Description

Die Erfindung bezieht sich auf einen Stromwender mit Kohlelanzellen, bei welchem zur Stromzu- oder -abführung an ,die oder von den Kohlelamellen Metallbeilagen verwendet werden.The invention relates to a commutator with coal cells, in which to supply or discharge electricity to, or from the carbon lamellas, metal shims be used.

Die Erfindung besteht darin, daß an den Metallbeilagen die Kohlelarnellen mit .dein Fuß und den Flanken mittelsVertiefungen oder .durchBohrungen in axialer Richtung angebracht sind, die Metallbeilagen und .die Kohlelamellen mit dem Tragkörper verankert sind, die Metallbeilagen in axialer Rich.-tung über die Kohlelamellen hinaus in den Spannteller hineinragen, in radialer Richtung über die Kohlelamellen ein- oder beidseitig hinausragen und diese Fortsätze als Fahnen ausgebildet sind und als Ventilator dienen.The invention consists in the fact that on the metal shims the charcoal shrimp with .your foot and the flanks by means of indentations or .by bores in axial Direction are attached, the metal shims and .die carbon lamellas with the support body The metal shims are anchored in the axial direction over the carbon lamellas protrude into the clamping plate, in the radial direction over the carbon lamellas protrude on one or both sides and these extensions are designed as flags and serve as a fan.

Gegenüber dem Bekannten zeichnet sich die Erfindung durch folgende Vorteile aus: Der Träger und die beiden Spannteller des Stromwenders bilden zusammen mit den in- axialer Richtung verlaufenden und in den Tellern verankerten Metallbeilagen ein festes Gerippe, in weichem die Kohle.-lamellen, die mit den, Metallbeilagen .durch Nieten oder Löten verbunden sind, festsitzen. Damit sind ,die Metallbeilagen im Gegensatz zu den bekannten Anordnungen eine Stütze für die Kohlelamellen.Compared to the known, the invention is characterized by the following Advantages from: The carrier and the two clamping plates of the commutator form together with the metal shims that run in the axial direction and anchored in the plates a solid framework, in which the coal lamellas with the metal attachments . connected by riveting or soldering, sit tight. With that, the metal inserts In contrast to the known arrangements, a support for the carbon lamellas.

Biegungsbeanspruchungen, gegen welche die Kohle besonders empfindlich ist, werden von den Metallbeilagen aufgenommen, an welchen die Kohlelamellen befestigt sind. Dadurch; daß in axialer Richtung dieMetallbeilagen über die Kohlelamellen hinaus in den Spannteller hineinragen, ist die Wärmeabfuhr aus dem Innern des Stromwenders besonders gut. Durch die Ausbildung der Metallbeilagen als Fortsätze in radialer Richtung, welche gleichzeitig als Ventilator dienen, wird die Kühlluft günstig über die Stroinwenderoberfläche und durch die Maschine geleitet.Bending loads to which the carbon is particularly sensitive are picked up by the metal shims to which the carbon slats are attached are. Through this; that in the axial direction the metal shims over the carbon lamellas protrude into the clamping plate, is the heat dissipation from the inside of the commutator especially good. By forming the metal shims as extensions in a radial direction Direction, which also serve as a fan, the cooling air is cheap over the strobe user interface and passed through the machine.

An Hand der Zeichnung wird die Erfindung weiter erläutert. Es ist Fig. i ein axialer Schnitt, Fig. 2 ein Schnitt nach Fig. i nach der Linie I-I. In dem Tragkörper i sind die Kohlelamellen 4. zusammen mit den tIVIetallbeila:gen fest verankert, indem an den Metallbeilagen .6 die Kohlelamellen 4 mit dem Fuß und den Flanken mittels Vertliefungen oder durch Bohrungen in axialer Richtung angebracht sind. Der Tragkörper li und die beiden Spannteller 2 des Stromwenders bilden zusammen mit den in axialer Richtung verlaufenden und. in .den Tellern 2 verankerten Metallbeilagen 6 ein festes Gerippe, in welchem die Kohlelamellen festsitzen. Axial ragen die Metallbeilagen 6 mit den Fortsätzen 5a über die Kohlelamellen 4 hinaus in den Spannteller :2 hinein. 5 sind die radial nach außen geführten Fahnen der ;Metallbeilagen ,6 zum Anlöten der Wicklung. Sie bilden gleichzeitig einen Ventilator. Mit 3 ist die Jsolation zwischen Spanntellere, Kohlelamelle 4 und Metallbeilage 6 bezeichnet. Die Isolierlamelle 7 trennt die Kohlelamelle 4 elektrisch von der benachbarten.The invention is further explained with reference to the drawing. It is Fig. I is an axial section, Fig. 2 is a section according to Fig. I along the line I-I. In The carbon lamellas 4. together with the metal shims are fixed to the supporting body i anchored by attaching the carbon lamellas 4 to the metal shims .6 with the foot and the Flanks attached in the axial direction by means of recesses or holes are. The support body li and the two clamping plates 2 of the commutator form together with the axially extending and. in .the plates 2 anchored metal shims 6 a solid frame in which the coal lamellas are stuck. The metal shims protrude axially 6 with the extensions 5a beyond the carbon lamellas 4 into the clamping plate: 2 into it. 5 are the radially outwardly directed flags of the; metal shims, 6 for soldering the winding. They also form a fan. With 3 there is isolation between clamping plate, carbon lamella 4 and metal shim 6 designated. The insulating lamella 7 electrically separates the carbon lamella 4 from the neighboring one.
