KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft magnetelektrische Zündmaschinen mit Körperpol.The invention relates to body pole magneto-electric blasting machines.
Bei diesen Zündmaschinen fließt während jeder Kurzschlußperiode ein Teil des Stromes durch die Lagerfläche der Anker- und Verteilerwellen, auch wenn zwischen den drehbaren und feststehenden Stücken in üblicher Weise Schleifbürsten angeordnet sind, welche die Überleitung des Stromes bewirken sollen.In these ignition machines, part of the current flows during each short-circuit period through the bearing surface of the armature and distributor shafts, even if between the rotatable ones and fixed pieces are arranged in the usual manner grinding brushes, which to effect the transfer of the current.
ίο Der zerstörende Einfluß des Stromes auf die Lagerstellen ist daher bei dieser Einrichtung noch nicht vollständig beseitigt, was in Anbetracht der besonderen Betriebsverhältnisse bei Zündmaschinen als ein großer Nachteil angesehen werden muß.ίο The destructive influence of the current on the Bearing points is therefore not yet completely eliminated with this facility, which is in consideration the special operating conditions in blasting machines must be viewed as a major disadvantage.
Die Erfindung bezweckt, diesen Nachteil zu vermeiden und besteht im wesentlichen in der Anordnung einer die Achse oder deren Lagerstelle vom Apparatkörper trennenden Schicht aus isolierendem Material unter Beibehaltung der bekannten stromüberleitenden Schleifbürste an mindestens einem der Ankerlager des Zündapparates.The invention aims to avoid this disadvantage and consists essentially in the arrangement of a separating the axis or its bearing point from the apparatus body Layer of insulating material while maintaining the known current-carrying Abrasive brush on at least one of the armature bearings of the ignition apparatus.
Die Fig. ι und 2 zeigen Ausführungsformen der Erfindung, welche sich naturgemäß in mannigfacher Weise abändern und insbesondere auch auf Kugellager anwenden lassen. Als Beispiel ist in beiden Fällen das Lager auf der Antriebsseite eines Zündmaschinenankers dargestellt, und zwar ohne die stromvermittelnde Schleifbürste, da eine solche, wie schon erwähnt, nur an einem der Ankerlager erforderlich ist und hierfür in der Regel das auf der Rückseite des Apparates befindliche gewählt wird, die Bürste und ihre Ausführungseinzelheiten auch bekannt und nicht Gegenstand der Erfindung ist.Figs. Ι and 2 show embodiments of the invention, which naturally in Change in many ways and especially apply to ball bearings. as An example in both cases is the bearing on the drive side of a blasting machine armature shown, without the current-transmitting grinding brush, there such as already mentioned, is only required at one of the anchor bearings and this is usually the located on the back of the apparatus, the brush and its execution details also known and not the subject of the invention.
In Fig. ι bedeutet α den Lagerzapfen, b b eine Lagerbüchse, welche vermittels einer Isolierschicht c c vollständig vom übrigen Lagerkörper d getrennt ist. Für den Schmierdocht e sind in diesen Teilen entsprechende Aussparungen vorgesehen.In Fig. Ι α means the bearing pin, bb a bearing bush which is completely separated from the rest of the bearing body d by means of an insulating layer cc. For the lubricating wick e corresponding recesses are provided in these parts.
Fig. 2 stellt unter Beibehaltung der Bezugszeichen den Fall dar, daß nicht die Lager- stelle vom Körper, sondern die Achse von der Lagerstelle isoliert ist. Zu diesem Zwecke ist auf die Achse α ein Laufring bl b1 unter Zwischenlagerung einer Isolierschicht c1 c1 fest aufgezogen, welche mit der Achse umläuft und dessen Außenseite die Lauffläche bildet.Fig. 2, while retaining the reference numerals, shows the case in which it is not the bearing point that is isolated from the body, but rather the axis is isolated from the bearing point. For this purpose, a running ring b l b 1 is firmly drawn onto the axis α with an interposed insulating layer c 1 c 1 , which rotates with the axis and the outside of which forms the running surface.
