Abstract
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 Wälzlagereinheit mit einer Baueinheit bekannt. Die Aufgabe der Erfindung besteht insbesondere darin, eine gattungsgemäße Wälzlagereinheit bereitzustellen, welche eine hohe Effizienz aufweist. Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Unteransprüchen entnommen werden können.It is a rolling bearing unit with a unit known. The object of the invention is in particular to provide a generic rolling bearing unit, which has a high efficiency. 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 Wälzlagereinheit, insbesondere einem Wälzkörper, mit wenigstens einer Baueinheit. The invention relates to a rolling bearing unit, in particular a rolling element, with at least one structural unit.
Es wird vorgeschlagen, dass die Baueinheit dazu vorgesehen ist, in wenigstens einem Bereich ihrer unmittelbaren Umgebung ein magnetisches Feld zu erzeugen, welches eine Anziehung eines Eisenspahns mit einer Kraft bewirkt, welche größer ist als die Gewichtskraft des Eisenspahns. Unter „vorgesehen“ soll insbesondere speziell ausgelegt und/oder ausgestattet und/oder speziell programmiert verstanden werden. Unter einem "Eisenspahn“ soll insbesondere ein Teilchen aus dem chemischen Element Eisen verstanden werden, welches eine maximale Erstreckungslänge von wenigstens 1 µm und vorzugsweise höchstens 3 mm aufweist. Mit einer erfindungsgemäßen Ausgestaltung kann eine Wälzlagereinheit bereitgestellt werden, welche eine hohe Effizienz aufweist. Insbesondere kann eine lange Lebensdauer der Wälzlagereinheit erreicht werden. Im besonderen können Partikel, welche bei einem Betrieb der Wälzlagereinheit dieser an Laufflächen und Laufbahnen Beschädigungen zufügen können, von der Baueinheit angezogen und damit von beschädigbaren Teilen, wie einem Wälzkörper oder einer Lauffläche, ferngehalten werden.It is proposed that the assembly is intended to generate in at least a portion of its immediate vicinity a magnetic field which causes an attraction of an iron whip with a force which is greater than the weight of the iron whip. By "intended" is intended to be understood in particular specially designed and / or equipped and / or specially programmed. An "iron impulse" is to be understood in particular as meaning a particle of the chemical element iron which has a maximum extension length of at least 1 μm and preferably not more than 3 mm With an embodiment according to the invention, a rolling bearing unit can be provided which has a high efficiency In particular, particles which can cause damage to running surfaces and raceways during operation of the roller bearing unit can be attracted to the assembly and thus kept away from damageable parts, such as a rolling body or a running surface.
Ferner wird vorgeschlagen, dass die Wälzlagereinheit wenigstens ein Wälzkörperelement mit einer Lauffläche und mit wenigstens einer Ausnehmung aufweist, in welcher die Baueinheit wenigstens teilweise angeordnet ist. Dadurch kann eine lange Lebensdauer des Wälzkörperelements erreicht werden.It is also proposed that the rolling bearing unit has at least one rolling body element with a running surface and with at least one recess in which the assembly is at least partially arranged. Thereby, a long life of the rolling element can be achieved.
Vorzugsweise weist die Wälzlagereinheit wenigstens ein Magnetfeldfokussierungselement auf, welches mit dem Wälzkörperelement verbunden ist und dazu vorgesehen ist, das von der Baueinheit erzeugte Magnetfeld an einem Ende der Ausnehmung zu fokussieren. Unter einem "Magnetfeldfokussierungselement, welches dazu vorgesehen ist, das von der Baueinheit erzeugte Magnetfeld an einem Ende der Ausnehmung zu fokussieren“, soll insbesondere ein Element verstanden werden, welches in einem Zustand, in welchem es mit dem Wälzkörperelement verbunden ist und vorzugsweise an dieses montiert ist, bewirkt, dass ein von der Baueinheit erzeugtes Magnetfeld an dem Ende der Ausnehmung betragsmäßig größer ist als in einem Zustand, in welchem das Element mit dem Wälzkörperelement unverbunden ist und insbesondere von dem Wälzkörperelement demontiert ist. Jedoch kann eine hohe auf Schmutzpartikel wirkende Anziehungskraft erreicht werden. Preferably, the rolling bearing unit has at least one magnetic field focusing element, which is connected to the rolling element and is intended to focus the magnetic field generated by the unit at one end of the recess. By a "magnetic field focusing element, which is intended to focus the magnetic field generated by the unit at one end of the recess", is to be understood in particular an element which is in a state in which it is connected to the rolling element and preferably mounted on this , causes a magnetic field generated by the assembly to be larger in magnitude at the end of the recess than in a condition where the member is unconnected to the rolling element and disassembled from the rolling element in particular become.
Ferner kann die Wälzlagereinheit insbesondere bei Transportvorrichtungen im Bergbau oder bei Lagereinrichtungen von Schiffen oder insbesondere bei Großgetrieben eingebaut sein.Furthermore, the rolling bearing unit can be installed in particular in transport devices in mining or storage facilities of ships or in particular in large gearboxes.
Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In den Zeichnungen sind Ausführungsbeispiele 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 drawings, embodiments of the invention are 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.
