Claims (6)

1. Einrichtung zur Erfassung des Lagerspieles und oder der Durchbiegung von An­ triebswellen insbes. von Elektromotoren mit einem auf das Motorgehäuse aufge­ setztem Lagerschild oder dgl. das die Antriebswelle umschliesst und das Lager ab­ deckt, dadurch gekennzeichnet, dass am Lagerschild (4) oder an einer ent­ prechenden Lagerabdeckung, im Bereich des Wellenumschlusses mit geringem Abstand, ein elektrisch leitender Kontaktring (5) isoliert angeordnet ist, der bei Berührung mit der Antriebswelle (1) einen dem Motor, insbes. der Antriebswelle (1) zugeordneten Signalstromkreis schliesst.1. Device for detecting the bearing play and or the deflection of drive shafts, in particular of electric motors with a bearing plate placed on the motor housing or the like, which encloses the drive shaft and covers the bearing, characterized in that on the bearing plate ( 4 ) or on A corresponding bearing cover, in the area of the shaft enclosure at a short distance, an electrically conductive contact ring ( 5 ) is arranged insulated, which closes a signal circuit associated with the motor, in particular the drive shaft ( 1 ) when it comes into contact with the drive shaft ( 1 ). 2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass der Kontaktring (5) gegenüber dem Wellenumschluss des Lagerschildes (4) derart vorsteht, dass der Spalt zwischen Kontaktring (5) und Welle (1) nur geringfügig grösser ist, als das zulässige Lagerspiel plus der betriebsbedingten Durchbiegung der Antriebswelle (1) im Bereich des Lagerschildes (4), bzw. dem betriebsbedingten Spalt zwischen Rotor und Stator des Motors.2. Device according to claim 1, characterized in that the contact ring ( 5 ) protrudes relative to the shaft encirclement of the bearing plate ( 4 ) such that the gap between the contact ring ( 5 ) and shaft ( 1 ) is only slightly larger than the permissible bearing play plus the operational deflection of the drive shaft ( 1 ) in the area of the end shield ( 4 ), or the operational gap between the rotor and stator of the motor. 3. Einrichtung nach Anspruch 1 und 2, dadurch gekennzeichnet, dass der Kontaktring (5) zumindest auf der der Welle (1) zugekehrten Fläche mit einer abreibbaren Isolierschicht z. B. aus Isolierlack versehen ist.3. Device according to claim 1 and 2, characterized in that the contact ring ( 5 ) at least on the shaft ( 1 ) facing surface with an abradable insulating layer z. B. is made of insulating varnish. 4. Einrichtung nach Anspruch 1 bis 3, dadurch gekennzeichnet, dass der Kontakt­ ring (5) auf der Innenseite des Lagerdeckels (4) vorzugsweise in einer Ringnut angeordnet ist.4. Device according to claim 1 to 3, characterized in that the contact ring ( 5 ) on the inside of the bearing cover ( 4 ) is preferably arranged in an annular groove. 5. Einrichtung nach Anspruch 1 bis 4, dadurch gekennzeichnet, dass der Kontakt­ ring (5) in die dem Gehäuseteil (10) zugehörige Wellendichtung (9) elektrisch isoliert eingelassen ist.5. Device according to claim 1 to 4, characterized in that the contact ring ( 5 ) in the housing part ( 10 ) associated shaft seal ( 9 ) is embedded electrically isolated. 6. Einrichtung nach Anspruch 1 bis 5, dadurch gekennzeichnet, dass der Signal­ stromkreis derart niederohmig ausgelegt ist, dass nur direkte, niederohmige Kontakte den Signalstromkreis schliessen.6. Device according to claim 1 to 5, characterized in that the signal circuit is designed so low-resistance that only direct, low-resistance contacts close the signal circuit.
