Abstract
Die Erfindung geht aus von Vorrichtung mit zumindest einer Ausgleichswelle (10) und wenigstens einem ersten Wälzlager (12), das an einer drehbaren Lagerung der Ausgleichswelle zumindest mitwirkt. Es wird vorgeschlagen, dass das erste Wälzlager als mehrreihiges Kugellager ausgebildet ist.The invention relates to a device having at least one balance shaft (10) and at least one first roller bearing (12), which at least cooperates on a rotatable mounting of the balance shaft. It is proposed that the first rolling bearing is designed as a multi-row ball bearing.
Description
Die Erfindung geht aus von einer Vorrichtung nach dem Oberbegriff des Anspruchs 1. The invention relates to a device according to the preamble of claim 1.
Es ist eine Vorrichtung mit einer Ausgleichswelle und Nadellagern, welche die Ausgleichswelle drehbar lagern, bekannt. Ferner ist eine Vorrichtung mit einer Ausgleichswelle bekannt, welche von Wälzlagern drehbar gelagert. Eines der Wälzlager ist dabei ein Kugellager. Des Weiteren gehören durch Gleitlager drehbar gelagerte Ausgleichswellen zum Stand der Technik. It is a device with a balance shaft and needle bearings, which store the balancer shaft rotatably known. Furthermore, a device with a balance shaft is known which rotatably supported by rolling bearings. One of the rolling bearings is a ball bearing. Furthermore include by plain bearings rotatably mounted balance shafts to the prior art.
Die Aufgabe der Erfindung besteht insbesondere darin, eine gattungsgemäße Vorrichtung mit einer effizienten und geräuscharmen Lagerung bereitzustellen. Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Unteransprüchen entnommen werden können. The object of the invention is in particular to provide a generic device with an efficient and quiet storage. The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention can be taken from the dependent claims.
Die Erfindung geht aus von einer Vorrichtung mit zumindest einer Ausgleichswelle und wenigstens einem ersten Wälzlager, das an einer drehbaren Lagerung der Ausgleichswelle zumindest mitwirkt. The invention is based on a device having at least one balance shaft and at least one first rolling bearing, which at least participates in a rotatable mounting of the balance shaft.
Es wird vorgeschlagen, dass das erste Wälzlager als mehrreihiges Kugellager ausgebildet ist. Mit einer erfindungsgemäßen Ausgestaltung kann eine effiziente und geräuscharme Lagerung erreicht werden. Insbesondere kann im Vergleich dazu, dass das Wälzlager als Nadellager ausgebildet ist, eine Reduzierung der Lautstärke der verursachten Geräusche erreicht werden. Ferner kann vermieden werden, dass als Wälzkörper fungierende Nadeln schränken und dabei Geräusche verursachen. Insbesondere kann eine Reduzierung von auftretender Reibung im Vergleich zu einer Lagerung mittels wenigstens eines Gleitlagers erreicht werden. It is proposed that the first rolling bearing is designed as a multi-row ball bearing. With an embodiment of the invention, an efficient and low-noise storage can be achieved. In particular, compared to the fact that the rolling bearing is designed as a needle bearing, a reduction in the volume of the noise caused can be achieved. Furthermore, it can be avoided that acting as rolling elements needles restrict and thereby cause noise. In particular, a reduction of occurring friction compared to a storage by means of at least one sliding bearing can be achieved.
Vorzugsweise weist die Vorrichtung wenigstens ein zweites Wälzlager auf, welches an der drehbaren Lagerung der Ausgleichswelle mitwirkt. Besonders bevorzugt ist das zweite Wälzlager als mehrreihiges Kugellager ausgebildet. Preferably, the device has at least one second roller bearing, which cooperates with the rotatable mounting of the balance shaft. Particularly preferably, the second rolling bearing is designed as a multi-row ball bearing.
Ferner wird vorgeschlagen, dass die drehbare Lagerung der Ausgleichswelle frei von Gleitlagern ist. It is also proposed that the rotatable mounting of the balance shaft is free of plain bearings.
Mit Vorteil ist die drehbare Lagerung der Ausgleichswelle frei von Nadellagern. Außerdem wird vorgeschlagen, dass die Vorrichtung eine Kurbelwelle aufweist und die Ausgleichswelle dazu vorgesehen ist, eine Unwucht der Kurbelwelle auszugleichen. Advantageously, the rotatable mounting of the balance shaft is free of needle bearings. It is also proposed that the device has a crankshaft and the balance shaft is provided to compensate for an imbalance of the crankshaft.
Des Weiteren wird ein Kraftfahrzeug mit einer vorstehend beschriebenen Vorrichtung vorgeschlagen. Furthermore, a motor vehicle with a device described above is proposed.
Ferner wird ein Verfahren zum Ausgleichen einer Unwucht, insbesondere mit einer vorstehend beschriebenen Vorrichtung, vorgeschlagen, bei welchem sich eine Ausgleichswelle dreht und dabei zumindest von einem mehrreihigen Kugellager drehbar gelagert wird. Further, a method for compensating an imbalance, in particular with a device described above, proposed, in which a balance shaft rotates and is rotatably supported at least by a multi-row ball bearing.
Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Zeichnungen, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen. Further advantages emerge from the following description of the drawing. In the drawing, an embodiment of the invention is shown. The drawings, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.
Die Vorrichtung ist Teil eines Automobils. Außerdem weist die Vorrichtung eine Kurbelwelle (nicht dargestellt) auf. Die Ausgleichswelle dreht sich, wenn die Kurbelwelle sich dreht und gleicht dadurch eine Unwucht der Kurbelwelle aus. The device is part of an automobile. In addition, the device has a crankshaft (not shown). The balance shaft rotates as the crankshaft rotates, thereby compensating for an unbalance in the crankshaft.
