Description

Patentbeschreibung: Bekannt sind Planetengetriebeg die aus den Grundelementen Sonnenrad, Kronenrad und Planetenrad (oder mehrere Planetenräder) bestehen. Die Herstellung dieser bekannten Planetengetriebe erfordert hochgenaue und daher kostspielige Bearbeitung, weil Maßungenauigkeiten zu Verklemmung und Bruch des ganzen Systems führen. Solche Planetengetriebe erfordern deshalb auch sorgfältige Wartung und Pflege.Patent description: Planetary gears are known from the basic elements Sun gear, crown gear and planet gear (or several planet gears) exist. the Production of these known planetary gears requires highly accurate and therefore expensive Machining because dimensional inaccuracies lead to jamming and breakage of the entire system to lead. Such planetary gears therefore also require careful maintenance and care.

Die Erfindung soll diese Schwierigkeiten beheben und die wirtschaftliche Herstellung eines anspruchlosen, hinreichend leistungsfähigen Planetengetriebes ermöglichen.The invention is intended to remedy these difficulties and to be economical Production of an undemanding, sufficiently powerful planetary gear enable.

Die Erfindung besteht darin, daß zwischen Sonnenrad (1) und Kronenrad (2) zwei Sätze Planetenräder (3)(4) angeordnet sind. Der Bewegungs- und Kraftschluß zwischen den beiden Planetenradsätzen (3)(4) ist durch ein Endlos-Band (5) hergestellt, das den inneren Planetenradeatz (4) umschließt, während die Planetenräder des äußeren Satzes (3) zwischen Endlos-Band (5) und Kronenrad (2) eingelegt sind. Jeder Planetenradsatz muß aus mindestens zwei Planetenrädern bestehen. Abb.1 zeigt ein Beispiel in dem beide Planetenradsätze aus je drei Planetenrädern bestehen.The invention consists in that two sets of planet gears (3) (4) are arranged between the sun gear (1) and crown gear (2). The movement and frictional connection between the two planetary gear sets (3) (4) is produced by an endless belt (5) which surrounds the inner planetary gear set (4), while the planetary gears of the outer set (3) between the endless belt (5 ) and crown gear (2) are inserted. Each planetary gear set must consist of at least two planetary gears. Fig. 1 shows an example in which both planetary gear sets consist of three planetary gears each.

Das Endlos-Band (5)kann je nach den technischen Erfordernissen, Leistungsübertragung oder Schlupflosigkeit, als Flachriemen, Keilriemen, Zahnriemen, Kette oder anders gewählt werden.Depending on the technical requirements, the endless belt (5) can transmit power or slippage, as flat belts, V-belts, toothed belts, chains or otherwise to get voted.

Die Vorteile des beschriebenen elastischen Planetengetriebes gegenüber den bekannten Planetengetrieben liegt darin: 1. da alle Planetenräder nur einseitig starr eingreifen, auf der anderen Seite aber im elastischen Endlos-Band liegen, werden Herstellungenauigkeiten während des Laufs durch das elastische Endloa-Band ausgeglichen. Das bedeutet kostengünstige Herstellung. 2. Das Endlos-Band ermöglicht die konstruktive Ausführung als Sollbruchstelle. Dadurch wird das angetriebene Agregat vor Bruch geschützt. 3. Einfache Instandsetzung durch Einlage eines neuen Endlos-Bandes. 4. Pflege und Wartung sind dadurch einfach.The advantages of the described elastic planetary gearbox compared to the known planetary gearboxes are: 1. Since all planetary gears only engage rigidly on one side, but on the other side are in the elastic endless belt, manufacturing inaccuracies are compensated for during the run by the elastic endless belt. That means inexpensive production. 2. The endless belt enables the structural design as a predetermined breaking point. This protects the driven unit from breakage. 3. Easy repair by inserting a new endless belt. 4. Care and maintenance are therefore easy.

Als eine mögliche konstruktive Lösung des elastischen Endlos-Bandes wird vorgeschlagen ein endloses Federband aus Stahl oder einem anderen federnden Material einzusetzen, in das eine gewünschte Zahnform eingebogen wird. (Abb.2). Ein solches Band ist kraftübertragend und weist radiale wie auch eine gewisse tangentiale Elastizität auf. 6 As a possible structural solution for the elastic endless belt, it is proposed to use an endless spring belt made of steel or another resilient material into which a desired tooth shape is bent. (Fig.2). Such a band is force-transmitting and has radial as well as a certain tangential elasticity. 6th
