Description

Bei Kegelbremsen, die zwischen Antriebswelle und anzutreibender Maschine angeordnet sind und selbsttätig bei Fortfall des antreibenden Drehmomentes einfallen, wird die Bremskraft durch eine Feder erzeugt, während das Lösen der Bremse durch eine axial wirkende Kraft erfolgt, die über Schrägflächen durch das Drehmoment der antreibenden Welle hervorgerufen wird. Die Wirkungsweise solcher Kegelbremsen bedingt, daß die beiden Bremskonen stets gut zueinander zentriert und nachstellbar sind. Schon bei Montage der Bremseinheit ist eine Einstellbarkeit eines der beiden Konen notwendig, um Ungenauigkeiten der Bearbeitung und Maßdifferenzen auszugleichen. Im Betrieb muß von Zeit zu Zeit einer der beiden Konen nachgestellt werden, um die Abnutzung auszugleichen.With cone brakes, those between the drive shaft and the machine to be driven are arranged and apply automatically when the driving torque is lost, the braking force is generated by a spring while releasing the brake through an axially acting force takes place, which is generated via inclined surfaces by the torque of the driving wave is caused. The mode of action of such cone brakes requires that the two brake cones are always well centered and adjustable to one another. One of the two cones can already be adjusted when the brake unit is installed necessary to compensate for inaccuracies in processing and dimensional differences. During operation, one of the two cones must be readjusted from time to time in order to prevent the To compensate for wear and tear.

Bei bekannten Nachstelleinrichtungen mittels Stellschrauben ist ein genau zentrisches Einstellen bzw. axiales Verschieben ohne Schiefstellen des Bremskegels von der Geschicklichkeit des Menschen abhängig. Bekanntgewordene Verbesserungen, z. B. durch Führung des Bremskegels in schrägen Nuten, sind fertigungstechnisch teuer und zu grob, um die erwünschte Genauigkeit beim Einstellen zu gewährleisten.In known adjusting devices by means of adjusting screws is a precisely centric setting or axial shifting without tilting the brake cone depending on the skill of the person. Known improvements z. B. by guiding the brake cone in inclined grooves, are manufacturing technology expensive and too coarse to ensure the desired accuracy when setting.

Gegenstand der Erfindung ist eine Feineinstellung mittels Gewindes, welches auf den Bremskegel geschnitten ist und durch Verdrehen eines daraufsitzenden Ringes mit Innengewinde den Kegel in Axialrichtung verstellt. Dabei ist die Gewindesteigung so gewählt, daß zu einem kleinen Axialweg des Konus ein großer Drehwinkel des Ringes gehört. Der Bremskegel wird durch axiale Führungen gehindert, sich mitzüdrehen. Der Gewindering wird nach der Einstellung festgeklemmt.The subject of the invention is a fine adjustment by means of a thread, which is cut on the brake cone and by twisting one sitting on it Ring with internal thread adjusts the cone in the axial direction. Here is the thread pitch chosen so that a large angle of rotation of the ring for a small axial travel of the cone heard. The brake cone is prevented from turning with axial guides. The threaded ring is clamped after the adjustment.

In Abb. I und 2 ist ein Ausführungsbeispiel schematisch im Schnitt dargestellt. Darin bedeutet I antreibende Welle, 2 abtreibende Welle, 3 Paßfeder, 4 Gleitfeder, 5 antreibende Hohlwelle, 6 antriebsseitige Zahnkupplungshälfte (I), 2 abtriebsseitige Zahnkupplungshälfte (2), 8 Radial- und Axiallager für 5, 9 Radial- und Axiallager für 2, Io umlaufende Bremsscheibe, auf 2 axial verschiebbar, II Druckfeder, auf Io wirkend, I2 Federteller, I3 Bremsbelag auf Io, I4 Ventilatorflügel, I5 Gehäusedeckel, I6 Ring mit Bremskonus und Nachstellgewinde, I7 Gehäuse, I8 Kopfschrauben für Gehäuse und Verdrehungssicherung für I6, I9 Gehäuse der anzutreibenden Maschine, 2o Löcher in I7 für Lüftung und Nachstellen der Bremse.In Fig. I and 2 an embodiment is shown schematically in section shown. I means driving shaft, 2 driving shaft, 3 key, 4 sliding spring, 5 driving hollow shaft, 6 drive-side tooth coupling half (I), 2 gear coupling halves on the output side (2), 8 radial and axial bearings for 5, 9 radial and axial bearing for 2, Io circumferential brake disc, axially displaceable on 2, II compression spring, acting on Io, I2 spring plate, I3 brake lining on Io, I4 fan blades, I5 housing cover, I6 ring with brake cone and adjustment thread, I7 housing, I8 cap screws for housing and anti-rotation device for I6, I9 housing of the machine to be driven, 2o holes in I7 for ventilation and readjustment of the brake.

