Description

Die Erfindung bQZieht sich auf einen Preßluft-Zalinradmotor mit Planetenradantrieb, bei dem der Planetenkäfig zwischen den Planetenrädern gegenüber einer umlaufenden Wellenscheibe abgedichtet ist.The invention refers to a compressed air Zalinradmotor with planetary gear drive, in which the planetary cage between the planetary gears is opposite to a rotating one Wave washer is sealed.

Bei bekannten Zahnradmotoren ähnlicher Art verläuft die Dichtung zwischen den Planetenrädern und den dazugehörigen Gehäusegleitwänden . so, daß alle Stellen der Berührungsflächen zwischen den Planebenrädern dicht aufeinanderliegen. Bei Benutzung staubhaltiger Preßluft besteht die Gefahr, daß zwischen diese Gleitflächen Staubkörner und sonstige Fremdkörper gelangen. Diese Staubteile verursachen schon nach kurzer Zeit Zerstörungen an den Gleitflächen und damit Undichtigkeiten. Die sich daraus ergebenden Nachteile sind so schwerwiegend, daß die Lebensdauer solcher Zahnradmotoren nur eine verhältnismäßig kurze ist.In known gear motors of a similar type, the seal extends between the planetary gears and the associated sliding housing walls. so that all posts the contact surfaces between the plane gears lie close to one another. When using dusty compressed air there is a risk of dust grains between these sliding surfaces and other foreign bodies. These dust particles cause after a short time Time destruction of the sliding surfaces and thus leaks. The result of it The resulting disadvantages are so severe that the life of such gear motors is only a relatively short one.

Die erwähnten Mängel sind nach der Erfindung dadurch behoben, daß an den Stirnflächen des Käfigs Vertiefungen vorgesehen sind, die zur Aufnahme etwaiger durch die Preßluft mitgeführter Fremdkörper dienen. Diese Vertiefungen sind in der Lage, etwaige mit der Preßluft mitgeführte Fremdbestandteile, wie Staubkörnchen, aufzunehmen und zu sammeln, so daß sie gelegentlich abgeführt werden können, ohne Verschleißschaden anzurichten.The shortcomings mentioned are eliminated according to the invention in that on the end faces of the cage depressions are provided to accommodate any Foreign bodies carried along by the compressed air are used. These wells are in the Location, any foreign particles carried along with the compressed air, such as dust grains, absorb and collect so that they can occasionally be discharged without To cause wear damage.

In der Zeichnung ist eine Ausführungsform der Erfindung als Beispiel dargestellt.In the drawing is an embodiment of the invention as an example shown.

Abb.I ist ein Querschnitt nach der Linie A-A in Abb. 2; Abb. II ist ein Querschnitt nach der Linie B-B in Abb. i.Fig.I is a cross-section along the line A-A in Fig. 2; Fig. II is a cross-section along the line B-B in Fig. i.

Um das Sonnenrad i, das auf der Welle 2 drehbar gelagert ist, sind drei um die feststehenden Achsen 5 drehbare Planetenräder 3 in dem feststehenden Käfig 4 angeordnet. Die Planetenräder sind von dem innenverzahnten Außenrad 6 umschlossen. Sie kämmen sowohl mit dem Sonnenrad i als auch mit der Verzahnung des Außenrades 6. An diesem ist über die Wellenscheibe i i die Welle 2 befestigt, von deren außenliegendem Wqllenstumpf 7 die Leistung des Motors abgenommen wird. Das Außenrad 6 mit der Wellenscheibe i i ist von dem Gehäuse 8 umschlossen. Das Sonnenrad i und die Planetenräder 3 liegen über ihren nicht im Eingriff stehenden Umfang mit einem ganz geringen Spiel in den zylindrischen Ausnehmungen 9 und io des Käfigs 4. Die Stirnflächen der Antriebsräder werden einerseits durch die Wandplatte des Käfigs 4, anderseits durch die Wellenscheibe i i abgedichtet. In der Wandplatte des Käfigs 4 ist der Luftzuführungskanal 12 angebracht, der sich in Form der Zuleitungen 13 in dem Käfig fortsetzt und an den Stellen 14 und 15 ausmündet, wo die Planetenräder in das Sonnen- und das Außenrad eingreifen. Für den Luftaustritt sind die Auslaßleitungen 16 vorgesehen, die an den Auslaßstellen i9 und 2o ansetzen und über dem Auslaßkanal 17 des Käfigs 4 mit dem Auspuff 18 in Verbindung stehen.To the sun gear i, which is rotatably mounted on the shaft 2, are three planet gears 3 rotatable about the fixed axes 5 in the fixed one Cage 4 arranged. The planet gears are enclosed by the internally toothed outer gear 6. They mesh with both the sun gear i and the teeth of the outer gear 6. The shaft 2 is fastened to this via the shaft washer i i, from the outer one Wqllenstumpf 7 the power of the engine is decreased. The outer wheel 6 with the wave washer i i is enclosed by the housing 8. The sun gear i and the planet gears 3 are located beyond their non-engaged scope with very little play in the cylindrical recesses 9 and io of the cage 4. The end faces of the drive wheels are on the one hand by the wall plate of the cage 4, on the other hand by the wave washer i i sealed. In the wall plate of the cage 4, the air supply duct 12 is attached, which continues in the form of supply lines 13 in the cage and at points 14 and 15 opens out where the planet gears mesh with the sun and outer gears. For the air outlet, the outlet lines 16 are provided, which are at the outlet points Position i9 and 2o and above the outlet port 17 of the cage 4 with the exhaust 18 in Connected.

An den Stirnflächen des Käfigs 4 sind taschenartige Vertiefungen 22 für die Aufnahme der durch - die Preßluft mitgeführten Staubteilchen und sonstiger.Fremdkörper ausgespart.Pocket-like depressions 22 are provided on the end faces of the cage 4 for the absorption of the dust particles and other foreign bodies carried along by the compressed air left out.
