Description
Vorliegende Erfindung bezieht sich auf ■ Vorgelege, die mit einem geschlossenen Elektromotor zusammengebaut sind. Bei geschlossenen Motoren erfolgt die Kühlung der Wicklungen gewöhnlich in bekannter Weise durch eine im Innern des Gehäuses stattfindende Luftumwälzung, wobei die Wärme durch die Gehäusewand nach außen abgeführt wird. Beim Zusammenbau mit einem Vorgelege zeigt es sich jedoch, daß das Vorgelege durch den an seinem Gehäuse entlangstreichenden warmen Luftstrom des Motors zusätzlich erwärmt wird. Dies ist von besonderem Nachteil, weil die Reibungsarbeit in dem Vorgelege ebenfalls eine gewisse Wärmemenge erzeugt, so daß unzulässig hohe Temperaturen entstehen. Ferner wird durch einen auf der Rotorwelle neben dem Vorgelege angebrachten Zentrifugallüfter ein Unterdruck erzeugt, der bei nicht ganz sorgfältiger Abdichtung Schmiermittel aus dem Vorgelege ansaugt.The present invention relates to ■ countershafts with a closed electric motor are assembled. In the case of closed motors, the windings are cooled usually in a known manner by a circulation of air inside the housing, the heat through the Housing wall is discharged to the outside. When assembling with an intermediate gear, however, it turns out that the intermediate gear through the warm air flow of the motor brushing along its housing is additionally heated will. This is of particular disadvantage because of the frictional work in the back gear also generates a certain amount of heat, so that inadmissibly high temperatures arise. Furthermore, one on the A centrifugal fan attached to the rotor shaft next to the countershaft generates a vacuum, which sucks in lubricant from the transmission if the sealing is not very careful.
Diese Nachteile werden erfindungsgemäßThese disadvantages become according to the invention
dadurch vermieden, daß zwischen dem Motor und der demselben zugekehrten Wand des Vorgelegehäuses eine besondere Trennfläche eingeschaltet ist, die den erwärmten Maschinenkühlstrom von dem Vorgelege abhält. Diese Trennfläche kann entweder am Gehäuse des Motors oder auf der Rotorwelle befestigt sein.avoided that between the engine and the wall facing the same Countershaft housing a special separation surface is switched on, which the heated machine cooling flow from the transmission. This interface can either be attached to the housing of the motor or to the rotor shaft be.
Die erste Ausführungsform hat den Vorteil, daß die von dem Vorgelege gebildete Luftschicht von dem Kühlluftstrom des Motors vollkommen getrennt und dadurch ohne weiteres mit der Außenluft in Verbindung gebracht werden kann. Hierbei wird aber die Saugwirkung des Lüfters auf das Vorgelege nicht vollkommen ausgeschaltet. Dies kann durch die zweite Ausführungsform erreicht werden, bei der der Lüfter nur von der Motorseite her ansaugen kann. Dann verbleibt die Luftschicht in der Nähe des Vorgeleges in vollständiger Ruhe, weil sie durch den abgelenkten heißen Luftstrom nicht beeinflußt wird, und es wird keine Wärme auf das Vorgelege übertragen.The first embodiment has the advantage that that formed by the lay-up The air layer is completely separated from the cooling air flow of the motor and thus easily in contact with the outside air can be brought. In this case, however, the suction effect of the fan on the lay-up is not completely switched off. This can be achieved by the second embodiment, in which the fan is only from the engine side can suck in. Then the air layer remains in the vicinity of the lay-up in complete rest because it is not affected by the deflected hot air flow and no heat is transferred to the lay-up.
Die Kühlung des Motors wird dadurch nicht ungünstig beeinflußt, weil die umgewälzte Luft durch die einseitige Führung die Wicklungen schärfer durchstreicht.The cooling of the motor is not adversely affected because the circulated Air passes through the windings more sharply through the one-sided guide.
