Abstract

The governor includes an infinitely-variable speed change gear with ratio from 1:1 to at least 1:6. The gear has at least one rotating rolling cage (I) in which an element with spherical curved friction surfaces engages with a driven component, also having spherical curved surfaces. At least two sets of the elements are formed of cylinders (XII). The two sets run in planes which are parallel to each other, at right angles to the common axis of rotation of the rolling cage and the drive component (VII), and intersecting it. The drive component can be pressed by an externally-operable lever- slide arrangement (VI,V) against one cylinder element set, while the other set is pressed against the driven component by means of spring pressure.

Description

Die Erfindung betrifft einen mechanischen Drehzahlregler mit einem stufenlos regelbaren Getriebe mit reibschlüssiger Kraftübertragung.The invention relates to a mechanical speed controller with a continuously variable adjustable transmission with frictional power transmission.

Die Aufgabe der Erfindung besteht darin, den Drehzahlregler so auszubilden, daß nur eine geringe Anpreßkraft bei präziser Steuerung erforderrlich ist, um den Reibschluß zwischen den kraftübertragenden Elementen des Getriebes zu erreichen.The object of the invention is to design the speed controller in such a way that that only a small contact pressure with precise control is required to the frictional connection between the force-transmitting elements of the transmission to reach.

Die Lösung dieser Aufgabe ist in dem Patentanspruch 1 angegeben.The solution to this problem is specified in claim 1.

Nach unserem Wissensstand wird vom Getriebebau derzeit kein ähnliches oder gleichwertiges stufenlos regelbares Universalgetriebe angeboten, welches folgende vorteilhafte Eigenschaften in sich vereint:To the best of our knowledge, gearbox construction is currently no similar or equivalent continuously variable universal transmission, which combines the following advantageous properties:

  • 1. Laufruhe wie ein Kugel- oder Rollenlager1. Smooth running like a ball or roller bearing
  • 2. Ruckfreie Drehzahländerung2. Smooth speed change
  • 3. Drehzahl konstant halten möglich3. Keeping the speed constant is possible
  • 4. Sehr hoher Wirkungsgrad4. Very high efficiency
  • 5. Verhältnismäßig geringer Andruck der Rollen (geringer Verschleiß)5. Relatively little pressure on the rollers (little wear)
  • 6. Selbstschmierend (Ölnebel) wartungsfrei6. Self-lubricating (oil mist) maintenance-free
  • 7. Unter- oder Übersetzung Rechts-Linkslauf.7. Under- or translation Right-left rotation.

Die Erfindung ist nachstehend anhand der Zeichnungen erläutert.The invention is explained below with reference to the drawings.

Fig. 2 Schnitt A-B in Fig. 1: Anordnung der Rollen XII, Kipphebelstangen IV und -form des Reglerringes zu erkennen. Fig. 2 section AB in Fig. 1: Arrangement of the rollers XII, rocker arm rods IV and shape of the regulator ring can be seen.

Dieses stufenlos regelbare Getriebe überträgt die Kraft mittels sechs Rollen XII, die in zwei Ebenen (2×3 Rollen) in einem Schwenkgehäuse III geführt werden. Diese Schwenkgehäuse III werden durch den mitlaufenden Reglerring II, der im teilbaren Rollenkorb I beweglich montiert ist, mittels Kipphebelstangen IV gesteuert. Ein ebenfalls mitlaufender Schieber V, der mit dem Hebel VI bedient wird, besitzt drei schrägverlaufende Nuten, mit denen die Kipphebelstangen IV zum Steuern des Reglerringes veranlaßt werden. Der Außenlaufring IX ist im Gegensatz zum Außenlaufring VIII horizontal verschiebbar, um ein Einstellen des Preßdruckes auf die Rollen XII mittels Feder X bewirken zu können. Das Betätigen des Hebels beim drehenden Getriebe bewirkt über den Schieber V, Kipphebelstangen IV und Reglerring II ein "Kippen" der Schwenkgehäuse III, was die Rollen XII zum gewindeartigen Auf- oder Ablaufen im Radius verablaßt, welches die stufenlose Regelung möglich macht. Um ein Überkippen der Rollen XII zu verhindern, sind im Reglerring II die Führungen für die Kugelköpfe außen begrenzt.This continuously variable transmission transmits the power by means of six XII rollers in two levels (2 × 3 rollers) in a swivel housing III. These Swivel housing III are separated by the revolving regulator ring II Roller basket I is movably mounted, controlled by rocker arm IV. One too moving slide V, which is operated with lever VI, has three oblique grooves with which the rocker arm IV to control the Controller ring are caused. The outer race IX is in contrast to the outer race VIII horizontally displaceable to adjust the pressure on the To be able to effect rollers XII by means of spring X. Operating the lever at rotating gear causes via slide V, rocker arm IV and regulator ring II a "tilting" of the swivel housing III, which makes the rollers XII thread-like Accumulated or drained in the radius, which allows the stepless regulation power. In order to prevent the rollers XII from tipping over, there are in the regulator ring II Guides for the ball heads limited on the outside.

