the second axial element in a play-free manner or with pretension in a second peripheral direction which is directed opposite to the first peripheral direction of the shaft. The rolling bodies have a cylindrical or cone-shaped outer surface and are oriented with their rotating axes in the radial direction of the two axial elements or are forming an acute angle thereto such that, when viewing in the peripheral direction of the shaft, they execute a rolling movement on a flat surface that extends over a predetermined diameter region. The bearing units are arranged at the axial end of the first axial element and are oriented towards the second axial element. In the region of the axial end of the second axial element, which is oiented towards the first axial element, a sliding element is arranged in the zone between the first and the second axial element in such a way that a supporting force which is directed in the radial direction of the shaft can be transmitted from the first axial element to the second axial element and vice versa via said sliding element, thereby allowing the relative displacement between the first axial element and the second axial element by a sliding movement while the sliding element is free of torque transmission between the first axial element and the second axial element.

Abstract

The invention relates to a torsional vibration damper with a flexible coupling (2), comprising at least one first coupling element (3) which can be connected to a driving element, at least one second coupling element (4) which can be connected to a power take-off in a rotationally fixed manner, said elements being at least indirectly coupled to each other via spring and/or damping coupling means (5). The damper also comprises a device (6) for detecting at least one variable that is at least indirectly characteristic of the mode of functioning and/or operation of the flexible coupling. The invention is characterized by the following features: the device (6) for detecting at least one variable that is at least indirectly characteristic of the mode of functioning is integrated into the flexible coupling (2); the device for detecting at least one variable that is at least indirectly characteristic of the mode of operation of the flexible coupling comprises means (15) for acquiring the operational characteristics and a permanently mounted interface (7), comprising means (8) for reading out the variables that are at least indirectly characteristic of the mode of operation of the flexible coupling (2).

Abstract

The invention relates to a hydrodynamic brake with a rotor comprising a rotor blade wheel and with a stator comprising a stator blade wheel, the rotor blade wheel and the stator blade wheel, together, forming a working space that can be filled with a working medium for transmitting driving power from the rotor to the stator. The rotor comprises a rotor shaft, which supports the rotor blade wheel and which is rotationally mounted by means of a bearing having at least two or exactly two antifriction bearings. The invention is characterized by the following features: the bearing of the rotor shaft comprises a first antifriction bearing that can absorb a predetermined first axial force and further comprises a second antifriction bearing, which is arranged in an axially lateral manner with regard to the first antifriction bearing and which can absorb a predetermined second axial force, the second axial force being greater than the first axial force, and the rotor blade wheel is arranged laterally opposite the stator blade wheel on the same axial side as the first antifriction bearing opposite the second antifriction bearing so that an axial force from the rotor blade wheel toward the stator blade wheel is absorbed by the second antifriction bearing.

Abstract

The invention relates to a life usage tracking system (1) for a flexible coupling (2), comprising at least one first coupling element (3) which can be connected to a driving element, and at least one second coupling element (4) which can be connected to a power take-off, said elements being at least indirectly coupled to each other via spring and/or damping coupling means (5). The spring and/or damping coupling means (5) comprise at least one elastomer component (7). The tracking system also comprises a device (7) for indicating the remaining operational life, said device being connected to or integrated into the flexible coupling. The invention is characterized in that the device comprises a physicochemical marker (9) for indicating the remaining operational life of the elastomer, said physicochemical marker being integrated into the elastomer component or being connected to the same. The physicochemical marker is subject to a visually perceptible change in properties that increases depending on the load cycles passed into the elastomer component and the visually perceptible property can be perceived irrespective of the load condition of the elastomer component.

Abstract

The invention relates to a drive unit for driving at least one wheel drive shaft, particularly a wheelset axle for use in vehicles, particularly railway vehicles, with a transmission unit comprising at least one output, the output of the transmission unit being formed by a hollow shaft coupled via an articulated coupling to the wheel drive shaft, particularly the wheelset axle. The articulated coupling comprises a first coupling part connected to the hollow shaft and comprises a second coupling part, which can be coupled to the wheel drive shaft, particularly the wheelset axle. Elastic bearing packs are placed between the first and second coupling parts. The invention is characterized by the following features: the first coupling part comprises an annular flange, which is placed on the outer periphery of the hollow shaft and, together with the hollow shaft (8), is provided as a single piece; the second coupling part comprises a hub part with arm-shaped elements, which extend in a radial direction and which can be detachably connected to the wheelset axle, and; the bearing packs are assigned to a coupling part.
