Bei Kommutatormaschine!! macht sich das durch Vibration der Bürsten verursachte Geräusch häufig· in störender Weise bemerkbar. Dies ist besonders der Fall bei Bahnmotoren, die mit wechselnder Geschwindigkeit und in beiden Drehrichtungen laufen.
. Gemäß der Erfindung· wer den diese Bürstengeräusche dadurch vermieden, daß die Bürsten gegen den Radius des Kollektors um einen Winkel geneigt angeordnet werden, der größer als der Reibungswinkel ist. Hierbei können die Bürsten in der Weise geneigt sein, daß die Richtungen der Bürstenachsen zu der Richtung der Maschinenachse senkrecht stehen, wie dies in Abb. 1 der Zeichnung dargestellt ist, oder noch besser zur Richtung dieser Achse geneigt sind entsprechend Abb. 2. Bei dieser Anordnung sind also die Bürsten auch etwas seitwärts geneigt, so daß die Bürstenkanten einen Winkel mit den Lamellen des Kommutators einschließen.
With commutator machine !! the noise caused by the vibration of the brushes is often noticeable in a disturbing way. This is particularly the case with rail motors that run at changing speeds and in both directions of rotation.
. According to the invention, these brush noises are avoided in that the brushes are inclined relative to the radius of the collector at an angle which is greater than the angle of friction. The brushes can be inclined in such a way that the directions of the brush axes are perpendicular to the direction of the machine axis, as shown in Fig. 1 of the drawing, or even better are inclined to the direction of this axis as shown in Fig. 2. In this case Arrangement so the brushes are inclined slightly to the side so that the brush edges form an angle with the lamellae of the commutator.

Eine Neigung der Bürstenkante gegen die Kommutatorlamellen kann auch durch die aus Abb. 3 ersichtliche Anordnung erreicht wer-An inclination of the brush edge against the commutator bars can also be caused by the Fig. 3 visible arrangement can be achieved

Mit besonderem Vorteil können bei Maschinen mit mehr als zwei in der Umfangsrichtung aufeinanderfolgenden Bürsten die in der Umfangsrichtung aufeinanderfolgenden Bürsten in bezug aufeinander entgegengesetzt geneigt zur Schleiffläche angeordnet werden, wie dies in Abb. 4 gezeigt ist. Hierbei wird zweckmäßig der Winkel zwischen den Bürstenkanten der aufeinanderfolgenden Bürsten und den Lamellen gleichgehalten.It is particularly advantageous for machines with more than two in the circumferential direction consecutive brushes the brushes which follow one another in the circumferential direction are opposite in relation to one another be inclined to the grinding surface, as shown in Fig. 4. Here is expediently the angle between the brush edges of the successive brushes and kept the same as the slats.

Die Schrägstellung der Bürsten in der Weise, daß ihre Richtung auf der Maschinenachse senkrecht steht, ist an sich bekannt und wird z. B. bei den sogenannten Reaktionshaltern verwendet, um unter Zusammenwirken der auf die Bürste einerseits vom Kommutator, (andererseits von der Alipreßeinrichtung ausgeübten Kräfte eine möglichst reibungslose Führung der Bürste in dem Halter zu erreichen und so die Kommutierungsverhältnisse zu verbessern. Diese Anordnung hat jedoch bisher ausschließlich bei nur für eine Drehrichtung bestimmten Maschinen Anwendung gefunden, da ja nur bei diesen das gewünschte Zusammenwirken der genannten Kräfte ^eintreten kann. Für Maschinen mit wechselnder Drehrichtung sind jedoch bisher ausschließlich in streng radialer Richtung angeordnete Bürsten verwendet worden.The inclination of the brushes in such a way that their direction on the machine axis stands vertically, is known per se and is z. B. used in the so-called reaction holders to work together the one on the brush from the commutator on the one hand, (on the other hand from the aluminum pressing device forces exerted to guide the brush in the holder as smoothly as possible achieve and thus improve the commutation ratios. However, this arrangement has previously only used in machines designed for only one direction of rotation found, since it is only with these that the desired interaction of the forces mentioned can occur. For machines with alternating directions of rotation have so far only been arranged in a strictly radial direction Brushes have been used.

Infolge der Neigung werden die Erschütterungen der Bürsten beim Laufen der Maschine vermieden, wobei etwa eine ähnliche Erscheinung auftritt wie bei dem Gleiten, einer KreideAs a result of the inclination, the brushes shake when the machine is running avoided, whereby a similar phenomenon occurs as with the sliding of a chalk

Bei Maschinen, die gemäß der Erfindung ausgeführt sind, sind demnach die Bürstengeräusche völlig vermieden und infolge des ruhigen Anliegens der Bürsten auch die Kommutierungsverhältnisse wesentlich verbessert. Außerdem wird die Lebensdauer der Kohle erheblich verlängert, da keine nennenswerten Erschütterungen der Bürsten auftreten und diese daher auch nicht abbröckeln können.In machines designed according to the invention, the brush noises are accordingly completely avoided and, as a result of the smooth contact of the brushes, also the commutation conditions much improved. In addition, the life of the coal is considerably extended, since there are no significant ones Vibrations of the brushes occur and they cannot crumble off.

Von besonderer Bedeutung ist die Erfindung bei Bahnmotoren, bei denen einerseits eine Verlängerung der Lebensdauer der Bürsten besonders wünschenswert ist, andererseits die Bürstengeräusche, deren restlose BeseitigungThe invention is of particular importance in rail engines, in which on the one hand a Extending the life of the brushes is particularly desirable, on the other hand Brush noises, their complete elimination

ao bisher nicht immer möglich gewesen ist, sich aber häufig sehr störend bemerkbar machen.ao has not always been possible so far, but is often very annoying.
