Description
Die Erfindung betrifft ein Getriebe, umfassend ein Getriebegehäuse, in dem zu mindest zwei relativ verdrehbare Zahnräder angeordnet sind, die miteinander in Eingriff stehen.The invention relates to a transmission, comprising a transmission housing, in which at least two relatively rotatable gear wheels are arranged, who are engaged with each other.
Ein solches Getriebe ist bekannt. Die durch das Ineinandergreifen der Zahnräder verursachten Schwingungen werden dabei im wesentlichen unvermindert auf das Getriebegehäuse übertragen und von diesem abgestrahlt. In akustischer Hinsicht ist das wenig befriedigend.Such a transmission is known. The through the meshing of the gears Vibrations caused are essentially undiminished the transmission housing transmitted and radiated from this. In acoustic That is not very satisfactory.
Der Erfindung liegt die Aufgabe zugrunde, ein solches Getriebe derart weiterzu entwickeln, daß sich eine verminderte Schallabstrahlung in die Umgebung er gibt.The invention has for its object to continue such a transmission develop that he a reduced sound radiation in the environment gives.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen von Anspruch 1 ge löst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug.This object is achieved according to the invention with the features of claim 1 solves. The subclaims refer to advantageous refinements.
Bei dem erfindungsgemäßen Getriebe ist es vorgesehen, daß die Zahnräder an zumindest einem Ende in einer gemeinsamen Lagerbrille gelagert sind und durch die Lagerbrille zur Reduzierung einer Schalleinleitung in das Getriebegehäuse durch einen elastischen Federring aus polymerem Werkstoff von dem Getriebe gehäuse getrennt ist. Die durch das Ineinandergreifen der Zahnräder verursach ten Schallschwingungen werden bei der erfindungsgemäßen Bauform wesentlich gemindert auf das Getriebegehäuse übertragen und von diesem in deutlich verringertem Maße an die Umgebung abgestrahlt.In the transmission according to the invention it is provided that the gears on at least one end are stored in common bearing glasses and through the bearing glasses to reduce sound transmission into the gearbox by an elastic spring ring made of polymer material from the gearbox housing is separated. That caused by the meshing of the gears th sound vibrations are essential in the design according to the invention reduced transferred to the gearbox and from this clearly radiated to a lesser extent to the environment.
Unabhängig hiervon ist die gegenseitige Zuordnung der miteinander in Eingriff stehenden Zahnräder in präziser Weise festgelegt. Hinsichtlich der mechani schen Gebrauchseigenschaften und insbesondere hinsichtlich der Dauerhaltbar keit unterscheidet sich das erfindungsgemäße Getriebe nicht von den bisher be kannten Ausführungen.Regardless of this, the mutual assignment of the one another is in engagement stationary gears set in a precise manner. Regarding the mechani use properties and especially with regard to durability speed, the transmission according to the invention does not differ from the previously be knew versions.
Die Zahnräder können mittels einer einstückig angeformten Welle in der Lager brille aufgenommen sein oder mittels einer Welle, die unabhängig von den Zahn rädern erzeugt und nachträglich in dieser eingefügt ist. Bei beiden Baumformen resultiert während der bestimmungsgemäßen Verwendung eine Übertragung von Schallschwingungen der Zahnräder auf die Lagerung. Ein darüber hinausgehende Weiterleitung der Schallschwingungen ist durch die erfindungsgemäßen Maßnahmen wesentlich reduziert. Die erfindungsgemäßen Maßnahmen führen daher bei beiden Bauformen zum vollen Erfolg.The gears can be formed in the bearing by means of an integrally molded shaft glasses or by means of a shaft that is independent of the tooth wheels created and subsequently inserted into this. With both tree shapes results in a transfer of Sound vibrations of the gears on the bearing. A further one Forwarding of the sound vibrations is by the invention Measures significantly reduced. The measures according to the invention lead therefore a complete success with both designs.
Da das Getriebegehäuse bei dem erfindungsgemäßen Getriebe nicht mehr in dem hohen Maße körperschallerregt schwingt und der akustischen Auslegung weniger Aufmerksamkeit gewidmet werden muß, können Gestaltfestigkeiten und Gewicht des Gehäuses noch weiter optimiert werden.Since the transmission housing in the transmission according to the invention is no longer in the high level of structure-borne noise and the acoustic design Less attention needs to be paid to structural strengths and weight of the housing can be further optimized.
