Description
Gegenstand der Erfindung ist ein mit einer Reibungskupplung zusammengebauter Elektromotor. Die Kupplungswelle ist in einer längs verschiebbaren Buchse drehbar gelagert und trägt an ihrem dem Motor zugekehrten Ende das angetriebene Kupplungsglied und auf dem anderen Wellenende eine' Riemenscheibe. The invention relates to an electric motor assembled with a friction clutch. The coupling shaft is rotatably mounted in a longitudinally displaceable bush and carries the driven coupling member and at its end facing the motor a pulley on the other end of the shaft.
Die Einleitung des Kupphmgs- oder Brems-Vorganges erfolgt bei diesen bekannten Motoren durch eine Drehbewegung und Längsverschiebung der Buchse entgegen einer Federkraft mittels eines mit der Buchse starr verbundenen Bolzens, der von einer Rolle umgeben ist und seine Führung durch eine schraubenförmig gewundene Nut in der Nabe des Gehäuses erhält.The initiation of the Kupphmgs- or braking process takes place in these known motors by a rotary movement and longitudinal displacement the bushing against a spring force by means of a bolt rigidly connected to the bushing, which comes from a roller is surrounded and its leadership by a helically wound groove in the hub of the housing.
Es hat sich bei Ausführungen dieser Art in der Praxis herausgestellt, daß solche als kon-It has been found in practice with designs of this type that such as con-
ao zentrisch zur Welle liegende Zugfedern ausgebildete Federn, besonders an den Einspannstellen, Überbeanspruchungen unterworfen sind, was nicht selten zum Bruch der Aufhängeösen führt; außerdem verschmutzen dieao formed tension springs lying centrically to the shaft Springs, especially at the clamping points, are subject to overstressing, which often leads to breakage of the suspension eyes leads; also pollute the
Steuerorgane der Kupplung sehr leicht, wo- 25 durch die Betriebssicherheit beeinträchtigt .wird.Control members of the clutch are very light, which impairs operational safety .will.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden.The present invention is based on the object of avoiding these disadvantages.
Erfindungsgemäß ist konzentrisch zur Kupplungswelle und zur Gehäusenabe am äußeren Umfang der Nabe -eine der Einstellbewegung entgegenwirkende schraubenförmig gewundene Drehungsfeder angeordnet, deren Kapselung durch eine entsprechend der Steigung eines Schraubenganges bewegbare, die Lager der Kupplungswelle aufnehmende Buchse, eine mit der Buchse fest verbundene Hülse sowie den der Feder zugewandten Teil des kupplungsseitigen Gehäuses gebildet wird.According to the invention is concentric to the coupling shaft and to the housing hub on the outside Circumference of the hub - a helically wound counteracting the adjustment movement Torsion spring arranged, the encapsulation by a movable according to the pitch of a helical thread, the bearings the coupling shaft receiving socket, a sleeve firmly connected to the socket and the part of the clutch-side housing facing the spring is formed.
Gegenüber bekannten Ausführungen mit zwischen Motorläufer und Riemenscheibe eingebauter Reibungskupplung, die mittels eines Einstellhebels entgegen einer Federkraft durch Schraubengangf ührung einer Lagerbuchse axial aus der Brems- in die Kupplungsstellung verschoben wird, unterscheidet sich der Gegenstand der Erfindung in der Hauptsache da-Compared to known designs with built-in between the motor rotor and belt pulley Friction clutch, which by means of an adjusting lever against a spring force Screw thread guide of a bearing bush shifted axially from the braking position into the coupling position the subject matter of the invention differs in the main
