Description

  

      An    eine elektrische Maschine angebaute elektromagnetische     Bremslüftvorrichtung       Die Erfindung bezieht sich auf eine an  eine elektrische Maschine angebaute elektro  magnetische     Bremslüftvorrichtung    mit einem  das zweite Wellenende der Maschine ringför  mig umgebenden und die Erregerwicklung  einschliessenden Magnetgehäuse und einer mit  einer Bremsscheibe zusammenarbeitenden, un  ter Federdruck stehenden Ankerscheibe, wo  bei das     Magnetgehäuse,

      die     Hubbegrenzungs-          und.    Spanneinrichtung für die Bremsfedern  durch von der     Stirnseite    her in axialer Rich  tung     bedienbare    Schraubverbindungen ein  stellbar und     festspannbar    sind nach dem  Hauptpatent.

   Um im Notfall beim Aussetzen  der     elektromagnetischen    Bremslüftung die An  kerplatte von Hand von der     Bremsscheibe          wegzieher    und damit die Bremse lüften zu  können, sind bei dem im Hauptpatent be  schriebenen Ausführungsbeispiel der     Brems-          lüftvorrichtung    nach dem Hauptpatent an  der     Ankerplatte        Gewindebolzen        befestigt,    die  durch zwei Durchbohrungen des Magnet  gehäuses geführt sind und mit ihren Köpfen  in den äussern Stirnraum der     Bremse    ragen.  



  Die Erfindung hat die Aufgabe, die Hilfs  vorrichtung zum Lüften der Bremse von  Hand so zu gestalten, dass sie von einer zen  trisch gelegenen Stelle aus betätigt werden  kann. Erfindungsgemäss weist die     Hilfsbrems-          lüftvorrichtung    einen an der     Ankerscheibe     befestigten, das Wellenende der Maschine um  gebenden glockenförmigen Teil auf.    Die Erfindung soll an Hand des in der  Zeichnung dargestellten     Ausführungsbeispiels     näher erläutert werden.

   Auf dem der An  triebsseite abgekehrten Wellenende 1 einer  nicht weiter dargestellten elektrischen Ma  schine sitzt fest die Nabe 2 eines Tragkörpers  3     für    die mit den beiden Bremsbelägen 4 und  5 ausgestattete Bremsscheibe 6, die mittels       Bolzen    7 axial     verschiebbar    an dem Tragkör  per 3 befestigt ist:  An der Bremsscheibe 6 liegt die Anker  platte 8 eines aus dem ringförmigen, das Wel  lenende umgebenden Magnetgehäuse 9 und  der Erregerwicklung 10 bestehenden Elektro  magneten an. Eine Anzahl am Umfang gleich  mässig verteilter Federn 11 sucht die Anker  platte 8 gegen die Bremsscheibe 6 und die bei  den Bauteile gegen eine radiale Bremsfläche  12 des     Maschinenlagerschildes    13 zu drücken.

    An der Ankerplatte 8 ist ein das     Wellenende     1 mit der Nabe 2 des Tragkörpers 3 umgeben  der glockenförmiger Körper 14     befestigt,    der  am     Glockenboden    eine     Gewindebohrung    15 hat.  



  Die Erfindung bietet den Vorteil, dass die  Hilfseinrichtung zum Lüften der Bremse von  Hand gleichmässig am ganzen Umfang der  Ankerplatte     angreift.    Dadurch wird ein Ver  klemmen der     Ankerplatte    vermieden.



      The invention relates to an electromagnetic brake release device attached to an electric machine with a ringför mig surrounding the second shaft end of the machine and including the exciter winding and a magnet housing that works with a brake disc and is under spring pressure, where with the magnet housing,

      the stroke limitation and. Clamping device for the brake springs by screw connections that can be operated from the end face in the axial direction and can be tightened according to the main patent.

   In order to be able to pull the anchor plate away from the brake disc by hand when the electromagnetic brake release is interrupted and thus to release the brake, in the embodiment of the brake release device according to the main patent, threaded bolts are attached to the anchor plate through two through holes of the magnet housing and their heads protrude into the outer face of the brake.



  The invention has the task of making the auxiliary device for releasing the brake by hand so that it can be operated from a zen cally located point. According to the invention, the auxiliary brake release device has a bell-shaped part which is fastened to the armature disk and which surrounds the shaft end of the machine. The invention is to be explained in more detail with reference to the embodiment shown in the drawing.

   On the drive side facing away from the shaft end 1 of an electrical Ma machine not shown, the hub 2 of a support body 3 for the brake disc 6 equipped with the two brake linings 4 and 5, which is axially displaceably attached to the support body by 3 by means of bolts 7: On the brake disc 6 is the armature plate 8 of a ring-shaped, the Wel lenende surrounding magnet housing 9 and the field winding 10 existing electric magnets. A number of springs 11 evenly distributed around the circumference seeks the armature plate 8 to press against the brake disc 6 and the components against a radial braking surface 12 of the machine bearing plate 13.

    A bell-shaped body 14, which has a threaded hole 15 on the bell base, is attached to the anchor plate 8, surrounding the shaft end 1 with the hub 2 of the supporting body 3.



  The invention offers the advantage that the auxiliary device for releasing the brake by hand acts uniformly on the entire circumference of the anchor plate. This prevents the anchor plate from jamming.
