Abstract
Description
Die Erfindung betrifft ein Getriebe.The The invention relates to a transmission.
In einem Getriebe wird üblicherweise als Schmierstoff Öl (Schmieröl) eingesetzt.In A gearbox is usually used as a lubricant oil (Lubricating oil) used.
Das Öl
haftet üblicherweise großflächig an den
Bauteilen des Getriebes an. Die
In einem Getriebe entstehen Verluste auch durch Reibung. Hinzu kann auch das Öl beitragen, insbesondere wenn es kalt ist.In A transmission also generates losses due to friction. Add to that also contribute to the oil, especially when it is cold.
Es ist Aufgabe der Erfindung, Reibungsverluste in einem Getriebe zu verringern.It Object of the invention, friction losses in a transmission to reduce.
Die Aufgabe wird dadurch gelöst, dass zumindest ein Bauteil des Getriebes an zumindest einer Stelle eine ölbabweisende Beschichtung aufweist.The Task is solved in that at least one component of the transmission at least one point a Ölbabweisende Coating has.
Somit tritt an der Stelle mit der Beschichtung kein nennenswerter Reibungsverlust durch Vermittlung von Öl auf und die gesamten Reibungsverluste im Getriebe verringern sich.Consequently no significant friction loss occurs at the point with the coating through mediation of oil and the total friction losses in the Gearboxes decrease.
Eine ölabweisende Beschichtung kann insbesondere unter Verwendung von Nanomaterial wie Nanoparikeln und Nanofasern gebildet sein.An oil repellent In particular, coating can be done using nanomaterial how nanoparticles and nanofibers are formed.
Man sollte bevorzugt für die ölabweisende Beschichtung eine solche Stelle oder solche Stellen auswählen, an denen die eigentliche Funktion des Öls der Schmierung nicht benötigt ist. Eine Schmierung ist insbesondere dann erforderlich, wenn ein Bauteil mit einem weiteren Bauteil zusammenwirkt und hierbei Berührkontakt hat, insbesondere solchen, um Kräfte und Drehmomente zu übermitteln. An diesen Stellen mit Berührkontakt ist das Öl sinnvoll eingesetzt. Bevorzugt wird man daher solche Stellen für die ölabweisende Beschichtung vorsehen, die bei einem Zusammenwirken des betreffenden Bauteils keinen Berührkontakt zu einem solchen weiteren Bauteil haben. An diesen Stellen ist das Öl nämlich nicht erforderlich, sondern kann für eine störende Reibkraft sorgen. Allerdings ist es auch möglich, an Stellen, an denen Berührkontakt zu einem weiteren Bauteil gegeben ist, eine ölabweisende Beschichtung, insbesondere zusätzlich zu der Beschichtung an Stellen ohne Berührkontakt, vorzusehen. Hierbei kann allerdings die ölabweisende Beschichtung lediglich einen kleinen Prozentsatz der Stellen mit Berührkontakt betreffen, z. B. insgesamt nicht mehr als 30%, und bevorzugt wird die ölabweisende Beschichtung so aufgebracht, dass das Öl nur in kleinen lokalen Einheiten wie Flecken oder Linien anhaftet. Die ölabweisende Beschichtung kann an Stellen mit Berührkontakt insbesondere so angeordnet sein, dass die Form und das Fließverhalten eines Schmierfilms durch die ölabweisenden Stellen beeinflusst, wenn nicht festgelegt wird. An Stellen ohne Berührkontakt kann ein ähnlicher Effekt bewirkt werden, wenn sie sich in einem Abstand von höchstens 3 mm, bevorzugt höchstens 1 mm von einer Stelle mit Berührkontakt entfernt befinden, was z. B. beim Zahnfuß oder am Zahnkopf eines mit Zähnen versehenen Elements der Fall ist. An diesen Stellen kann so das Verdrängen des Öls aus der Zahnlücke heraus erleichtert werden.you should be preferred for the oil-repellent coating to select such a body or bodies in which the actual function of the oil of lubrication is not needed is. Lubrication is required in particular when a component interacts with another component and touch contact has, in particular, to transmit forces and torques. At These places with touch contact the oil makes sense used. Preference is therefore given to such sites for provide the oil repellent coating, which in an interaction of the relevant component no contact with a contact have such another component. In these places, the oil is not required, but may be for a disturbing Frictional force provide. However, it is also possible in places where touch contact is given to another component is, an oil-repellent coating, in particular in addition to the coating in places without contact, provide. Here, however, the oil-repellent coating only a small percentage of the contact points concern, z. B. not more than 30% in total, and is preferred the oil-repellent coating applied so that the oil only clinging in small local units such as spots or lines. The oil repellent coating may be in contact with areas in particular be arranged so that the shape and the flow behavior a lubricating film influenced by the oil-repellent sites, if not set. In places without contact a similar effect can be effected when they are at a distance of at most 3 mm, preferably at most 1 mm away from a location with contact contact, what for. B. the tooth root or the tooth head with teeth provided element is the case. In these places can so Displacing the oil from the tooth gap be relieved out.
Die Erfindung wird bereits verwirklicht, wenn ein Getriebe mit zumindest einer Stelle mit ölabweisender Beschichtung bereitgestellt ist, auch wenn in dem Getriebe noch kein Öl befindlich ist. Üblicherweise wird jedoch spätestens im Betrieb Öl (insbesondere Schmieröl) in einem solchen Getriebe angeordnet sein. Nur in diesem Fall erweist die ölabweisende Beschichtung ihren Sinn.The Invention is already realized when a transmission with at least provided a location with oil repellent coating is, even if there is no oil in the transmission yet is. Usually, however, at the latest in operation oil (Lubricating oil in particular) be arranged in such a transmission. Only in this case, the oil-repellent coating proves their sense.
Nachfolgend werden bevorzugte Ausführungsformen der Erfindung unter Bezug auf die Zeichnung beschrieben, wobeifollowing preferred embodiments of the invention below With reference to the drawing, wherein

Die Erfindung kann grundsätzlich in jedem beliebigen Getriebe eingesetzt werden. Sie kann insbesondere auch in einem stufenlosen Geschwindigkeitswechselgetriebe eingesetzt werden, wobei die Beschichtung dann an den Stellen angeordnet wird, die nicht in Berührkontakt mit Scheiben eines Scheibensatzes stehen. Die Erfindung kann auch bei einem Verteilerdifferenzial gesetzt werden. Grundsätzlich kann an beliebigen Bauteilen eines Getriebes eine ölabweisende Beschichtung bereitgestellt sein, und zwar bevorzugt sowohl an dem jeweiligen Gehäuse als auch an Stellen von Bauteilen des Getriebes, die nicht in Berührkontakt mit anderen Bauteilen stehen. Die Beschichtung könnte sich theoretisch sogar bis zu diesen Stellen, die in Berührkontakt zu anderen Bauteilen stehen, hin erstrecken, wenn die Schmierung auf Teilbereiche der Berührbereiche konzentriert werden soll. Kleinteilig kann eine Beschichtung auf den Berührbereichen zu einer wunschgemäßen Formung des Schmierfilms beitragen.The Invention can basically in any gear be used. In particular, it can also be used in a stepless Speed change gear are used, the coating is then placed in the places that are not in touching contact with slices of a disc set. The invention can also be set at a distributor differential. in principle can be an oil repellent on any components of a transmission Be provided coating, preferably both on the respective housing as well as in places of components of Gearboxes that are not in touch with other components. The coating could theoretically even reach this one Points in contact with other components, extend when the lubrication concentrated on portions of the touch areas shall be. Small scale can be a coating on the touch areas to a desired shaping of the lubricating film contribute.
