Abstract
Es sind schon Zahnräder bekannt, mit einem Nabenelement und einem mit dem Nabenelement über Federelemente verbundenen Zahnkranz. Beim aufeinander Abwälzen dieser Zahnräder entstehen Geräusche.
Bei dem erfindungsgemäßen Zahnrad werden die Geräusche beim Abwälzen des Zahnrades verringert.
Erfindungsgemäß ist vorgesehen, dass die Federelemente (6) jeweils zumindest eine Ausbuchtung (7) aufweisen, die zum Nabenelement (2) oder zum Zahnkranz (3) hin offen ausgebildet ist.
There are already gears known, with a hub member and connected to the hub member via spring elements ring gear. When these gears roll on each other noise.
In the gear according to the invention, the noise when rolling the gear are reduced.
According to the invention, it is provided that the spring elements (6) each have at least one bulge (7), which is designed to be open towards the hub element (2) or the toothed rim (3).
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Zahnrad nach der Gattung des Hauptanspruchs.The invention relates to a gear according to the preamble of the main claim.
Es sind schon Zahnräder aus der
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Zahnrad mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass weniger Geräusche beim Abwälzen des Zahnrades entstehen, indem die Federelemente des Zahnrades jeweils zumindest eine Ausbuchtung aufweisen, die zum Nabenelement oder zum Zahnkranz hin offen ausgebildet ist. Durch die Federelemente kann der Zahnkranz des Zahnrades beim Abwälzen der Zähne elastisch federn, was die Laufgeräusche verringert.The gear according to the invention with the characterizing features of the main claim has the advantage that less noise during rolling of the gear formed by the spring elements of the gear each have at least one bulge, which is formed open to the hub member or the ring gear. By the spring elements of the sprocket of the gear can elastically spring when rolling the teeth, which reduces the running noise.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Zahnrads möglich.The measures listed in the dependent claims advantageous refinements and improvements of the main claim gear are possible.
Besonders vorteilhaft ist, wenn die Federelemente jeweils mehrere Ausbuchtungen aufweisen, die in Richtung der Längserstreckung des jeweiligen Federelementes gesehen abwechselnd entweder zum Nabenelement oder zum Zahnkranz hin offen ausgebildet sind. Auf diese Weise werden die Geräusche beim Abwälzen noch weiter verringert.It is particularly advantageous if the spring elements each have a plurality of bulges, which are seen in the direction of the longitudinal extent of the respective spring element alternately open either to the hub member or the ring gear out. In this way, the noise when rolling be reduced even further.
Nach einer vorteilhaften Ausführung weisen die Ausbuchtungen der Federelemente jeweils zwei in radialer Richtung bezüglich einer Zahnradachse verlaufende Schenkel und einen die Schenkel verbindenden Bogen auf. Auf diese Weise ergeben sich jeweils mäanderförmige Federelemente mit guten Geräuschdämpfungs-Eigenschaften.According to an advantageous embodiment, the bulges of the spring elements each have two legs extending in the radial direction with respect to a gear axis and an arc connecting the legs. In this way, respectively meandering spring elements with good noise damping properties arise.
Weiterhin vorteilhaft ist, wenn zumindest eines der Federelemente entlang seines Verlaufes eine konstante Wandstärke oder unterschiedliche Wandstärken aufweist. Auf diese Weise kann die Federsteifigkeit der einzelnen Federelemente optimal eingestellt werden.It is also advantageous if at least one of the spring elements along its course has a constant wall thickness or different wall thicknesses. In this way, the spring stiffness of the individual spring elements can be optimally adjusted.
Sehr vorteilhaft ist es, wenn die Federelemente identisch oder unterschiedlich, insbesondere hinsichtlich der Form, der Anzahl oder der Wandstärke der Ausbuchtungen unterschiedlich, ausgebildet sind. Auf diese Weise kann die Federsteifigkeit bzw. das Federverhalten der Federelemente optimal eingestellt werden.It is very advantageous if the spring elements are identical or different, in particular with regard to the shape, the number or the wall thickness of the bulges differently. In this way, the spring stiffness or the spring behavior of the spring elements can be optimally adjusted.
Nach einer vorteilhaften Ausführung ist das Zahnrad einstückig aus einem Material, insbesondere Stahl, hergestellt. Auf diese Weise ist es bei Stahl-Zahnrädern möglich, auf erfindungsgemäße Weise Laufgeräusche zu vermindern.According to an advantageous embodiment, the gear is made in one piece from a material, in particular steel. In this way it is possible with steel gears to reduce running noise according to the invention.
Desweiteren vorteilhaft ist, wenn das erfindungsgemäße Zahnrad mittels 3D-Druck hergestellt ist, da sich die erfindungsgemäßen Ausbuchtungen der Federelemente auf diese Weise sehr einfach herstellen lassen. Der 3D-Druck ermöglicht es, das Zahnrad mit den mäanderförmigen Federelementen aus Stahl einstückig herzustellen.Furthermore, it is advantageous if the gear according to the invention is produced by means of 3D printing, since the bulges of the spring elements according to the invention can be produced in this way very easily. The 3D printing makes it possible to manufacture the gearwheel in one piece with the meander-shaped steel spring elements.
