KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Diese Vorrichtung bezweckt, langen Schraubenspindeln, Wellen u. dergl. eine sichere Führung und Lagerung zu geben und Durchbiegungen durch das Eigengewicht oder Nebenkrä'fte, welche bei der Spindelwirkung auftreten und. sie aus ihrer Richtung zu bringen suchen, zu verhüten. ■ : The purpose of this device is to provide long screw spindles, shafts and the like with secure guidance and storage, and deflections due to their own weight or secondary forces that occur during the action of the spindle and. trying to get them out of their direction, to prevent them. ■ :
Die Vorrichtung ist in der Zeichnung beispielsweise in Anwendung auf eine Schraubenspindel dargestellt, und zeigtIn the drawing, the device is used, for example, on a screw spindle shown, and shows

Fig. 2 einen Schnitt durch ein Lager,2 shows a section through a bearing,
Fig. 3 einen Schnitt durch die Gewindemutter.3 shows a section through the threaded nut.
Die Schraubenspindel A, welche irgend einer beliebigen Maschine oder einem Apparat angehört, ist an ihren beiden Enden in zweckentsprechender Weise gelagert und in bekannter Weise an einem Ende mit der Antriebvorrichtung1 versehen. Auf dem Gewindeschafte ist die Gewindemutter B aufgesetzt, welche zu irgend einem zu betätigenden Support, Hebewerk u. s. w. gehört. Die Spindel selbst ist von den Lagern C1 C2 Cs C4 umschlossen und wird von diesen geführt. Die Anzahl dieser Lager richtet sich nach der Länge der Spindel, mufs aber stets eine gerade sein, da vor und hinter der Gewindemutter B eine gleiche Anzahl der Lager angeordnet wird.The screw spindle A, which belongs to any machine or apparatus, is appropriately supported at both ends and provided with the drive device 1 at one end in a known manner. The threaded nut B , which belongs to any support, lifting mechanism, etc. to be operated, is placed on the threaded shaft. The spindle itself is enclosed by the bearings C 1 C 2 C s C 4 and is guided by them. The number of these bearings depends on the length of the spindle, but must always be straight, since the same number of bearings is arranged in front of and behind the threaded nut B.
Die Lager sowohl als die Gewindemutter gleiten in Führungen!) und sind die Lagerkörper zur Erzielung einer langen Führung mit Lappen α α versehen, welche einander abgewendet angeordnet sind, so dafs zwei Lager dicht an einander stofsen können. Hierdurch gewinnen die Lager eine sichere Führung und werden in ihrer richtigen Lage zur Spindel gehalten, so dafs dieselbe sicher geführt und gegen seitliches Ausbiegen geschützt wird.The bearings as well as the threaded nut slide in guides!) And the bearing bodies are provided with tabs α α to achieve a long guide, which are arranged facing away from each other so that two bearings can butt close together. As a result, the bearings gain reliable guidance and are held in their correct position relative to the spindle, so that the same is safely guided and protected against lateral bending.
Die Lager selbst sind durch starre Verbindungen c cl je zwei zu einem Paare vereinigt derart, dafs von diesen je ein Lager vor und hinter der Mutter B steht und dafs die Lagerpaare einander überspringen. So bilden z. B. die Lager C1 und C4, ferner C2 und C3 solche Lagerpaare.The bearings themselves are combined into a pair by rigid connections cc l in such a way that one of these stands in front of and one behind the nut B and that the pairs of bearings jump over one another. So form z. B. the bearings C 1 and C 4 , also C 2 and C 3 such pairs of bearings.
Die Stellung dieser Lagerpaare zu einander wird durch die Bewegung der Gewindemutter B bedingt. In der Zeichnung ist die äufserste Stellung der Mutter B an einem Ende der Spindel angegeben, in welcher die Lager C3 C4 zusammengerückt sind, während die Lager C1 C2 die Unterstützung der Spindel besorgen.The position of these pairs of bearings in relation to one another is determined by the movement of the threaded nut B. In the drawing, the outermost position of the nut B is indicated at one end of the spindle, in which the bearings C 3 C 4 are moved together, while the bearings C 1 C 2 get the support of the spindle.
Die Wirkungsweise dieser ■ Vorrichtung ist nun folgende: Beim Antrieb der Spindel A in irgend einem Sinne geht die Gewindemutter' B in der betreffenden Richtung vorwärts, während die Lager C3 C4 ihre Stellung behalten. Hierbei stöfst die Mutter B an das Lager C2 an und nimmt dieses mit, wobei das mit C2 verbundene Lager C3 folgt. Je weiter die Mutter B vorgeht, um so mehr nähert sie sich dem Lager C\ bis sie an dieses anstöfst und ebenfalls mitnimmt, wobei nun das Lager C4 folgen mufs. In der anderen äufsersten Stellung sind die beiden Lager C1 C2 zusammengeschoben und die Lager C3 C4 besorgen die Führung., Dieses Spiel wiederholt sich bei jedem Hinoder Hergange der Mutter B. Die Spindel trägt demnach stets nur auf den _durch die Abstände der Lagerpaare bestimmten Längen frei und ist in diesen Abständen stets sicher gelagert und geführt.The mode of operation of this device is as follows: When the spindle A is driven in any sense, the threaded nut B moves forward in the relevant direction, while the bearings C 3 C 4 maintain their position. Here, the nut B abuts the bearing C 2 and takes it with it, with the bearing C 3 connected to C 2 following. The further the mother B goes, the closer she comes to the bearing C \ until she hits it and also takes it with her, with the bearing C 4 now having to follow. In the other extremest position, the two support C are pushed together 1 C 2 and the bearing C 3 C 4 get the lead., This game is repeated for each Hinoder Hergange the mother B. The spindle carries therefore always only on the _Due the distances of the Bearing pairs of certain lengths freely and is always safely stored and guided in these distances.
Die Vorrichtung kann in gleicher Weise auch bei langen, auf Durchbiegung in Anspruch genommenen Wellen u. dergl. Anwendung finden, wobei an Stelle einer Mutter ein anderes, die Verschiebung vermittelndes Element angeordnet wird.The device can be used in the same way for long, sagging Waves and the like are used, whereby instead of a mother another, the Displacement mediating element is arranged.
