Abstract
In der Anmeldung wird ein spielfrei vorgespanntes ein- oder mehrstufiges Miniplanetengetriebe 1 gezeigt mit einem zum Festkörpergelenk (2) ausgebildeten Planetenträger (3) der von einem Spannring (4) um die Achse (5) verdreht wird. Das Planetenzahnrad (1) sitzt auf einem U-förmig ausgebildeten Körper. Der U-förmig ausgebildete Körper entsteht wenn der Planetenträger durch trennende Aussparungen aufgespalten wird die nur noch an den Verjüngungen dem Festkörpergelenk (2) befestigt sind. Die Planetenstufen werden durch Zwischenscheiben (10) getrennt damit die Planetenzahnräder nicht verhaken.In the application, a backlash-biased one-stage or multi-stage mini planetary gear 1 is shown with a solid state joint (2) formed planet carrier (3) of a clamping ring (4) about the axis (5) is rotated. The planetary gear (1) sits on a U-shaped body. The U-shaped body is formed when the planet carrier is split by separating recesses which are attached only to the tapers the solid-body joint (2). The planetary stages are separated by washers (10) so that the planet gears do not get caught.

Allgemeines und Anwendungen:General and applications:
Im allgemeinen Maschinenbau und anderen Gebieten der Technik werden Planetengetriebe eingesetzt. Planetengetriebe haben Vorteile gegenüber anderen Getrieben. Planetengetriebe sollten möglichst spielfrei sein um am Abtrieb genau positionieren zu können wenn vom Antrieb des Planetengetriebes eine Position angefahren wird.In general engineering and other fields of technology planetary gears are used. Planetary gears have advantages over other transmissions. Planetary gears should be as free of play as possible to be able to position accurately on the output if a position is approached by the drive of the planetary gear.
Weil das Spiel im Planetengetriebe an mehreren Stellen innen und außen zwischen den Planeten und dem Hohlrad und zwischen den Planeten und dem Sonnenrad auftritt ist es besonders schwierig spielfreie Planetengetriebe herzustellen.Because the play occurs in the planetary gear in several places inside and outside between the planets and the ring gear and between the planet and the sun gear, it is particularly difficult to produce backlash-free planetary gear.
Je kleiner ein Planetengetriebe ist umso schwieriger und umso genauer und damit teurer ist es spielarm oder spielfrei zu bauen.The smaller a planetary gear is the more difficult and more accurate and therefore more expensive it is low-backlash or play-free build.
Lösung der Aufgabe:Solution of the task:
Ein bekanntes und das Spiel am Hohlrad und am Sonnenrad gleichzeitig ausgleichendes Prinzip ist das Verdrehen der Planetenachse im Mittelpunkt der Planeten senkrecht zur Mittelachse des Planetengetriebes.A well-known and the game at the ring gear and the sun gear simultaneously balancing principle is the rotation of the planetary axis in the center of the planets perpendicular to the central axis of the planetary gear.
Bei kleinen und sehr kleinen Planetengetrieben ist es nicht mehr möglich Gelenke mit Lager und Welle zur Verdrehung der Planetenachse zu gestalten.In small and very small planetary gears, it is no longer possible to design joints with bearings and shaft for rotating the planetary axis.
Es gibt grundsätzlich zwei Prinzipien das Spiel in Verzahnungen zu beseitigen.
Prinzip 1: Die Fertigung wird mit so geringem Spiel wie möglich hergestellt. Dann bleibt im Getriebe ein Restspiel. Es ist Spielarm.
Prinzip 2: Die Fertigung ist spielbehaftet und das Getriebe federnd ausgeführt und verspannt damit das Spiel ausgeglichen wird.There are basically two principles to eliminate the game in gearing.
Principle 1: The production is made with as little play as possible. Then there is a residual play in the transmission. It is play poor.
Principle 2: The production is subject to play and the gear is resilient and braced so that the game is compensated.
Hier wird Prinzip 2 gewählt und beschrieben.Here
Ein Planetenträger
In einer versetzt zur Drehachsenebene liegenden Ebene wird eine kreisförmige Aussparung (
Eine so verspannte Planetenstufe lässt sich schwer montieren weil die Planetenzahnräder nach außen federn. Damit trotzdem die Montage möglich ist muss die Planetenstufe im Hohlrad geführt eingebracht werden. Dazu dient ein zentrisch durch eine Bohrung in der Achse des Planetenträgers Abtrieb (
Damit die in mehreren Planetenstufen aneinander liegenden Planetenzahnräder nicht ineinander verhaken wird zwischen den Stufen eine Zwischenscheibe (
Auf diese Art können mehrstufige Planetengetriebe gebaut werden die mit einem definierten Drehmoment vorgespannt sind. Die Vorspannung des Spannringes bestimmt das Reibmoment und das Vorspannungsmoment des Planetengetriebes. In this way, multi-stage planetary gear can be built which are biased with a defined torque. The bias of the clamping ring determines the friction torque and the biasing torque of the planetary gear.
