Abstract

Thread brake with radial magnets (1) on a carrier disc which has a set of radial grooves forming ribs which act as a cooling member, has a central ring of ventilating holes at the ends of the ribs as in the main patent. The braking disc adjacent to the carrier has a further set of holes on the same pitch circle as the other holes, allowing cooling air to pass through. The braking disc has a sleeve through which passes a torsion rod with its outer end fixed in the base frame, with sufficient resilience to enable the torsion to be indicated on a scale on the edge of the braking disc.

Description

Fadenbremse Thread brake

1. Zusatzanmeldung Zweck der Erfindung ist die Leistung bekannter Fadenbremsen dadurch zu erhöhen, daß ein neues Kühlsystem angewendet wird. 1. Additional registration The purpose of the invention is the achievement of well-known Increase yarn brakes by using a new cooling system.

Bekannte Fadenbremsen haben an den äußeren Gehäuseteilen Kühlrippen oder integrierte Lüfterräder, die zum Teil Kühlluft durch den Luftspalt zwischen dem Magnet und der Bremsscheibe saugen.Known thread brakes have cooling fins on the outer housing parts or integrated fan wheels, some of the cooling air through the air gap between the magnet and the brake disc.

In der Patentanmeldung P 29 29 183.6 ist eine Kühleinrichtung für die Magnete im Nebenschluß beschrieben (21 + 22), bei welcher der Hauptstrom vom umlaufenden Gehäuse erzeugt wird.In the patent application P 29 29 183.6 is a cooling device for the magnets in the shunt described (21 + 22), in which the main current from surrounding housing is generated.

Vorliegende Erfindung erhöht die Kühlleistung erheblich dadurch, daß radial angeordnete Stabmagnete 1 von bestimmter Dicke oder dünnere Magnete 2 auf erhöhte Sockel 3 so befestigt werden, daß sie mit einem genügenden Abstand zueinander Kanäle 4 bilden, die die Eigenschaft von Verdichterschaufeln haben und die erforderlichen Kühlluftmengen, bei Rotation, durch Öffnungen 5 in Achsnähe direkt zwischen dem Magnetträger (6) und der Bremsscheibe (7) absaugen. Der Luftdurchsatz ist durch diese Konstruktion erheblich verbessert, so daß die Bremse entsprechend höher zu belasten ist.The present invention increases the cooling performance significantly in that radially arranged bar magnets 1 of a certain thickness or thinner magnets 2 increased base 3 are attached so that they are at a sufficient distance from each other Form channels 4, which have the property of compressor blades and the required Cooling air quantities, during rotation, through openings 5 near the axis directly between the Vacuum the magnet carrier (6) and the brake disc (7). The air flow is through this design is significantly improved, so that the brake is correspondingly higher burden is.

Um das Drehmoment gleichzeitig ablesen zu können, ist eine verbesserte Einrichtung vorhandene die aus einem Torsionsstab (8) besteht, welcher von der Brernischeibe 7 verdreht wird und sich platzsparend in die Achsmitte einbauen läßt. Der auf der Skala 9 in bekannter Weise angezeigte Drehwinkel ist ein Maß für die Bremsleistung beispielsweise einer Fadenzugkraft. 10 und 10 sind Wellenzapfen, 11 und 11' die dazugehörigen Lager. 12 soll ein Gehäuseteil bedeuten, 13 ist der Kühlluftweg.In order to be able to read the torque at the same time, an improved Device existing consisting of a torsion bar (8), which is from the Brerni disk 7 is rotated and can be installed in the center of the axle to save space. The one on the Scale 9 indicated rotation angle in a known manner is a measure of the braking power for example a thread tension. 10 and 10 are shaft journals, 11 and 11 'are the associated warehouse. 12 should mean a housing part, 13 is the cooling air path.
