Abstract: Bei herkömmlichen Bürstenanordnungen für elektrische Maschinen mit auswechselbaren Bürsten beeinträchtigt die Vielzahl zu demontierenden und wieder anzubauenden, zu einer Steckeinheit zusammengefaßten Bauteile die Stabilität der gesamten Bürstenanordnung. Die Steckeinheiten sind darüber hinaus unbequem in der Handhabung. Es wird eine Bürsteneinheit vorgeschlagen, bei welcher lediglich das zu kontrollierende und/oder auszuwechselnde Bauteil, nämlich die Bürste (14) sowie wenig zusätzliche Bauteile von der Bürstenbrücke getrennt werden müssen, während die Bauteile, welche die Steifigkeit der Bürstenanordnung bestimmen, in ihrer starren Verbindung mit der Maschine belassen werden. Dies erfolgt dadurch, daß die Bürstentaschen (6) integraler Bestandteil der feststehenden Bürstenbrücke sind, die Bürsten (14) auf Bürstentragelementen (8) in radialer Richtung beweglich angeordnet und gleichzeitig Träger der Federn (9) für die Anpressung der Bursten (14) an den rotierenden Kontaktteil (1) sind.

Abstract: A signal communicator for transmitting an electrical signal from one member 10 rotating relative to another member 16 is in the configuration of a journal bearing and is characterized by at least one conically shaped annular graphite ring 40 supported by inner and outer electrically conductive races 42, 44. While one race is insulatively mounted on the rotating member and electrically connected to a condition sensor, the other race is insulatively mounted on the relatively stationary member and electrically connected to a signal detector, and the graphite ring 40 is an electrical conductor interconnecting the sensor and detector via the two races 42, 44. Alternatively, two opposing and contacting graphite rings 120, 130 are mounted in nonconducting carriers 122, 132, one of the carriers keyed for rotation with the sensor while the other is mounted on the relatively stationary member. Electrical connections are made directly from the sensor to one of the graphite rings and from the detector to the other of the graphite rings and the rings therefore function as the electrical interconnection between the rotating sensor and the relatively stationary detector.
