Belüftungseimichtung für in einem Gehäuse angeordnete Schleifringe elektrischer
Maschinen.
Zum Zusammenarbeiten mit Schleifringen elektrischer Maschinen verwendet man vielfach Kohleoder Kupfer-Kohle-Bürsten. Bei längerem Gebrauch derselben zeigt sich dabei der Übelstand, dass der von den Bürsten sieh abschleifende feine Staub sich auf anderen Teilen der Maschine ferner auf allen Instrumenten und Apparaten und schliesslich im ganzen Maschinenraum selbst niederschlägt. Da dieser

die gute Isolation der Maschinen und Apparate zu gefährden. Seine Ablagerung ist daher unerwünscht, zumal der Staub auch gesundheitsschädlich ist.
Die Erfindung bezweckt, dem geschilderten Übelstand abzuhelfen, u. zw. wird dieser Zweck gemäss der Erfindung dadurch erreicht, dass seitlich der Schleifringe ein Ventilator angeordnet ist, durch den

ringe und die Bürsten in an sich bekannter Weise von einem Gehäuse umschlossen, während die gemeinsame Nabe der Schleifringe als Hohlkörper ausgebildet und an ihrem Umfang mit seitlich von den Schleifringen liegenden Öffnungen versehen wird, durch welche die auf der einen Stirnseite der Nabe eingesaugte Kühlluft in radialer Richtung in den von dem Gehäuse umschlossenen Raum eintreten kann, von wo sie durch den am Ende des Gehäuses angeordneten Lüfter abgesaugt wird.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes teilweise im Schnitt und

Mengen Kupfer zugesetzt sind. Hierin liegt ein nicht unwesentlicher Nebenvorteil des Erfindunggegenstandes.
Man kann natürlich, wenn man auf die Rückgewinnung des Bürstenstaubes verzichtet, das Filter auch weglassen und den Staub einfach ins Freie leiten.
Durch den das Schleifringgehäuse 6 durchziehenden Luftstrom wird nicht nur der Bürstenstaub abgesaugt, sondern zugleich eine sehr wirksame Kühlung der Schleifringe selbst erzielt.

Ventilation device for electrical slip rings arranged in a housing
Machinery.
Carbon or copper-carbon brushes are often used to work with slip rings of electrical machines. If they are used for a long time, the disadvantage is that the fine dust that is abraded by the brushes is deposited on other parts of the machine, on all instruments and apparatus, and finally in the whole machine room itself. Since this

endangering the good insulation of the machines and devices. Its deposition is therefore undesirable, especially since the dust is also harmful to health.
The invention aims to remedy the drawback described, u. between. This purpose is achieved according to the invention in that a fan is arranged to the side of the slip rings through which

rings and the brushes are enclosed in a known manner by a housing, while the common hub of the slip rings is designed as a hollow body and is provided on its circumference with openings to the side of the slip rings through which the cooling air sucked in on one end face of the hub is radially Direction can enter into the space enclosed by the housing, from where it is sucked off by the fan arranged at the end of the housing.
In the drawing, an embodiment of the subject invention is partially in section and
EMI1.3
<Desc / Clms Page number 2>
Amounts of copper are added. This is a not insignificant secondary advantage of the subject matter of the invention.
Of course, if you dispense with the recovery of the brush dust, you can also omit the filter and simply direct the dust outside.
Due to the air flow passing through the slip ring housing 6, not only is the brush dust sucked off, but at the same time very effective cooling of the slip rings themselves is achieved.
