Abstract
Description
Die Erfindung betrifft eine doppelt ausgeführte elektromagnetisch gelüftete Federdruckbremse mit den Merkmalen des Oberbegriffes des Anspruchs 1.The The invention relates to a double executed electromagnetically released spring-loaded brake the features of the preamble of claim 1.
Stand der Technik:State of the art:
In
der Patentschrift
Die Bremse wird hauptsächlich in der Bühnen- und Aufzugstechnik eingesetzt und muss deshalb sehr geräuscharm arbeiten.The Brake is mainly in the stage and elevator technology used and therefore must be very quiet work.
Im Horizontalbetrieb der Bremse entstehen nur geringe Geräusche, während im Vertikalbetrieb starke Schleifgeräusche entstehen können, welche in dieser Branche nicht akzeptiert werden.in the Horizontal operation of the brake produces only low noise while in the Vertical operation strong grinding noises can occur, which in this industry can not be accepted.
Aufgabenstellung:Task:
Der Erfindung liegt daher die Aufgabe zugrunde, eine solche Bremse zu schaffen, die ohne großen Bauaufwand und hohe Kosten Geräusche der Bremse eliminiert.Of the Invention is therefore based on the object to such a brake create that without big Construction costs and high noise costs of Brake eliminated.
Diese Aufgabe wird mit den Merkmalen des Patentanspruches 1 gelöst. Die als Ursache für Schleifgeräusche zwischen dem Rotor liegende Zwischenplatte wird durch entsprechende Gestaltung und Dimensionierung von Federn in einer Neutralstellung gehalten, in welcher sie weder im Horizontal-, noch im Vertikalbetrieb ein Schleifen an den jeweiligen Rotoren der Bremse A + B verursacht. Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.These The object is achieved by the features of claim 1. The as a cause of grinding noise between The intermediate plate lying on the rotor is by appropriate design and Dimensioning of springs held in a neutral position, in which they neither in horizontal nor in vertical operation a grinding caused at the respective rotors of the brake A + B. Other features The invention will become apparent from the dependent claims.
