Description

Die Erfindung betrifft einen Riemenspanner für den Anbau an elektrische Maschinen.The invention relates to a belt tensioner for attachment to electrical Machinery.

Es sind bereits Riemenspanner für den Anbau an elektrische Maschinen bekanntgeworden, die aus einer an einem Schwenkarm angeordneten Spannrolle bestehen, welche um einen mit einer Wendelfeder versehenen Tragbolzen schwenkbar ist. -Die bekannten Riemenspanner dieser Art haben den ?Nachteil, :daß das Nachspannen des Riemens nur innerhalb gewisser Grenzen möglich ist. Die Möglichkeit :des Nachspannens von Riemen wird gemäß der vorliegenden Erfindung dadurch wesentlich erweitert, daß man den Tragbolzen, auf dem die zum Spannen :dienende Feder sitzt, zur Achse der Motorriemenscheibe radial verschiebbar ausführt. Der Tragbolzen kann in einem Langloch eines an dem Maschinenlagerschild aufgehängten Tragrahmens der Spannvorrichtung unverdrehbar verschiebbar sein.There are already belt tensioners for attachment to electrical machines become known, which consist of a tensioning roller arranged on a swivel arm, which is pivotable about a support bolt provided with a helical spring. -The known belt tensioners of this type have the disadvantage: that the retensioning of the Belt is only possible within certain limits. The possibility: of re-tensioning of belts is substantially expanded according to the present invention in that the support bolt, on which the spring used for tensioning sits, becomes the axis of the Motor pulley executes radially displaceable. The support bolt can be in an elongated hole a support frame of the clamping device suspended from the machine end shield be non-rotatably displaceable.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.

Fig. i zeigt eine Draufsicht auf einen Riemenspanner und Fig. 2 eine Seitenansicht.FIG. I shows a plan view of a belt tensioner and FIG. 2 shows a Side view.

i bedeutet den Lagerschild des Motors, 2 einen vorspringenden zylindrischen Teil, an dem der geschlitzte Tragrahmen 3 für die Riemenspannrolle q. mittels der Spannschraube 5 festgespannt ist. Der Tragrahmen 3 weist ein Langloch 6 auf, in dem das abgeflachte Ende des Tragbolzens 8 zwischen einem Ansatz g und der ,Spannmutter i.o festgespannt ist. Auf dem Tragbolzen 8 sind die beiden Lagerarme I I der Riemenspannrolle q. schwenkbar befestigt. Auf dem Tragbolzen 8 ist :die Spannfeder (i2 aufgewunden, welche aus zwei Teilen mit entgegengesetztemWindungssinn besteht. An,dem schleifenförmigen Verbindungsstück der beiden Hälften der Feder greift dieses an dem Stift 13 an, der in den Tragbolzen eingelassen ist. Die freien Enden 1q. der Feder sind umgebogen und um die Tragarmei4 herumgeschlungen.i means the end shield of the motor, 2 a protruding cylindrical one Part on which the slotted support frame 3 for the belt idler q. by means of the Clamping screw 5 is tightened. The support frame 3 has an elongated hole 6 in which the flattened end of the support bolt 8 between a shoulder g and the, clamping nut OK is clamped. On the support pin 8 are the two bearing arms I I of the belt idler q. pivotally attached. On the support bolt 8 is: the tension spring (i2 wound, which consists of two parts with opposite windings. On, the loop-shaped one The connecting piece of the two halves of the spring engages the pin 13, which is embedded in the support bolt. The free ends 1q. the spring are bent over and wrapped around the support arm.
