Abstract
Description
Bei der vorliegenden Erfindung handelt es sich um eine elektromagnetisch betätigte Bremse nach dem Oberbegriff des Hauptanspruches. Nach dem Stand der Technik sind Bremsen bekannt, die durch reibschlüssigen Kontakt mit einer Bremsstange in der Lage sind, linear bewegte und/oder rotierende Massen aus definierter Geschwindigkeit und/oder definierter Drehzahl abzubremsen und zu halten.In the present invention is an electromagnetically actuated brake according to the preamble of the main claim. Brakes are known in the prior art, which are by frictional contact with a brake rod in a position to decelerate linearly moving and / or rotating masses of defined speed and / or speed defined and hold.
Eine derartige Bremse wird beispielsweise in
Für den Bewegungsablauf der beschriebenen Bremse nach dem Stand der Technik sind seitens des Federelements bzw. seitens des Elektromagneten große Hubwege erforderlich, was in der Praxis zu sehr langen Schaltzeiten sowohl beim Öffnen als auch beim Schließen der Bremse führt. Nachteilig an der beschriebenen Bauweise der Bremse nach dem Stand der Technik ist außerdem der große Bauraumbedarf vor allem seitlich der zu bremsenden Bremsstange.For the sequence of movement of the described brake according to the prior art, large travel distances are required on the part of the spring element or on the part of the electromagnet, which leads in practice to very long switching times both when opening and when closing the brake. A disadvantage of the described construction of the brake according to the prior art, in addition, the large space requirement especially the side of the brake rod to be braked.
Aufgabe der Erfindung ist es demnach, eine technische Verbesserung zum Stand der Technik vorzuschlagen, die eine weitere Steigerung der erzielbaren Bremskraft bzw. des erzielbaren Bremsdrehmoments ermöglicht, gleichzeitig die erforderlichen Schaltzeiten zum Öffnen und Schließen der Bremse deutlich verringert und eine vor allem seitlich der Bremsstange kompakte Bauweise ermöglicht.The object of the invention is therefore to propose a technical improvement to the prior art, which allows a further increase in the achievable braking force or the achievable braking torque, at the same time significantly reduces the required switching times for opening and closing the brake and especially on the side of the brake rod compact Construction allows.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass innerhalb der Bremse mehrere Elektromagneten mit zugeordneten Ankerscheiben vorzugsweise konzentrisch zur Bremsstange so hintereinander angeordnet werden, dass sich die durch die Elektromagneten auf die Ankerscheiben wirkenden Axialkräfte addieren und die gemeinsame Bewegung der Ankerscheiben auf eine innen konische Konusbuchse wirkt, die im Zusammenwirken mit einer außen konischen Spannzange eine Radialbewegung der Spannzange erzeugt, die auf der Oberfläche der Führungsstange eine Bremskraft und/oder ein Bremsdrehmoment bewirkt.According to the invention the object is achieved in that within the brake more electromagnets are arranged with associated armature discs preferably concentric to the brake rod so in succession that add the forces acting on the armature discs by the electromagnet axial forces and the common movement of the armature discs acts on an internally conical cone bush, which, in cooperation with an externally conical collet, generates a radial movement of the collet, which causes a braking force and / or a braking torque on the surface of the guide rod.
Weitere Merkmale der erfindungsgemäßen Linearbremse ergeben sich aus den Unteransprüchen.Further features of the linear brake according to the invention will become apparent from the dependent claims.
Anhand der nachstehenden Zeichnungen wird der Stand der Technik beschrieben und es werden die Funktionsweise und die Vorteile der erfindungsgemäßen elektromagnetisch betätigten Bremse näher erläutert.The state of the art will be described with reference to the following drawings, and the mode of operation and the advantages of the electromagnetically actuated brake according to the invention will be explained in more detail.
