Description
Lagerung der Schnecke eines Schneckengetriebes Die Erfindung bezieht sich auf eine Lagerung der Schnecke eines Schneckengetriebes in inem Gehäuse, insbesondere auf die Lagerung der Schnecke eines Schneckengetriebes zua Schwenken eines Schraubenentriebes eines Amphibienfahrzeuges um 360°. Storage of the worm of a worm gear The invention relates on a storage of the worm of a worm gear in a housing, in particular on the storage of the worm of a worm gear to a pivoting of a screw drive an amphibious vehicle by 360 °.
Bei Amphibienfahrzeugen wird der Schraubenantrieb zur Vorwärtzbewegung des Fahrzeuges im Wasser zur Erzielung grober Wendige keit so ausgebildet, daß mit einer Schnecke ein Schneckenrad angetrieben wird, das den Schraubenantrieb in belde@ Drehrichtungen us 360° dreht. Um schädliche Schwingungen zu vermeiden, ist es erforderlich1 den Eingriff zwischen Schnecke und Schnecke rad spielfrei zu halten bor erfindung liegt die Aufhabe zugrunde, die Lagerung der Schnecke mit geringem Aufwand so auszubilden, daß die gewünschte Spielfreiheit im Eingriff erreicht wird. Erfindungagemäß wird die gestellte Aufgabe dadurch geldat, daß die Lager der Schnecke (Gleitlager, Wälzlager) ihrerseite elastisch im Gehäuse gelagert sind und der Abstand zwischen der Mittellängsachse durch die Schnecke und der Mittellänchse durch das Schneckenrad des Schneckengetriebes kleiner ausgebildet ist als es da. hereshnungsnusweist, Durch die Maßnahme wird eine bleibende Vorapannung in der Lagerung der Schnecke erzielt, durch die ein spielfreier Einyriff der Schnecke in das Schneckenrad sichergestellt ist.In amphibious vehicles, the screw drive becomes the forward movement of the vehicle in the water to achieve rough maneuverability designed so that with a worm a worm wheel is driven, which the screw drive in belde @ Directions of rotation us 360 °. In order to avoid harmful vibrations, it is necessary1 To keep the engagement between worm and worm wheel backlash-free bor invention the aim is to design the storage of the screw with little effort in such a way that that the desired freedom from play is achieved in the engagement. According to the invention the task set by the fact that the bearings of the worm (plain bearings, roller bearings) their side are elastically mounted in the housing and the distance between the central longitudinal axis through the worm and the central lance through the worm wheel of the worm gear is made smaller than it is there. hereshnungsnus shows, by the measure will a permanent pre-tensioning achieved in the storage of the screw, through which a backlash-free Einyriff the worm in the worm wheel is ensured.
Schädliche Schwingungen können nicht auftreten.Harmful vibrations cannot occur.
In einfacher Weise kann die elastische Lagerung durch Gummi-oder Kunststoffbüchsen vorgenommen sein. Vorteilhaft können diese Gummi- oder Kunststof£büchsen bei gleichbleibender Wandstärke konisch ausgebildet sein und können Jeweils mit dem gröberen Durchmesser einander zugekehrt angeordnet sein. Dadurch wird die Schnecke gegen Verschiebungen in deren Längsrichtung sicher abgeetützt.In a simple manner, the elastic mounting can be achieved by means of rubber or plastic bushings be made. These rubber or plastic bushings can be advantageous with the same Wall thickness can be conical and can each have the coarser diameter be arranged facing each other. This will prevent the worm from shifting safely supported in the longitudinal direction.
In der Zeichnung ist,der Gegenstand der Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing is the subject of the invention in one embodiment shown.
Bei einem Schraubenantrieb für ein Amphibienfahrzeug kann die Antriebsschraube kopeller) mit ihrem antriebsgehäuse um 3600 gedreht werden, um auf diese Weise eine vorzüglicbe Manövrierfähigkeit für das Fahrzeug zu erlangen. Das Drehen des Antriebsgehäuses gegenüber einem festen Gehäuseteil 1 wird von einem aus einer Schnecke 2 und aus einem Schneckenrad 3 bestehenden Schneckengetriebe vorgenommen. Das Schneckenrad 3 ist über einer lotrechten Triebwelle angeordnet, die über ein Kegelrad von dem Kegelrad 4 angetrieben wird. Die lotrechte Triebwelle ist mit einer Bohrung-versehen, in der eine mit dem Schneckenrad 3 verbundene Welle 3 angeordnet ist, die eins Drehbewegung des Schnecken rades 3 auf das Antriebegehäuse überträgt. Die Schnecke 2 ist an der Antriebsseite mit einem Gleitlager 6 und an der anderen Seite mit Wäl-zlagern 7 im Gehäuseteil 1 gelagert.In the case of a screw drive for an amphibious vehicle, the drive screw Kopeller) with its drive housing can be rotated by 3600 to create a To obtain excellent maneuverability for the vehicle. The turning of the drive housing compared to a fixed housing part 1 is from a screw 2 and from one made a worm gear 3 existing worm gear. The worm wheel 3 is arranged over a vertical drive shaft, which is via a bevel gear of the Bevel gear 4 is driven. The vertical drive shaft is provided with a hole, in which a shaft 3 connected to the worm wheel 3 is arranged, the one rotational movement of the worm wheel 3 transfers to the drive housing. The screw 2 is at the Drive side with a plain bearing 6 and on the other side with roller bearings 7 stored in the housing part 1.
Um zu erreichen, daß der Eingriff zwischen der Schnecke 2 und dem Schneckenrad 3 stets spielfrei erfolgt, so daß schädliche Schwingungen vermieden werden k6nnen1wordad sowohl das Gleitlager 6 als auch die Wälzlager 7 ihrerseits in elastischen Gummibllchsen 8 gelagert, wobei der Abstand a zwischen der Nittellängsachse 9 durch die Schnecke 2 und der Mittellängsachas 10 durch das Schneckenrad 3 kleiner ausgebildet ist als es das theoretische Berachnungsmaß ausweist. Dadurch wird von den Gummibüchsen 9 ständig ein Druck ausgeübt, der die Schnecke 2 gegen das Scllnekkenrad 3 drUckt.To achieve that the engagement between the screw 2 and the Worm gear 3 is always backlash-free, so that harmful vibrations are avoided Both the plain bearing 6 and the roller bearings 7 for their part can become mounted in elastic rubber bushes 8, the distance a between the central longitudinal axis 9 by the worm 2 and the central longitudinal axis 10 by the worm wheel 3 smaller is trained as it shows the theoretical allowance. This will result from the rubber bushes 9 constant pressure exerted by the snail 2 presses against the worm gear 3.
Die Gummibtichsen 8 sind bei gleichbleibender Wandstärke konisch ausgebildet und derart angeordnet, daX die Enden mit den gröUeren Durchmessern einander zugekehrt sind. Infolge der konischen Ausbildung der Gummibüchsen sind auch die gehäusefesten Lagerteile ii und zwischen den Lagern 6, 7 und den Gummibüchsen ö liegende Lagerteile 12 mit konischen Lagerflächen versehen.The rubber bushings 8 are conical in shape while the wall thickness remains the same and arranged in such a way that the ends with the larger diameters face one another are. Due to the conical design of the rubber bushings, they are also fixed to the housing Bearing parts ii and between the bearings 6, 7 and the rubber bushings ö lying bearing parts 12 provided with conical bearing surfaces.
