However, the volume of the entire structure also increases accordingly.
[0005] This ultimately leads to more material outlay and material costs due to the larger dimensioning of the individual components and, moreover, the external dimensions of the generator are likewise unduly increased.

Embodiment Construction

[0029] figure 1 The electromechanical machine 1 , which is arranged in a housing 10 , is shown in schematic longitudinal section. In the housing 10 there is a laminated stator 2 which, during operation, guides the crankshaft 7 in rotation about an axis 27 via an air gap 26 by electromagnetic interaction with the rotor 3 . The rotor 3 , likewise embodied in laminated layers, is connected in a rotationally fixed manner to the crankshaft 7 . Housing 10 is supported on crankshaft 7 via bearing cage 9 and bearing 8 . The winding system 4 of the stator 2 has winding heads on the end faces of the stator 2 . Cooling channels extending substantially in the axial direction are provided in the stator 2 and / or the rotor 3 .

[0030] Likewise, the rotor 3 has on its end faces the winding ends of its winding system 5 , which is electrically conductively connected to the slip ring unit 6 via corresponding wires / conductors 29 . The winding system 5 of the rotor 3 is energized via the slip...

Abstract

A contact-making rotary transmission includes a brush forming an electrically conductive sliding contact element and a contact path of electrically conductive material for contact with the brush. The brush is guided and / or held by an arrangement which includes a plurality of carrier segments arranged axially behind one another. Each carrier segment has attached thereto a brush receptacle such as to define a first gap between the carrier segment and the brush receptacle. The brush receptacle includes a stationary receiving shaft which is formed by walls and configured to receive the brush, and a guide element which is provided on a wall of the receiving shaft so as to define a second gap between the brush and the wall. At least one of the walls includes an opening in communication with the first and second gaps to allow a flow of cooling air for cooling the brush.

Description

technical field [0001] The invention relates to an arrangement for guiding and / or holding an electrically conductive sliding contact element, a contact-type rotary transmission with such an arrangement, and an electromechanical machine with a contact-type rotary transmission. Background technique [0002] In electromechanical machines, in particular generators or drive motors, the rotor of the electromechanical machine can be fed or fed with electricity via a slip ring unit. In the case of larger electromechanical machines, such as generators of wind power plants, the generators and their components are now being constructed more and more compactly by optimizing the cost and construction space of wind power plants. This leads to the fact that the slip ring unit, ie the individual components of the slip ring unit, are subjected to higher and higher currents while the overall dimensions remain constant. For this reason, the temperature rises considerably at those locations, e...
