Description
Stromabnehmerrolle für elektrische Bahnen. Bei elektrischen Straßen- und Eisenbahnen, denen der Strom durch einen Leitungsdraht zugeführt wird, erfolgt die Stromabnahme vielfach durch eine auf der Stromabnahmestange drehbar angeordnete Laufrolle.Collector reel for electric railways. In the case of electric road and railways to which electricity is supplied by a conductor wire the current pick-up often by a rotatably arranged on the current pick-up rod Caster.
Die Erfindung bezweckt,' die bei der Arbeit der gegeneinanderreibenden Teile der Stromabnehmerrolle entstehende Abnutzung selbsttätig auszugleichen und dabei doch eine vollständige Stromabnahme zu sichern.The invention aims' at the work of the rubbing against each other Automatically compensate for wear and tear on parts of the pantograph roller to ensure a complete supply of electricity.
Um dieses Ziel zu erreichen, wird die Stromabnehmerrolle nicht unmittelbar auf ihre von der Stromabnehmerstange getragene Achse drehbar aufgesetzt, sondern auf zwei abgestumpft kegelförmig gestaltete, auf dieser Achse in der Längsrichtung verschiebbare Lager aufgesteckt, die durch eine sie umgebende Feder in Bewegung gesetzt werden. Diese beiden Lager sitzen auf der. Achse der Rolle in umgekehrter Richtung hinsichtlich ihrer konischen Schleifflächen, die durch die zwischengelegte Feder gegen die Wandungen der Aushöhlung angepreßt werden. Durch die Berührungsflächen zwischen den konischen Köpfen der beiden Lager und der sich auf diesen drehenden Rolle, gegen welche diese Köpfe beständig durch die Feder angepreßt werden, .entsteht eine Abschleifung der Reibflächen, die durch das selbsttätige Nachrücken der Lagerhülsen ausgeglichen wird. Die Zeichnung stellt ein Ausführungsbeispiel einer solchen Stromabnahmevorrichtung dar.To achieve this goal, the pantograph role is not immediate rotatably mounted on their axis carried by the current collector rod, but on two truncated cone-shaped, on this axis in the longitudinal direction Slidable bearings attached, which are set in motion by a spring surrounding them be set. These two camps sit on the. Axis of the roll in reverse Direction in terms of their conical grinding surfaces, which are interposed by the Spring are pressed against the walls of the cavity. Through the contact surfaces between the conical heads of the two bearings and the one rotating on them Role against which these heads are constantly pressed by the spring a grinding of the friction surfaces caused by the automatic moving up of the bearing sleeves is balanced. The drawing shows an embodiment of such a current collection device represent.
Auf der Achse a der Stromabnehmerstange oder einer beliebigen Tragvorrichtung sind zwei Hülsen b mit abgestumpft kegelförmigen Köpfen, die in entgegengesetzter Richtung stehen, aufgesteckt. Diese Hülsen sind-gegen Drehung auf der Achse a durch einen aus letzterer vorstehenden, in einen Ausschnitt c eingreifenden Stift d gesichert. Eine um die Hülsen b gelegte Schraubenfeder e drückt die beiden Hülsen b beständig nach außen gegen die abgeschrägten Innenwandungen der Aushöhlung der Rolle f an.On the axis a of the pantograph rod or any supporting device are two sleeves b with truncated conical heads that are in opposite Direction stand, plugged in. These sleeves are against rotation on the axis a through secured a pin d protruding from the latter and engaging in a cutout c. A helical spring e placed around the sleeves b presses the two sleeves b constantly outwards against the beveled inner walls of the cavity of the roller f.
Die Rolle f wird sich, wie gewöhnlich, durch die Reibung des in ihrer Auskehlung liegenden Zuleitungsdrahtes und die Fortbewegung des Fahrzeuges drehen und folglich auf den auf ihrer Achse a gegen Drehung festgehaltenen Hülsen b schleifen; diese Schleifwirkung findet jedoch nur gegen die konischen Aussenflächen der Lagerhülsen statt. Jede Abnutzung wird durch den Druck der Feder c ausgeglichen, welche beide Hülsen b in entgegengesetzter Richtung zu verschieben strebt. Die Rolle f bleibt beständig in gleicher, zentrierter Lage auf ihrer Achse a, um welche sie sich dreht.The roller f will, as usual, be affected by the friction of its Turn the lead wire lying in the groove and move the vehicle and consequently grind on the sleeves b held against rotation on their axis a; however, this grinding effect only takes place against the conical outer surfaces of the bearing sleeves instead of. Any wear and tear is offset by the pressure of the spring c, both of which Tends to move sleeves b in the opposite direction. The role f remains constantly in the same, centered position on its axis a, around which it rotates.
Diese selbsttätige Nachstellung der Reibungsflächen, die sich durch die Feder c vollzieht, erspart auch jedes Schmiermittel und gestattet einen ununterbrochenen Kontakt für die Über- leitung des elektrischen Stromes.This automatic adjustment of the friction surfaces, which is accomplished by the spring c, also saves any lubricant and allows uninterrupted contact for the over- line of electric current.
