Description
Umlaufrädergetriebe. Es sind bereits Umlaufrädergetriebe bekannt, bei welchen mit Hilfe einer Sperrschnecke ein beliebiger Geschwindigkeitsunterschied zwischen treibender und .getriebener Welle erzeugt wird. Die praktische Verwertung derartiger Getriebe mußte bisher daran scheitern, daß es nicht gelang, die Bedingung der Selbstsperrung der Schnecke mit derjenigen einer möglichst geringen Kraft zum Antrieb der Schnecke zu vereinigen.Epicyclic gears. Epicyclic gears are already known in which with the help of a locking screw any speed difference is generated between the driving and the driven shaft. The practical utilization such a transmission had to fail so far because it did not succeed in the condition the self-locking of the screw with the lowest possible force to Unite drive of the worm.
Erfindungsgemäß wird dies dadurch erreicht, daß die Schnecke eine Steigung erhält, welche zwischen Selbstsperrung und Freilauf liegt, so daß die Antriebskraft der Schnecke unabhängig von der Leistung des Hauptmotors nahezu gleich Null wird.According to the invention this is achieved in that the screw a Get the slope, which lies between self-locking and freewheeling, so that the driving force the worm becomes almost zero regardless of the power of the main motor.
Die beiden Abbildungen zeigen eine Ausführungsform des Getriebes gemäß der Erfindung im Querschnitt und in der Seitenansicht.The two figures show an embodiment of the transmission according to of the invention in cross section and in side view.
Auf der Antriebswelle5, mit der der Hauptmotor verbunden ist, sitzt ein Zahnrad i, welches mit einem Zahnrad :2 in Eingriff steht, dessen Achse parallel zur Antriebs- und Arbeitswelle 5 bzw. 6 ist.It sits on the drive shaft5 to which the main motor is connected a gear i which meshes with a gear: 2, the axis of which is parallel to the drive and output shaft 5 and 6 respectively.
Die Leistungsübertragung von der Antriebswelle 5 auf die Arbeitswelle 6 geschieht durch ein festes Verbindungsstück 7. Das Zahnrad :2 steht ferner mit einem Zahnrad 3 (mit Innenverzahnung) in Eingriff, welches lose auf der Antriebswelle 5 sitzt. Das Zahnrad 3 trägt auf seiner Außenseite eine Schneckenradverzahnung, in welche die Reglerschnecke 4 greift. Letztere wird durch einen Steuermotor in angetrieben, dessen Regelung auf verschiedene Art in bereits bekannter Weise erfolgen kann. An Stelle des Steuermotors kann auch ein anderes geeignetes Getriebe Verwendung finden. Bei Stillstand der Schnecke 4 steht das Zahnrad 3 ebenfalls still. Der durch das Zahnrad 2 auf das Zahnrad 3 übertragene Reaktionsdruck wird von der Schnecke 4 abgefangen. Die Drehzahl des Tragzapfens des Zahnrades 2-entspricht der Drehzahl der Antriebswelle 5 und den Durchmessern der Zahnräder i, 2 und 3. Bei Stillstand des Zahnrades 3 erreicht somit die Arbeitswelle die größte Drehzahl. Durch Bewegung der Schnecke erhält auch das Zahnrad 3 eine bestimmte Drehzahl, so daß es dem Reaktionsdruck ausweicht. Die Folge .davon ist, daß bei gleichbleibender'Drehzahl von Zahnrad i die Drehzahl des Tragzapfens von Zahnrad 2 abnimmt, da die Drehrichtung des Zahnrades 3 entgegenges;etztder des Zahnrades i ist.The power transmission from the drive shaft 5 to the output shaft 6 is done by a fixed connector 7. The gear: 2 is also with a gear 3 (with internal teeth) in mesh, which loosely on the drive shaft 5 sits. The gear 3 has a worm gear toothing on its outside, into which the regulator worm 4 engages. The latter is controlled by a control motor in driven, which are regulated in various ways in a known manner can. Another suitable transmission can also be used instead of the control motor Find. When the worm 4 is at a standstill, the gear 3 is also at a standstill. The through the gear 2 transmitted to the gear 3 is reaction pressure from the worm 4 intercepted. The speed of the trunnion of the gear 2 corresponds to the speed of the drive shaft 5 and the diameters of the gears i, 2 and 3. At a standstill of the gear 3 thus the output shaft reaches the highest speed. Through movement the worm also receives the gear 3 at a certain speed, so that it meets the reaction pressure evades. The consequence of this is that with constant 'speed of gear i the speed of the trunnion of gear 2 decreases as the direction of rotation of the gear 3 is the opposite of that of gear i.
Die Steigung der Schnecke liegt zwischen Selbstsperrung und Freilauf, wobei die für einen brauchbaren und zugleich wirtschaftlichen Betrieb günstigsten Bedingungen dann gegeben sind, wenn die Schnecke eine Antriebskraft benötigt, die nahezu dem Wert Null gleichkommt, d. h. die Antriebskraft braucht nur einen zur Beschleunigung der Schneckenmasse notwendigen Wert zu erhalten.The pitch of the screw is between self-locking and free-running, whereby the most favorable for a usable and at the same time economical operation Conditions are given when the screw requires a driving force that is almost equal to zero, d. H. the driving force only needs one Acceleration of the screw mass to obtain the necessary value.
