Description
Wälzlager Die Erfindung bezieht sich auf ein Wälzlager, das mit elektrischen Schleifkontakten ausgerüstet ist. Die Lager können mit jeder Art von Wälzkörpern ausgelegt sein, sie können ein- oder mehrreihig sein sowie aus zwei oder mehr Tragringen zusammengesetzt sein. Ihre Größe ist beliebig, auch die größten Wälzlagerdrehverbindungen, die z. B. mittenfrei sind, können entsprechend der Erfindung ausgerüstet sein.Rolling bearing The invention relates to a rolling bearing with electrical Is equipped sliding contacts. The bearings can be used with any type of rolling element be designed, they can be single or multiple rows and two or more support rings be composed. They can be of any size, even the largest rolling bearing slewing rings, the z. B. are center-free, can be equipped according to the invention.
Erfindungsgemäß sind in einem oder mehreren Laufringen der Wälzlager unmittelbar oder unter Einbettung in einen isolierenden Werkstoff, wie z. B. Kunststoff, elektrisch leitende Teile, z. B. ein oder mehrere Drahtringe beliebigen Querschnitts, eingelegt. Von diesen Ringen kann an beliebiger Stelle Strom entnommen werden. Diese Leiter können je- doch auch teilweise abgedeckt sein, so daß an bestimmten Lagerstellen oder Lagerabschnitten die Stromabnahme oder umgekehrt die Stromzuführung unterbrochen ist. Eine weitere Verwendung dieser Leiter sieht die Einschaltung in die Zuführungsleitung des Antriebsmotors vor. Auf diese Weise ist es erfindungsgemäß möglich, den Antrieb nach Teildrehung bzw. -drehungen abzustellen oder auch in seiner Drehrichtung umzuschalten.According to the invention are in one or more races of the rolling bearings directly or embedded in an insulating material, such as. B. plastic, electrically conductive parts, e.g. B. one or more wire rings of any cross-section inserted. Current can be drawn from these rings at any point. These conductors may JE but also partially be covered, so that the current decrease or vice versa, the power supply is interrupted at certain bearings or bearing sections. Another use of these conductors is to connect them to the supply line of the drive motor. In this way it is possible according to the invention to switch off the drive after partial rotation or rotations or to switch over in its direction of rotation.
Ein besonders günstiges Anwendungsgebiet der erfindungsgemäßen Ausführung sind z. B. die Lagerungen für Schalttische.A particularly favorable field of application of the embodiment according to the invention are z. B. the bearings for indexing tables.
Mehrere Ausführungsbeispiele des Erfindungsgedankens sind in der Zeichnung dargestellt. Es zeigt Ab b. 1 einen Querschnitt durch ein Wälzlager, dessen Innenring aus Kunststoff besteht und in welchem die elektrischen Leiter unmittelbar eingelegt sind, Abb.2 einen Querschnitt durch ein Wälzlager aus Stahl, in welchem die elektrischen Leiter unter Einbettung in einen isolierenden Werkstoff angebracht sind, A b b. 3 einen Querschnitt durch ein Wälzlager, in welchem der Innenring aus Kunststoff zu einem Schleifringkörper verbreitert ist, A b b. 4 einen Querschnitt durch ein Wälzlager, in welchem eine stromführende überbrückung von einem Tragring auf den anderen vorgesehen ist, A b b. 5 eine Schrägansicht eines Teiles eines zweireihigen Kugellagers mit drei Ringen und in einem isolierenden Stoff eingebetteten Stromleitern.Several embodiments of the inventive concept are shown in the drawing. It shows Ab b. 1 shows a cross section through a roller bearing, the inner ring of which is made of plastic and in which the electrical conductors are directly inserted, Figure 2 shows a cross section through a roller bearing made of steel in which the electrical conductors are embedded in an insulating material, A b b . 3 shows a cross section through a roller bearing in which the inner ring made of plastic is widened to form a slip ring body, A b b. 4 shows a cross section through a roller bearing in which a current-carrying bridge is provided from one support ring to the other, A b b. 5 is an oblique view of part of a two-row ball bearing with three rings and current conductors embedded in an insulating material.
In den Abbildungen bezeichnet 1 den Außenring und 2 einen Innenring aus einem isolierenden Werkstoff, z. B. aus Kunststoff. Ein Innenring aus Stahl ist mit 2' bezeichnet. Zwischen beiden sind die Kugeln 3 eingesetzt. In dem Kunststoffring 2 sind ein oder mehrere elektrische Leiter, z. B. Drahtringe 4, eingelegt, auf deren vorstehendem Teil Schleifkontakte 5 oder Stromabnehmer 6 entlanggleiten. In dem Stahlring 2' sind die Drahtringe 4 in isolierenden Betten 7 eingelegt. In einem anderen Ausführungsbeispiel (Ab b. 3) ist der Innenring als Schleifringkörper 8 ausgeführt, in welchem die Schleifringe 4' eingelassen sind. Gemäß A b b. 5 wird z. B. die Stromzuführung 9 im Innenring angeordnet und die Überbrückung zum Außenring 1 über die Kontaktfeder 5 durchgeführt.In the figures, 1 denotes the outer ring and 2 an inner ring made of an insulating material, e.g. B. made of plastic. An inner ring made of steel is denoted by 2 '. The balls 3 are inserted between the two. In the plastic ring 2 one or more electrical conductors, for. B. wire rings 4, inserted, slide along sliding contacts 5 or current collector 6 on the protruding part. The wire rings 4 are placed in insulating beds 7 in the steel ring 2 ′. In another exemplary embodiment (from b. 3) the inner ring is designed as a slip ring body 8 in which the slip rings 4 'are embedded. According to A b b. 5 is z. B. the power supply 9 is arranged in the inner ring and the bridging to the outer ring 1 is carried out via the contact spring 5.
