Description

An eine elektrische -Maschine angebaute Riemenspannrolle Bekannt sind an elektrische Maschinen angebaute Riemenspannrollen, die um einen mit einer Feder versehenen Tragbolzen schwenkbar sind. Diese bekannten Riemenspannvorrichtungen sind den Anforderungen, die bei elektrischen Maschinen gestellt werden. insofern nicht ausreichend gewachsen, als hierbei die Kräfte unsymmetrisch verteilt sind, woraus sich ein verhältnismäßig großer Verschleiß der aufeinandergleitenden Flächen und unerwünschte zusätzliche Beanspruchungen in den die Spannrolle tragenden Teilen ergeben.Belt tensioning pulley attached to an electrical machine are known Belt tensioning pulleys attached to electrical machines, around one with a spring provided support bolts are pivotable. These known belt tensioning devices are the requirements that are placed on electrical machines. insofar not grown sufficiently when the forces are asymmetrically distributed, which results in a relatively large amount of wear and tear on the surfaces sliding on each other and undesirable additional stresses in the parts supporting the tension pulley result.

Gemäß der Erfindung werden diese Mängel dadurch vermieden, dali die Feder als Wendcwendel ausgebildet wird.According to the invention, these shortcomings are avoided by the dali Spring is designed as a helical coil.

Auf der Zeichnung ist ein Ausführungsbeispiel für die Erfindung in zwei verschiedenen Ansichten dargestellt.In the drawing, an embodiment of the invention is shown in shown in two different views.

i bedeutet den Lagerschild eines Elektromotors und -2 einen vorspringenden zylindrischen Teil desselben, an dem ein geschlitzter Tragrahmen 3 mittels einer Spannschraube 5 festgespannt ist. Der Tragrahmen 3 enthält ein Langloch 6, in dem das abgeflachte Ende eines Bolzens 8 sitzt, der mittels einer Mutter io an den Rahmen 3 befestigt ist. Auf dem Tragbolzen 8 sind die beiden Tragarme i i der Piemenspannrolle 4 schwenkbar gelagert. Auf den Tragbolzen 8 ist die Spannfeder 12 aufgewunden, welche aus zwei Teilen von entgegengesetztem Windungssinn besteht. Solche Federn werden als Wendewendeln bezeichnet. An dem gebogenen Übergangsstück zwischen den beiden hälften der Feder greift ein Stift 13 an, der in den Tragbolzen eingelassen ist. Die freien Enden 1,4 der Feder sind umgebogen und um die Tragarme i i herumgeschlungen. Hierzu i Blatt Zeichnungeni means the end shield of an electric motor and -2 a protruding one cylindrical part of the same on which a slotted support frame 3 by means of a Clamping screw 5 is tightened. The support frame 3 contains an elongated hole 6 in which the flattened end of a bolt 8 is seated, which is attached to the frame by means of a nut 3 is attached. On the support pin 8, the two support arms i i of the Piemenspannrolle are 4 pivoted. On the support bolt 8, the tension spring 12 is wound, which consists of two parts with opposite winding directions. Such feathers will be referred to as turning coils. At the curved transition piece between the two halves of the spring engages a pin 13 which is embedded in the support bolt. The free ends 1,4 of the spring are bent over and wrapped around the support arms i i. For this purpose i sheet of drawings
