Abstract
Description
Als Getriebemotoren sind Kombinationen eines Elektromotors mit einem Getriebe bekannt, bei denen der Motor am Getriebegehäuse angeflanscht ist (EP-A-69 215). Wenn der Wellenzapfen des Motors die Stirnradverzahnung der ersten Getriebestufe trägt, ergibt sich eine sehr wirtschaftliche Lösung, weil die separate Lagerung der eintreibenden Welle und eine Verbindung zwischen dieser Welle und der Motorwelle entfällt. Da der Motor jedoch eine Sonderanfertigung mit Ritzelwelle, verstärkter Lagerung und Ölabdichtung ist, ist seine Beschaffung nicht so problemlos wie die eines Normmotors. In manchen Fällen zieht man aus diesem Grund die Verwendung eines Normmotors vor. Das ist ein Elektromotor, dessen Welle in einem Wellenstumpf endet, der mit einer Kupplung oder dergleichen verbindbar ist. Für seine Verbindung mit dem Getriebe ist ein Adapter erforderlich. Der Adapter enthält eine eigene Lagerung der eintreibenden Welle, die die Ritzelverzahnung der ersten Getriebestufe trägt, und ist über eine Wellenkupplung mit dem Wellenstumpf des Motors verbunden. Dabei ist es be kannt (US-A-4111069), in dem Adapter selbst lediglich ein Lager für die Adapterwelle vorzusehen, während das zweite Lager jenseits ihres Ritzels im Getriebegehäuse angeordnet ist.When Geared motors are combinations of an electric motor with a Gear known, in which the engine is flanged to the gear housing (EP-A-69 215). If the shaft journal of the engine is the spur gear teeth wearing the first gear, This results in a very economical solution, because the separate storage the driving shaft and a connection between this shaft and the motor shaft is omitted. However, as the engine is a custom-made with pinion shaft, reinforced bearings and oil seal is, his procurement is not as problem-free as that of a standard engine. In some cases For this reason, we prefer to use a standard motor. This is an electric motor whose shaft ends in a stub shaft, which is connectable with a clutch or the like. For his connection the gearbox requires an adapter. The adapter contains a own storage of the driving shaft, which is the pinion of the first gear stage, and is over a shaft coupling connected to the stub shaft of the engine. there it is be known (US-A-4111069), in the adapter itself only one Warehouse for to provide the adapter shaft while the second bearing is located beyond its pinion in the transmission housing.
Die Erfindung greift diesen Gedanken für eine spezielle Getriebebauform auf und erreicht dadurch eine gedrängtere Bauweise. Sie besteht darin, dass bei einem Getriebe mit koaxial zu der Adapterwelle angeordneter Abtriebswelle das getriebeseitige Lager der Adapterwelle im antriebesseitigen Ende der Abtriebswelle angeordnet ist.The Invention grasps this idea for a special gearbox design and achieved thereby a more crowded construction. she consists in that in a transmission with coaxial with the adapter shaft arranged Output shaft, the transmission-side bearing of the adapter shaft in the drive-side End of the output shaft is arranged.
Diese Anordnung ist besonders dann von Vorteil, wenn es sich um ein zweistufiges Getriebe handelt, bei welchem der Drehsinn der Adapterwelle und der Abtriebswelle gleich ist. Das Adapterwellenlager ist dabei nämlich nur der Differenzdrehzahl zwischen diesen beiden Wellen ausgesetzt.These Arrangement is particularly advantageous when it comes to a two-stage Transmission is, in which the sense of rotation of the adapter shaft and the output shaft is the same. The adapter shaft bearing is namely only exposed to the differential speed between these two waves.
Zwar ist eine ähnliche Konstruktion von einem Drehmomentverstärker für Bohrwerke bekannt (US-A-3217556); jedoch liegt dieser eine Besonderheit zugrunde, die die Übertragung auf eine Adapterwellenlagerung nicht naheliegend erscheinen lässt. Der bekannte Drehmomentverstärker weist eine Eintriebsspindel auf, die statt eines Bohrers mit der Bohrspindel des Bohrwerks zu verbinden ist, und hat eine dazu koaxiale Abtriebsspindel, in die ein Bohrer eingesetzt werden kann. Dank des durch ein zweistufiges Getriebe erhöhten Drehmoments der Abtriebsspindel können Bohrer großen Durchmessers verwendet werden, die oberhalb der dem Bohrwerk vorgegebenen Durchmessergrenze liegen. Dabei muss der Bohrdruck von der Bohrspindel des Bohrwerks über den Drehmomentverstärker auf den Bohrer übertragen werden und also auch von der Eintriebsspindel auf die Abtriebsspindel des Drehmomentverstärkers. Damit diese Kraftübertragung unmittelbar zu den beiden Spindeln unter Umgehung des Getriebegehäuses stattfinden kann, ist zwischen ihnen ein Drucklager angeordnet, das auch gleichzeitig zur zweiten Radiallagerung der Eintriebsspindel verwendet wird. Da die bekannte Konstruktion speziell unter der Voraussetzung steht, dass Axialkräfte von der Eintriebsspindel auf die Abtriebsspindel übertragen werden müssen, was bei einem Motoradapter nicht der Fall ist, und da der bekannte Drehmomentverstärker auch technisch obsolet zu sein scheint, konnte die Erfindung dadurch nicht nahegelegt werden.Though is a similar one Construction of a torque amplifier for boring mills known (US-A-3217556); however, this is a particularity underlying the transmission on an adapter shaft storage does not seem obvious. Of the known torque amplifier has a drive spindle, which instead of a drill with the drill spindle of the boring mill, and has a coaxial output spindle, in which a drill can be used. Thanks to a two-stage Gearbox increased Torque of the output spindle can drills of large diameter be used, which is above the diameter limit specified by the boring mill lie. The drilling pressure from the boring spindle of the boring mill must exceed the torque multipliers transferred to the drill and thus also from the input spindle to the output spindle of the torque amplifier. So this power transmission take place directly to the two spindles, bypassing the gear housing can, is arranged between them a thrust bearing, which is also the second Radial bearing of the input spindle is used. As the well-known Construction is specifically provided that axial forces of the input spindle must be transferred to the output spindle, which with a motor adapter is not the case, and there the known torque amplifier also technically obsolete, the invention could thereby not be suggested.