Das Kernstück dieses Getriebes ist der aus technischen Gründen geteilte Rollenkorb I, der auch gleichzeitig ein Wellenende darstellt. Die zweite Welle VII (beidseitig gelagert) ist mit den gleichen Radien wie die beiden Außenlaufringe VIII und IX versehen. Die Drehbewegung wird durch sechs, in beweglich gelagerten Schwenkgehäusen III, Rollen übertragen. Ein Problem bestand nun auch darin, diese sechs Rollen so präzise steuern zu können, daß ein einwandfreies Regeln der Drehzahl möglich ist. Die Lösung fanden wir in einem im teilbaren Rollenkorb I beweglichen Reglerrring II, der mit Führungsnuten für die Schwenkgehäuse III versehen ist. Dieser Reglerring II wird mittels Kipphebelstangen IV, die über den Schieber V durch eine schräg verlaufende Nut bewegt werden, gesteuert. Der Schieber V wird durch den Hebel VI betätigt.The heart of this gearbox is the roller cage, which is divided for technical reasons I, which also represents a shaft end. The second wave VII (both sides is) with the same radii as the two outer races VIII and IX provided. The rotary movement is carried out by six swivel housings that are mounted in a movable manner III, roles transferred. One problem now was these six To be able to control rollers so precisely that a perfect regulation of the speed is possible. We found the solution in a moveable roller basket I Regulator ring II, which is provided with guide grooves for the swivel housing III. This Regulator ring II is by means of rocker arm IV, which via the slide V through a oblique groove can be moved, controlled. The slider V is by the Lever VI operated.

Dieses stufenlos regelbare Getriebe arbeitet ohne Zahnräder, Ketten oder Riemen. Sechs auf zwei Ebenen beweglich aufgehängte Rollen (im Rollenkorb), welche präzise gesteuert werden können, übertragen die Kraft von den Außenlaufringen zur Welle. This continuously variable transmission works without gears, chains or belts. Six rolls that can be moved on two levels (in the roll basket), which are precise can be controlled, transfer the power from the outer races to the Wave.  

Der mechanische Drehzahlregler ist universell vom Schiffbau über Werkzeugmaschine, Kraftfahrzeug bis zur Küchenmaschine einsetzbar und durch die relativ einfache Bauweise kostengünstig, eventuell auch aus Kunststoff, herzustellen.The mechanical speed controller is universal from shipbuilding to machine tools, Motor vehicle can be used up to the kitchen machine and by the relative simple construction inexpensive, possibly also made of plastic.

Vorteile: Geräuscharmut, ruckfreie Drehzahländerung, Rechts-Linkslauf, wartungsfrei, einfache Bedienung (ein Hebel) per Hand oder autom. Steuerung, sehr hoher Wirkungsgrad, platzsparend (eine Achse).Advantages: low noise, jerk-free speed change, right-left rotation, maintenance-free, simple operation (one lever) by hand or autom. Control, very high Efficiency, space-saving (one axis).