Eine wesentliche Verbesserung der akustischen Wirksamkeit läßt sich erzielen, wenn die Zahnräder an beiden Enden jeweils in einer gemeinsamen Lagerbrille gelagert und durch elastische Federringe aus polymerem Werkstoff akustisch von dem Getriebegehäuse isoliert sind. Schallschwingungen können bei einer solchen Bauform das Getriebegehäuse auch auf "Umwegen" nicht erreichen. Zweckmäßig ist das Getriebegehäuse an jeder Lagerstelle der Zahnräder durch einen elastischen Federring aus polymerem Werkstoff akustisch gegenüber den Zahnrädern isoliert.A significant improvement in acoustic effectiveness can be achieved if the gears at both ends in common bearing glasses stored and acoustically by elastic spring washers made of polymer material are isolated from the gear housing. Acoustic vibrations can occur at a such a design, the gearbox can not reach "detours". The gear housing is expedient at each bearing point of the gear wheels an elastic spring ring made of polymeric material acoustically opposite the Gears isolated.
Unter montagetechnischen Gesichtspunkten hat es sich als Vereinfachung be währt, wenn der Federring in einem Spalt zwischen der Lagerbrille und einem Halteteil angeordnet ist, das mit dem Getriebegehäuse verschraubbar ist. In be zug auf eventuell erforderliche Demontagen ergibt sich bei solchen Bauformen keine Veränderung in bezug auf die bisher gebräuchlichen Ausführungen. From an assembly point of view, it has proven to be a simplification lasts if the spring ring is in a gap between the bearing glasses and a Holding part is arranged, which can be screwed to the gear housing. In be Such types of construction result in the need for disassembly no change in relation to the previously used designs.
Als vorteilhaft hat es sich erwiesen, wenn der Federring aus elastomerem Werkstoff besteht und durch unmittelbares Anvulkanisieren mit der Lagerbrille und dem Halteteil verbunden ist. Einerseits wird durch das unmittelbare Anvulkanisieren eine unlösbare, flüssigkeitsdicht Verbindung zwischen der Lagerbrille und dem Halteteil erreicht. Andererseits sind Federringe aus elastomerem Werkstoff hervorragend geeignet, über lange Zeiträume eine gute schwingungstechnische Isolierung zwischen der Lagerbrille und dem Getriebegehäuse zu gewährleisten.It has proven to be advantageous if the spring ring is made of elastomeric Material exists and by direct vulcanization with the bearing glasses and is connected to the holding part. On the one hand, the immediate Vulcanizing an inseparable, liquid-tight connection between the Camp glasses and the holding part reached. On the other hand, spring washers are off excellent material, a good one over long periods of time vibration isolation between the bearing glasses and the To ensure gearbox.
Die Erfindung wird nachfolgend anhand der beigefügten Zeichnungen weiter verdeutlicht.The invention will now be further elucidated with reference to the accompanying drawings clarifies.
Es zeigen:Show it:

Fig. 2 das Getriebe gemäß Fig. 1 in einer teilweise längsgeschnittenen Darstel lung. Fig. 2, the transmission of FIG. 1 in a partially longitudinally presen- tation.
Das in Fig. 1 und 2 gezeigte Getriebe umfaßt ein Getriebegehäuse 1, in dem zumindest zwei relativ verdrehbare Zahnräder 4, 5 angeordnet sind, die mitein ander in Eingriff stehen. Die Zahnräder 4, 5 sind an bei den Enden in gemeinsa men Lagerbrillen 6 gelagert, von denen die vordere sichtbar ist. Diese ist zur Reduzierung einer Schalleinleitung in das Getriebegehäuse 1 durch einen elasti schen Federring 8 aus Weichgummi von dem Getriebegehäuse getrennt. Durch den gegenseitigen Zahneingriff der Zahnräder verursachte Schallschwingungen können dadurch nicht mehr auf das Getriebegehäuse übertragen und von diesem in die Umgebung abgestrahlt werden.The transmission shown in Fig. 1 and 2 comprises a gear housing 1 , in which at least two relatively rotatable gears 4 , 5 are arranged, which are in engagement with each other. The gears 4 , 5 are supported at the ends in common men bearing glasses 6 , of which the front is visible. This is separated from the gear housing by an elastic spring washer 8 made of soft rubber to reduce the introduction of sound into the gear housing 1 . Sound vibrations caused by the mutual meshing of the gears can therefore no longer be transmitted to the transmission housing and radiated from the latter into the surroundings.
