Description

Gegenstand des Patentes 849 o49 ist eine längsbewegliche Zahnkupplung, bei der Kugeln als Übertragungsmittel zwischen gekrümmten, vorzugsweise hohlzylindrischen Zahnflanken beider Kupplungshälften liegen.The subject of patent 849 o49 is a longitudinally movable tooth coupling, in the case of balls as a transmission medium between curved, preferably hollow cylindrical The tooth flanks of both coupling halves lie.

Gegenstand der vorliegenden Erfindung ist eine derartige Zahnkupplung, die außer einer Längsverschiebung der Kupplungsteile gegeneinander auch geringe Verachsungen der Wellen um etwa 2 bisY zuläßt. Dies wird dadurch erreicht, daß die Kugeln im Ruhezustand der Kupplung ein gewisses Spiel haben und die gekrümmten Flächen so geneigt sind, daß die beim Lauf durch die Zentrifugalkraft nach außen geschleuderten Kugeln bei verachsten Wellen zur Mitte ausweichen können, ohne daß sie infolge der Reibung zwischen den Zahnflanken eingekeilt werden, so daß eine einwandfreie Drehmomentübertragung ohne überbeanspruchung der Zähne möglich ist.The subject of the present invention is such a tooth coupling, which apart from a longitudinal displacement of the coupling parts against each other also small Alignment of the waves by about 2 to Y allows. This is achieved in that the Balls have a certain amount of play when the clutch is at rest and the curved surfaces are inclined so that they are thrown outwards by centrifugal force while running Balls can move to the center in the case of dislocated waves without them as a result of the Friction wedged between the tooth flanks, so that a proper torque transmission is possible without overstressing the teeth.

In der Zeichnung ist in Abb. i ein Querschnitt der Kupplung dargestellt, in dem die Kugeln 3 in Mittelstellung gezeichnet sind. Die bogenförmigen Zähne der Gelenkteile i und 2 werden durch die Radien r = Kugeldurchmesser -I- Spiel vom mittleren Kugelkreis aus bestimmt.In the drawing, a cross section of the coupling is shown in Fig. I, in which the balls 3 are drawn in the middle position. The arched teeth of the Joint parts i and 2 are due to the radii r = ball diameter -I- clearance of the mean Ball circle determined from.

Abb:-2 zeigt die Kupplung während des Laufs. -Die Kugeln 3 sind durch die Zentrifugalkraft zur Anlage an die Mitnehmerflächen 4 und 5 gekommen und übertragen das Drehmoment vom Gelenkteil 2 auf das Gelenkteil i.Fig: -2 shows the clutch during the run. -The balls 3 are through the centrifugal force come to rest on the driver surfaces 4 and 5 and transferred the torque from the joint part 2 to the joint part i.

PATENTANSPRUCH: Zahnkupplung mit Kugeln zwischen konkav gekrümmten, vorzugsweise hohlzylindrischen Zahnflanken nach Patent 849 o49, dadurch gekennzeichnet, daß die Kugeln etwas Spiel zwischen den Zähnen haben und die Zahnflanken derart gekrümmt sind, daß die durch die Zentrifugalkraft in eine spielfreie Lage geschleuderten Kugeln bei gegenseitiger leichter Abwinkelung der gekuppelten Wellen nach innen so weit zurückgleiten können, daß sie das Drehmoment einwandfrei übertragen.PATENT CLAIM: Tooth coupling with balls between concave curved, preferably hollow cylindrical tooth flanks according to patent 849,049, characterized in that that the balls have some play between the teeth and the tooth flanks so are curved that the centrifugal force thrown into a backlash-free position Balls with mutual slight angling of the coupled shafts inwards can slide back so far that they transmit the torque properly.
