Description
Die Erfindung betrifft eine Ummantelungsvorrichtung von rotierenden Bauteilen nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a casing device of rotating components according to the closer defined in the preamble of
Ummantelungsvorrichtungen von rotierenden Bauteilen werden häufig bei Getrieben eingesetzt, bei welchen Zahnräder teilweise in Schmiermitteln angeordnet sind und durch die Rotation dieser Zahnräder Panschverluste durch das Eintauchen der Zähne in die Schmiermitteloberfläche entstehen. Durch Ummantelungsvorrichtungen, welche zumindest teilweise die Zahnräder umgeben, können diese Panschverluste reduziert werden.Casing devices of rotating components are often used in transmissions in which gears are partially arranged in lubricants and caused by the rotation of these gears splintering losses by the immersion of the teeth in the lubricant surface. By sheathing devices, which at least partially surround the gears, these churning losses can be reduced.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Ummantelungsvorrichtung von rotierenden Bauteilen, insbesondere von Zahnräder, zu schaffen, welche auf einfache und kostengünstige Art herzustellen und ohne zusätzliche Bauteile in einem ortsfesten Gehäuse befestigbar ist.The present invention has for its object to provide a casing device of rotating components, in particular of gears, which can be produced in a simple and cost-effective manner and without additional components in a stationary housing can be fastened.
Diese Aufgabe wird mit einer Ummantelungsvorrichtung gelöst, welche die Merkmale des Patentanspruchs 1 aufweist. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved with a jacket device having the features of
Erfindungsgemäß weist die Ummantelungsvorrichtung rechtwinklig von der Drehachse des rotierenden Bauteils sich erstreckende Seitenwände auf, welche über einen dünnwandigen Verbindungskörper verbunden sind. Die Seitenwände weisen Erhebungen auf, welche in Vertiefungen ortsfester Bauteile, beispielsweise Gehäusewandungen eines Getriebegehäuses, eingreifen, um die Ummantelungsvorrichtung ortsfest in diesem Gehäuse zu halten. Es besteht die Möglichkeit, diese Erhebungen in unterschiedlichen Formen auszubilden, beispielsweise als zylindrische Erhebungen, welche in zylindrische Bohrungen in den ortsfesten Bauteilen eingreifen, oder als sphärische Erhebungen, beispielsweise halbkugelförmige Erhebungen, welche in kegelförmige Bohrungen eingreifen. Somit wird die Ummantelungsvorrichtung präzise im Getriebegehäuse angeordnet.According to the invention, the sheathing device has side walls extending at right angles from the axis of rotation of the rotating component, which are connected via a thin-walled connecting body. The side walls have elevations which engage in depressions of stationary components, for example housing walls of a gear housing, in order to hold the casing device stationary in this housing. It is possible to form these elevations in different forms, for example as cylindrical elevations, which engage in cylindrical bores in the stationary components, or as spherical elevations, for example, hemispherical elevations, which engage in conical bores. Thus, the sheath device is precisely arranged in the transmission housing.
In einer weiteren Ausgestaltungsform ist das Getriebegehäuse in zwei Getriebegehäusehälften geteilt, wodurch einerseits die Anbringung der Bohrungen auf eine einfache Weise erfolgen kann und die Montage, und somit das Eingreifen der Erhebungen in die Vertiefungen im Gehäuse, beim Zusammenfügen der beiden Gehäusehälften auf einfache Weise realisiert werden kann.In a further embodiment, the gear housing is divided into two gear housing halves, whereby on the one hand the mounting of the holes can be done in a simple manner and the assembly, and thus the engagement of the elevations in the recesses in the housing, are realized in a simple manner when joining the two housing halves can.
In einer weiteren Ausgestaltungsform besteht die Möglichkeit, den Verbindungskörper zwischen den Seitenwänden so auszugestalten, dass dieser in seinem elastischen Bereich so verformt werden kann, dass zur Montage der Abstand zwischen den Seitenwänden sich verringert, um die Erhebungen zu den Vertiefungen zu positionieren und anschließend durch die elastische Verformung des Verbindungskörpers die Erhebungen in die Vertiefungen eingreifen können.In a further embodiment, it is possible to design the connecting body between the side walls so that it can be deformed in its elastic region so that for mounting the distance between the side walls is reduced to position the elevations to the wells and then through the elastic deformation of the connecting body can engage the elevations in the wells.
In einer weiteren Ausgestaltungsform ist die Ummantelungsvorrichtung aus einem Kunststoffmaterial hergestellt, welches beispielsweise durch Spritzgußverfahren hergestellt werden kann.In a further embodiment, the casing device is made of a plastic material which can be produced for example by injection molding.
In einer weiteren Ausgestaltungsform umgreift die Ummantelungsvorrichtung das rotierende Bauteil zumindest teilweise, so dass das rotierende Bauteil zum Eingriff mit einem weiteren Zahnrad einer Kette oder eines Riemens angeordnet werden kann. Es besteht die Möglichkeit, die Ummantelungsvorrichtung einteilig oder aus mehreren Teilen herzustellen, wobei jedes Teil Seitenwände, ein Verbindungselement und Erhebungen aufweist.In a further embodiment, the sheathing device surrounds the rotating component at least partially, so that the rotating component can be arranged for engagement with a further toothed wheel of a chain or a belt. It is possible to produce the casing device in one or more parts, each part having side walls, a connecting element and elevations.
In einer weiteren Ausgestaltungsform weist mindestens eine Seitenwand an ihrer, der Drehachse zugewandten Begrenzung eine Ausnehmung auf, welche im Sinne eines Überlaufs überschüssiges Schmiermittel abfließen lassen kann. Die Ummantelungsvorrichtung kann beispielsweise bei im Sumpf angeordneten Vorgelegewellen eines Vorgelegegetriebes verwendet werden, es besteht auch die Möglichkeit, die Ummantelungsvorrichtung bei Differentialen zur Abschirmung des Tellerrades zu verwenden. Ebenso besteht die Möglichkeit, die Abschirmvorrichtung für rotierende Lamellenkupplungen zu verwenden.In a further embodiment, at least one side wall at its, the axis of rotation facing boundary has a recess, which can drain in the sense of an overflow excess lubricant. The sheathing device can be used for example in arranged in the marsh countershafts of a countershaft transmission, it is also possible to use the sheath device in differentials to shield the ring gear. It is also possible to use the shielding device for rotating multi-plate clutches.
