Description

Anlagezur Gebrauchsmuster-Anmeldung abyrinthartige Lagerdjchtun für eleltrische Kleinmasehinen Die Neuerung bezieht sich auf eine labyrinthartige Lagerdichtung für elektrische Kleinmaschinen die einen auf der Ankerwelle sitzenden, von einem Isolierpreßstoffkörper gehaltenen Stromabnehmer (Kollektor oder Schleifring) haben und deren Welle mindestens auf der Stromabnehmerseite in einem Kalottenlager läuft, dessen. Kalotte zwischen dem Lagerdeckel der Maschine und einer an-diesem befestigten Scheibe eingespannt isto Durch die Neuerung wird eine wesentliche Verbilligung der Maschiene dadurch herbeigeführtf daas die Scheibe mit einem halsartigen Ansatz in eine auf der Stromseite des Isolierpreßstoffkörpers vorgesehene Kreisrille hineinragt. To the Utility model registration abyrinth-like camp dychtun for electronic Kleinmasehinen The innovation relates to a labyrinth-like bearing seal for small electrical machines that have a current collector (collector or slip ring) sitting on the armature shaft and held by a molded insulating body and whose shaft runs at least on the current collector side in a spherical bearing. The spherical cap is clamped between the bearing cover of the machine and a disk attached to it. The innovation makes the machine much cheaper because the disk protrudes with a neck-like extension into a circular groove on the stream side of the molded insulating material.

Die Zeichnung zeigt als Ausführungsbeispiel des Gegenstandes der Neuerung einen kleinen Elektromotor teilweise im Schnitte Mit 10 ist das Gehäuse, mit 11 der Anker und mit 12 der Kollektor des Elektromotors bezeichnet. Die Lamellen 13 des Kollektors werden durch einen Ring 14 aus Isolierpreßstoff zusammengehaltene Anker und Kollektor sitzen auf einer Uelle 159 die in Kalottenlagern 16 gelagert isto Die auf der Kollektorseite befindliche Kalotte 17 ist zwischen einem aus Blech geprägten Lagerschild 18 und einer auf dessen Innenseite befestigten gewellten Blechscheibe 19 eingespannt. Diese hat einen halsartigen Ansatz 20t der in eine an der Stirnseite des Ringes 14 angebrachte Rille-21 hineinragt. Die durch den Ansatz 20 und die Rille 21 gebildete labyrinthartige Dichtung verhinderte dass Schmierstoff, der aus dem Lager heraus entlang der Welle wandert auf den Kollektor gelangen kann.The drawing shows an embodiment of the subject of innovation a small electric motor partly in section At 10 that is Housing, with 11 the armature and 12 with the collector of the electric motor. The lamellae 13 of the collector are held together by a ring 14 made of molded insulating material The armature and collector sit on a Uelle 159 which is mounted in spherical bearings 16 isto The dome 17 on the collector side is between a sheet metal embossed end shield 18 and a corrugated sheet metal disk attached to the inside thereof 19 clamped. This has a neck-like extension 20t in one on the front side of the ring 14 attached groove-21 protrudes. The through the approach 20 and the groove The labyrinth-like seal formed in 21 prevented lubricant from escaping from the Bearing migrating out along the shaft can get onto the collector.
