Abstract
(DE)
Die Erfindung betrifft ein Getriebe (10) welches ein Gehäuse (12) als erstes Bauteil und ein in dem Gehäuse (12) angeordnetes, separat von dem Gehäuse (12) ausgebildetes und wenigstens eine Verzahnung (18) aufweisendes Getriebeelement (16) als zweites Bauteil aufweist. Das Gehäuse (12) und das Getriebeelement (16) wirken über jeweilige, in einer Flanschebene (26) angeordnete Flanschflächen (22, 24) der Bauteile drehmomentübertragend zusammen. Es ist außerdem wenigstens ein einerseits durch das Gehäuse (12) und andererseits durch das Getriebeelement (16) begrenzter und zumindest teilweise in der Flanschebene (26) und neben den Flanschflächen (22, 24) angeordneter Dichtspalt (34) vorgesehen, in welchem wenigstens ein Dichtungselement (36) angeordnet ist. Mittels des Dichtungselements (36) sind die Bauteile gegeneinander abgedichtet.
(EN)
The invention relates to a transmission (10) which has a housing (12) as a first component and a transmission element (16) as a second component, which transmission element is arranged in the housing (12), is formed separately from the housing (12) and has at least one toothing (18). The housing (12) and the transmission element (16) interact in a torque-transmitting manner via respective flange surfaces (22, 24) of the components, which flange surfaces are arranged in a flange plane (26). In addition, at least one sealing gap (34) is provided, which is delimited on one side by the housing (12) and on the other side by the transmission element (16) and is arranged at least partially in the flange plane (26) and next to the flange surfaces (22, 24), in which at least one sealing gap at least one seal element (36) is arranged. The components are sealed against each other by means of the seal element (36).

L'invention concerne un engrenage (10), lequel comporte un boîtier (12) en tant que premier composant et un élément (16) d'engrenage disposé dans le boîtier (12), réalisé séparément du boîtier (12) et comportant au moins une denture (18) en tant que deuxième composant. Le boîtier (12) et l'élément (16) d'engrenage coopèrent avec transmission d'un couple de rotation par l'intermédiaire de surfaces de brides (22, 24) respectives, disposées dans un plan de bride (26), des composants. L'invention prévoit par ailleurs au moins une fente étanche (34) délimitée d'une part par le boîtier (12) et d'autre part par l'élément (16) d'engrenage et disposée au moins en partie dans le plan de bride (26) et à côté des surfaces (22, 24) de bride, dans laquelle est disposé au moins un élément d'étanchéité (36). Les composants sont étanchéifiés les uns par rapport aux autres au moyen de l'élément d'étanchéité (36).
