Abstract

The shaft (1) from the motor drives the output shaft (2), which is directly connected to the coupling housing (9) via two pinions (4, 5) driven by a gearing on the drive shaft. The two pinions drive outer gearing sleeves (6, 7) connected by a strong spiral spring (8). The gear ratios between the two pinions and their sleeves differs by one tooth so that when the coupling is driven a reaction force tensions the spring and drives the housing, and hence the output shaft. When the housing is driven the effective tooth difference becomes zero. The coupling enables the input and output shafts to rotate relative to each other over several revolutions, thus providing a smooth power drive.

Description

Beschreibung der elastischen Kupplung Titel: Elastische Kupplung Anwendegebiet: Die Erfindung wird benötigt um träge Systeme zu beschleunigen.Description of the flexible coupling Title: Flexible coupling Area of application: The invention is needed to accelerate sluggish systems.

Zweck: Die elastische Kupplung ermöglicht den Anlauf eines Elektromotors und schließlich durch die stetig größer werdenden Kräfte beschleunigt sie das zu bewegende System und bewirkt so einen schonenden Anlauf.Purpose: The flexible coupling enables an electric motor to start up and finally through the steadily increasing forces it accelerates it moving system and thus causes a gentle start.

Stand der Technik: Vergleichbar mit der Erfindung ist die Hydro-Kupplung, jedoch nur mit der Wirkung und nicht mit der Eauart.State of the art: The hydraulic coupling is comparable to the invention, but only with the effect and not with the Eauart.

Ebenso gibt es elastische Kupplungen, bei denen die volle Kraft während einer 450 Drehzahldifferenz zwischen An- und Abtrieb auftritt. There are also elastic couplings, in which the full force during a 450 speed difference occurs between input and output.

Kritik des Standes der Tecknik: Die Hydro-Kupplung hat ein großes Trägheitsmoment.Criticism of the state of technology: The hydraulic coupling has a big one Moment of inertia.

Ebenso ist die Herstellung dieser Kupplung zu kostspielig. This coupling is also too expensive to manufacture.

Die bisher üblichen mechanischen Kupplungen lassen eine Winkeldrehung von maximal 450 zu. The previously common mechanical couplings allow an angular rotation from a maximum of 450 to.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, nach dem Anlaufen der Motoren eine Übertragung der vollen Kraft nach mehreren Umdrehungen zu ermöglichen.Task: The invention is based on the task after starting enable the motors to transfer full power after several revolutions.

Lösung: Zwei Zahnkränze erhalten eine zueinander relative Drehzahldifferenz, wodurch sie eine Verdrehfeder aufziehen.Solution: Two gear rims receive a relative speed difference to each other, whereby they wind up a torsion spring.

Beschreibung der Kupplung: 1) Antriebswelle mit Ritzel 2) Abtriebswelle 3) Zwischenwelle 4) Zwischenrad 5) Zwischenrad 6) Zahnkranz 7) Zahnkranz 8) Verdrehfeder 9) Gehäuse 10) Gleitlagering Die Antriebswelle 1 treibt die Zahnkränze 6 und 7 über die Zahnräder 4 und 5 an. Die Übersetzung zwischen 4 und 6 unterscheidet sich zur Übersetzung zwischen 5 und 7 mit einem Zahn pro Umdrehung der Zahnkränze.Description of the coupling: 1) input shaft with pinion 2) output shaft 3) Intermediate shaft 4) Intermediate gear 5) Intermediate gear 6) Ring gear 7) Ring gear 8) Torsion spring 9) Housing 10) Plain bearing ring The drive shaft 1 drives the sprockets 6 and 7 over the gears 4 and 5 on. The translation between 4 and 6 differs from Gear ratio between 5 and 7 with one tooth per revolution of the sprockets.

Durch diese relative Bewegung wird die Feder 8 langsam gespannt. Die Kraft steigt nun stetig an, wobei sich das Gehäuse 9, das mit der Welle 2 starr verbunden ist, in Bewegung setzt. The spring 8 is slowly tensioned by this relative movement. The force now increases steadily, with the housing 9, which is rigid with the shaft 2 connected, sets in motion.

Beginnt das Gehäuse zu routieren, wird die Welle 3 relativ zum Gehäuse langsamer. Dadurch wird die Drehzahldifferenz zwischen den Zahnkränzen 6 und 7 noch geringer, und die Drehzahldifferenz zwischen Welle 1 und 2 geht gegen 0. When the housing begins to rotate, the shaft 3 becomes relative to the housing slower. As a result, the speed difference between the ring gears 6 and 7 is still lower, and the speed difference between shaft 1 and 2 approaches 0.

Wird die Welle 1 nun abgebremst, arbeitet die Kupplung ebenso. Bei öfterem Drehzahlwechsel bremst die Kupplung elastisch ab. If the shaft 1 is now braked, the clutch works in the same way. at The clutch brakes elastically with frequent speed changes.