Solange der Antriebsmotor abgeschaltet ist, drückt die Feder II die Bremsscheibe Io gegen den Außenkonus I6. Dieser ist durch Nuten und die Schrauben I8 in Drehrichtung festgehalten. Die angetriebene Maschine ist damit festgebremst. Sobald der Motor eingeschaltet wird, erhält die Hohlwelle 5 über antreibende Welle I und Paßfeder 3 ein Drehmoment. Dieses bewirkt, daß sich die Zähne 6 der Hohlwelle 5 relativ zu den Gegenzähnen 7 der Bremsscheibe Io etwas verdrehen. Durch diese Drehung wird die Bremsscheibe Io auf der Welle 2 infolge der schrägen Zahnflächen 6 und 7 axial verschoben, und zwar bis zum Anschlag gegen den Federteller I2. Dadurch löst sich die Konusbremse, und die anzutreibende Maschine kann jetzt vom Antriebsmotor angetrieben werden. Die Kraft wird dabei infolge des Anschlages der Bremsscheibe Io an den Federteller I2 über die Zahnkupplung 6, 7, die Nabe der Bremsscheibe Io und der Gleitfeder 4 übertragen. Sobald das antreibende Drehmoment fortfällt bzw. beim Ausschalten des Motors drückt die Feder II die Bremsscheibe Io wieder in die Verzahnung 6 bzw. 7 hinein, bis die Reibung zwischen Reibbelag I3 und Bremsscheibe Io die Welle 2 zum Stillstand gebracht hat.As long as the drive motor is switched off, the spring II presses the Brake disc Io against the outer cone I6. This is through the grooves and the screws I8 held in the direction of rotation. The driven machine is then braked. As soon as the motor is switched on, the hollow shaft 5 receives a driving shaft I and key 3 a torque. This causes the teeth 6 of the hollow shaft 5 slightly twist relative to the opposing teeth 7 of the brake disc Io. Through this Rotation is the brake disk Io on the shaft 2 due to the inclined tooth surfaces 6 and 7 shifted axially, up to the stop against the spring plate I2. Through this the cone brake is released and the machine to be driven can now use the drive motor are driven. The force is due to the impact of the brake disc Io to the spring plate I2 via the toothed coupling 6, 7, the hub of the brake disc Io and the slide spring 4 transmitted. As soon as the driving torque ceases or When the motor is switched off, the spring II pushes the brake disc Io back into the Toothing 6 or 7 in until the friction between the friction lining I3 and the brake disc Io brought wave 2 to a standstill.

Damit der Verschleiß des Bremsbelages ausgeglichen werden kann, ist der Außenkonus I6 der Bremse mit Gewinde in den Gehäusering I7 eingesetzt, jedoch an einer Drehung durch Nuten gehindert, in welchen die Schrauben I8 liegen. Zum Nachstellen der Bremse werden die Schrauben I8 etwas gelöst, so daß man den Gehäusering I7 drehen kann. Durch diese Drehung wird infolge des erwähnten Gewindes der Außenkonus I6 in Axialrichtung verschoben.So that the wear of the brake lining can be compensated the threaded outer cone I6 of the brake is inserted into the housing ring I7, however prevented from rotating by grooves in which the screws I8 lie. To the Adjusting the brake, the screws I8 are loosened a little, so that the housing ring I7 can rotate. As a result of this rotation, the outer cone is created as a result of the thread mentioned I6 shifted in the axial direction.
