Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Übertragungselement, insbesondere eine Riemenscheibe oder Rolle für einen Zugmitteltrieb, mit einem Mittel zum Abführen elektrostatischer Ladungen.The The invention relates to a transmission element, in particular a pulley or pulley for a traction drive, with a means for removing electrostatic charges.
Hintergrund der ErfindungBackground of the invention
Bei Zugmitteltrieben, bei denen ein Umschlingungsmittel wie ein Riemen um Übertragungselemente wie Riemenscheiben oder Rollen geschlungen ist, werden durch die unterschiedlichen Relativgeschwindigkeiten elektrostatische Ladungen freigesetzt, die dazu führen, dass sich einzelne Komponenten des Riementriebs, insbesondere Riemenscheiben oder Rollen, statisch aufladen. Dieses Problem wird heutzutage dadurch verschärft, dass Übertragungselemente wie Riemenscheiben oder Rollen üblicherweise aus Kunststoffmaterialien hergestellt sind, die als Isolator für die Ladungen dienen und eine Ablei tung der Ladungen verhindern. Durch die Ansammlung der Ladungen steigt die Spannung zwischen dem Übertragungselement und dem Massepotential soweit an, bis es zu einer spontanen Entladung in der Form eines Funkenüberschlags kommt. Ein derartiger Funkenüberschlag kann beispielsweise im Bereich eines Wälzlagers auftreten, wobei der Überschlag zwischen der Rolle oder Riemenscheibe oder dem Außenring des Wälzlagers und dem Innenring des Wälzlagers, das mit einem Massepotential verbunden ist, auftritt. Dabei besteht die Gefahr, dass derartige Funkenüberschläge das Wälzlager schädigen, daneben kann auch ein in dem Wälzlager enthaltener Schmierstoff zumindest langfristig geschädigt werden. Funkenüberschläge wirken sich auch nachteilig auf elektronische Bauteile aus, die an oder im Umfeld einer Brennkraftmaschine angeordnet sind.at Traction drives, in which a belt like a belt around transmission elements such as pulleys or rollers are looped through the different relative speeds released electrostatic charges that cause that individual components of the belt drive, in particular pulleys or rolls, static charge. This problem is nowadays by this aggravates that transmission elements such as pulleys or rolls are usually made of plastic materials, which serve as an insulator for the charges and a Ablei direction prevent the charges. By the accumulation of the charges rises the voltage between the transmission element and the ground potential so far, until there is a spontaneous discharge in the form of a Sparking comes. Such a flashover can occur, for example, in the area of a rolling bearing, the rollover between the roller or pulley or the outer ring of the rolling bearing and the inner ring of the rolling bearing, which is connected to a ground potential is, occurs. There is a risk that such arcing damage the rolling bearing, next to it can also in the rolling bearing contained lubricant at least long term be damaged. Flashovers also have a detrimental effect on electronic components that are arranged on or in the environment of an internal combustion engine.

Zusammenfassung der ErfindungSummary of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Übertragungselement, insbesondere eine Riemenscheibe oder Rolle für einen Zugmitteltrieb, anzugeben, das in der Lage ist, elektrostatische Ladungen zuverlässig und dauerhaft abzuführen.Of the Invention is based on the object, a transmission element, in particular a pulley or roller for a traction mechanism drive, indicate that is capable of electrostatic charges reliably and permanently dissipate.
Zur Lösung dieser Aufgabe ist bei einem Übertragungselement der eingangs genannten Art erfindungsgemäß vorgesehen, dass das Mittel zum Abführen elektrostatischer Ladungen entweder an einem feststehenden Abschnitt oder an einem drehbaren Abschnitt des Übertragungselements angeordnet ist und den jeweils anderen Abschnitt berührt.to Solution to this problem is in a transmission element of the type mentioned above provided according to the invention, that means for removing electrostatic charges either on a fixed section or on a rotatable section Section of the transmission element is arranged and the each other section touched.
Das Mittel zum Abführen elektrostatischer Ladungen stellt eine elektrisch leitfähige Verbindung zwischen der Riemenscheibe oder Rolle und einem Bauteilabschnitt mit Massepotential her, sodass die Entstehung unerwünschter elektrostatischer Ladungen verhindert wird oder indem diese kontinuierlich abgeleitet werden, bevor es zu einem Funkenüberschlag kommt. Man nimmt an, dass das durch statische Aufladung entstandene Spannungsfeld sich nach dem Erreichen eines ausreichenden Potentialunterschieds spontan entlädt.The A means for removing electrostatic charges provides a electrically conductive connection between the pulley or role and a component portion with ground potential ago, so the formation of unwanted electrostatic charges prevented or continuously dissipated, before there is a sparkover. It is believed that caused by static charge voltage field after reaching a sufficient potential difference spontaneously discharges.
