Description
Zweck vorliegender Erfindung ist es ein narrensicher leicht schaltbares Wechselgetriebe mit stets in Eingriff bleibenden Zahnrädern, in kurzer Bauart und einfachen Bauteilen zu bauen.The purpose of the present invention is to build a foolproof, easily switchable change gear with always engaged gears, in a short design and with simple components.
Erreicht wird dies in vorliegender Erfindung gemäß anliegender Zeichnung dadurch, daß die auf einer Hohlwelle (a) einzeln lose drehbar gelagerten Wechselräder mittels einer in der Hohlwelle längsverschiebbar angeordneten Schaltstange (e) mit Ringnocke (f) und in den Bohrungen der Hohlwelle gelagerten Kugeln (g) wahlweise einzeln mit der Hohlwelle gekuppelt werden können.This is achieved in the present invention according to the attached drawing in that the change gears individually loosely rotatably mounted on a hollow shaft (a) by means of a shift rod (e) with an annular cam (f) and balls (g ) can optionally be coupled individually to the hollow shaft.
Zum Kuppeln eines der Wechselräder (b), (c) oder (d) wird die Schaltstange (e) so verschoben, daß die Ringnocke (f) die Kugeln (g) für das zu kuppelnde Wechselrad nach aussen in entsprechende Nuten (h) in dessen Bohrung gedrückt werden. Die nicht gekuppelten Wechselräder verdrängen ihre Kupplungskugeln nach innen und können sich so lose auf der Hohlwelle drehen.To couple one of the change gears (b), (c) or (d), the shift rod (e) is shifted so that the ring cam (f) pushes the balls (g) for the change gear to the outside into corresponding grooves (h) in whose hole are pressed. The non-coupled change gears displace their coupling balls inwards and can thus rotate loosely on the hollow shaft.
Um ein gleichmäßiges Tragen aller Kuppelelemente zu erzielen werden zweckmäßig für jedes Wechselrad 3 am Umfang gleichmäßig verteilte Kupplungskugeln (g) angeordnet. An Stelle der Kugeln (g) können auch Rollen oder Stifte verwendet werden.In order to achieve uniform wear of all coupling elements, coupling balls (g) distributed uniformly around the circumference are expediently arranged for each change gear 3. Instead of the balls (g), rollers or pins can also be used.
