Title
(DE) ELEKTRISCHE MASCHINENANORDNUNG
(EN) ELECTRIC MACHINE ARRANGEMENT
(FR) AGENCEMENT DE MACHINE ÉLECTRIQUE
Abstract
(DE) Die Erfindung betrifft eine elektrische Maschinenanordnung (1 ), umfassend eine erste elektrische Maschine (21 ), eine zweite elektrische Maschine (22) mit jeweils einem Stator (31, 32) und mit jeweils einem Rotor (41, 42), umfassend ferner ein gemeinsames Gehäuse (7), in dem die beiden elektrischen Maschinen (21, 22) axial benachbart zueinander angeordnet sind, sowie umfassend eine in drehfestem Kontakt mit dem Rotor (41 ) der ersten elektrischen Maschine (21 ) stehende Abtriebswelle (101 ) und eine in drehfestem Kontakt mit dem Rotor (42) der zweiten elektrischen Maschine (22) stehende Abtriebswelle (102). Dabei ist der Rotor (41 ) der ersten elektrischen Maschine (21) auf seiner der zweiten elektrischen Maschine (22) abgekehrten Seite über ein erstes Lager (611) drehbar gelagert in oder an einem Stützteil (S) des Gehäuses (7) radial abgestützt angeordnet und ist der Rotor (42) der zweiten elektrischen Maschine (22) auf seiner der ersten elektrischen Maschine (21) abgekehrten Seite über ein zweites Lager (612) drehbar gelagert in oder an einem Stützteil (S) des Gehäuses (7) radial abgestützt angeordnet. Einer der beiden Rotoren (41, 42) ist auf seiner dem anderen Rotor (42, 41 ) zugekehrten Seite über ein drittes Lager (613) radial gegen den anderen Rotor (42, 41 ) abgestützt. Erfindungsgemäß ist der Rotor (41 ) der ersten elektrischen Maschine (21 ) oder der Rotor (42) der zweiten elektrischen Maschine (22) über ein viertes Lager (614) radial abgestützt.
(EN) The invention relates to an electric machine arrangement (1), comprising a first electric machine (21) and a second electric machine (22), each having a stator (31, 32) and each having a rotor (41, 42), further comprising a common housing (7), in which the two electric machines (21, 22) are arranged axially adjacent to one another, and also comprising an output shaft (101) that is in rotationally fixed contact with the rotor (41) of the first electric machine (21) and an output shaft (102) that is in rotationally fixed contact with the rotor (42) of the second electric machine (22). The rotor (41) of the first electric machine (21) here, on its side that is averted from the second electric machine (22), is arranged with radial support in or on a supporting part (S) of the housing (7) in a manner rotatably mounted by means of a first bearing (611) and the rotor (42) of the second electrical machine (22), on its side that is averted from the first electric machine (21), is arranged with radial support in or on a supporting part (S) of the housing (7) in a manner rotatably mounted by means of a second bearing (612). One of the two rotors (41, 42), on its side that faces the other rotor (42, 41), is supported radially against the other rotor (42, 41) by means of a third bearing (613). According to the invention, the rotor (41) of the first electric machine (21) or the rotor (42) of the second electric machine (22) is radially supported by means of a fourth bearing (614).
(FR) L'invention concerne un agencement de machine électrique (1) comprenant une première machine électrique (21) et une seconde machine électrique (22) comportant chacune un stator (31, 32) et chacune un rotor (41, 42), comprenant en outre un boîtier commun (7), dans lequel les deux machines électriques (21, 22) sont disposées axialement l'une à côté de l'autre, et comprenant également un arbre de sortie (101) qui est en contact fixe en rotation avec le rotor (41) de la première machine électrique (21) et un arbre de sortie (102) qui est en contact fixe en rotation avec le rotor (42) de la seconde machine électrique (22). Le rotor (41) de la première machine électrique (21), sur son côté opposé à la seconde machine électrique (22), est agencé avec un support radial dans ou sur une partie de support (S) du boîtier (7) de manière à pouvoir tourner au moyen d'un premier palier (611), et le rotor (42) de la seconde machine électrique (22), sur son côté opposé à la première machine électrique (21), est agencé avec un support radial dans ou sur une partie de support (S) du boîtier (7) de manière à pouvoir tourner au moyen d'un deuxième palier (612). L'un des deux rotors (41, 42), sur son côté tourné vers l'autre rotor (42, 41), est supporté radialement contre l'autre rotor (42, 41) au moyen d'un troisième palier (613). Selon l'invention, le rotor (41) de la première machine électrique (21) ou le rotor (42) de la seconde machine électrique (22) est supporté radialement au moyen d'un quatrième palier (614).