Im Rahmen der Erfindung kann es vorgesehen sein, dass das Mittel zum Abführen elektrostatischer Ladungen als Faden oder Draht ausgebildet ist. Ein Ende des Fadens oder Drahts ist dabei an dem feststehenden Abschnitt oder an dem drehbaren Abschnitt des Übertragungselements angeordnet, das andere freie Ende berührt den anderen Abschnitt. Es kann auch vorgesehen sein, dass das Mittel zum Abführen elektrostatischer Ladungen als Bündel mehrerer Fäden oder Drähte ausgebildet ist. Die mehreren Fäden oder Drähte können ähnlich wie bei einer Bürste zusammengefasst sein, alternativ können die Fäden oder Drähte auf einer Fläche oder beispielsweise in Umfangsrichtung verteilt angeordnet sein.in the According to the invention, it can be provided that the means for the Removing electrostatic charges as thread or wire is trained. One end of the thread or wire is attached to the fixed portion or on the rotatable portion of the transmission element arranged, the other free end touches the other section. It can also be provided that the means for discharging electrostatic charges as a bundle of multiple filaments or wires is formed. The multiple threads or wires can be similar to one Brush can be summarized, alternatively can the threads or wires on a surface or distributed, for example, distributed in the circumferential direction.
Gemäß einer weiteren Ausgestaltung der Erfindung kann es vorgesehen sein, dass das Mittel zum Abführen elektrostatischer Ladungen als Stift, insbesondere als Kohlestift, ausgebildet ist. Ein Kohlestift ermöglicht eine elektrisch leitfähige Verbindung zwischen der Riemenscheibe oder Rolle und einem Bauteil mit Massepotential, indem der Stift oder Kohlestift an dem feststehenden Abschnitt oder dem drehbaren Abschnitt angeordnet ist und den jeweils anderen Abschnitt berührt.According to a further embodiment of the invention, it can be provided that the means for discharging electrostatic charges as a pin, in particular as a carbon pencil, is formed. A carbon pin allows an electrically conductive connection between the pulley or pulley and a component at ground potential by the pin or carbon pin on the fixed portion or the rotatable section is arranged and touches the other section.
Mit besonderem Vorteil kann das Mittel zum Abführen elektrostatischer Ladungen federelastisch an dem feststehenden Abschnitt oder an dem drehbaren Abschnitt anliegen. Dazu kann das Mittel zum Abführen elektrostatischer Ladungen aus einem Federmaterial wie Federstahl bestehen, ebenso kann die federelastische Eigenschaft erzeugt werden, indem einem Draht durch Umformen eine Vorspannung verliehen wird, sodass er bei einer Drehung der Riemenscheibe oder Rolle an dieser anliegt.With Particularly advantageous, the means for removing electrostatic Loads resiliently on the fixed section or on the rotatable section abut. This can be done by the means for removing electrostatic charges made of a spring material such as spring steel exist, as well as the elastic property can be generated by giving a wire a prestress by forming, so that it turns on a pulley or pulley is applied.
Das bei dem erfindungsgemäßen Übertragungselement vorgesehene Mittel zum Abführen elektrostatischer Ladungen kann aus einem Metall oder einer Metalllegierung bestehen, insbesondere eignet sich dazu Kupfer oder nicht rostender Stahl, alternativ kann das Mittel auch aus Graphit hergestellt sein.The in the transmission element according to the invention provided means for removing electrostatic charges may consist of a metal or a metal alloy, in particular is suitable itself to copper or stainless steel, alternatively, the Means also be made of graphite.
Bei dem erfindungsgemäßen Übertragungselement wird es bevorzugt, dass zumindest ein Endabschnitt des Mittels zum Abführen elektrostatischer Ladungen im Bereich der Drehachse angeordnet ist. Vorzugsweise kann das Mittel im Bereich der Befestigung des Übertragungselements angeordnet sein, beispielsweise an einem Schraubenkopf oder an dem freien Ende einer derartigen Befestigungsschraube. Im Bereich der Drehachse ist die Relativgeschwindigkeit Null, sodass kein oder nur ein äußerst geringer Verschleiß zu erwarten ist.at the transmission element according to the invention It is preferred that at least one end portion of the means for Removing electrostatic charges in the area of the axis of rotation is arranged. Preferably, the means in the region of the attachment be arranged of the transmission element, for example on a screw head or on the free end of such Fixing screw. In the area of the axis of rotation is the relative speed Zero, so no or only a very small one Wear is expected.
Gemäß einer alternativen Variante des erfindungsgemäßen Übertragungselements kann es vorgesehen sein, dass das Mittel zum Abführen elektrostatischer Ladungen an einer ein Lager der Riemenscheibe oder der Rolle abdeckenden Kappe angeordnet ist. Wenn das Mittel an der Kappe angeordnet ist, wird beim Montieren der Abdeckkappe auf die Riemenscheibe oder Rolle automatisch der erforderliche Berührkontakt zwischen der Riemenscheibe oder Rolle und einem Bauteil mit Massepotential, beispielsweise einem Schraubenkopf einer Befestigungsschraube, geschaffen. Die erforderliche Ableitung der Ladung über die Kappe kann mittels eines elektrisch leitfähigen Überzugs, einer Leiterbahn oder gegebenenfalls auch über eine Kabelverbindung erzielt werden.According to one alternative variant of the transmission element according to the invention it can be provided that the means for discharging electrostatic Charges on a pulley or roller bearing covering Cap is arranged. When the means is arranged on the cap is when mounting the cap onto the pulley or pulley automatically the required touch contact between the Pulley or roller and a component with ground potential, for example a screw head of a fastening screw, created. The required discharge of the charge over the cap can by means of an electrically conductive coating, a conductor track or possibly also via a cable connection be achieved.
