Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Lager, insbesondere ein Wälzlager, mit einer als Klauenpolgenerator ausgebildeten Energieerzeugungseinheit. The invention relates to a bearing, in particular a roller bearing, with a trained as Klauenpolgenerator power generation unit.
Aufgabe der ErfindungObject of the invention
Es ist die Aufgabe der Erfindung, den Aufbau eines mit einem axial gesicherten Lagers, das eine als Klauenpolgenerator ausgebildete Energieerzeugungseinheit aufweist, zu verbessern. It is the object of the invention to improve the construction of an axially secured bearing which has a power generating unit designed as a claw pole generator.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß im wesentlichen dadurch gelöst, dass die magnetisch leitende Verbindung der beiden Klauenringe im wesentlichen durch den magnetisch leitenden Abschnitt eines axialen Sicherungselementes, insbesondere durch eine Wellenmutter, hergestellt ist.This object is achieved essentially by the fact that the magnetically conductive connection of the two claw rings is essentially made by the magnetically conductive portion of an axial securing element, in particular by a shaft nut.
Das axiale Sicherungselement, das die Stellung des ersten Lagerrings auf der Welle axial fixiert und das insbesondere als eine Wellenmutter oder eine Nutmutter ausgebildet ist, bewirkt zusätzlich zu der axialen Fixierung die magnetisch leitende Verbindung der beiden Klauenringe und somit die Schließung des magnetischen Flusses auf der Seite der Klauenringe. Damit entfällt ein Flussleitelement, das zwischen den beiden Klauenringen angeordnet ist und den Bauraum der Induktionsspule einschränkt. The axial securing element, which axially fixes the position of the first bearing ring on the shaft and which is designed in particular as a shaft nut or a slot nut, causes in addition to the axial fixation the magnetically conductive connection of the two claw rings and thus the closure of the magnetic flux on the side the claw rings. This eliminates a flux guide, which is arranged between the two claw rings and limits the space of the induction coil.
Da bei der Auslegung des Lagers ein Bauraum für das axiale Sicherungselement, beispielsweise die Nutmutter oder die Wellenmutter, routinemäßig eingeplant wird, ist kein zusätzlicher Bauraum vorzuhalten, um die magnetisch leitende Verbindung der beiden Klauenbleche auszubilden, so dass sich der konstruktive Aufwand vereinfacht. Since in the design of the bearing a space for the axial securing element, such as the nut or the shaft nut is routinely planned, no additional space is vorzuhalten to form the magnetically conductive connection of the two claw plates, so that simplifies the design effort.
Vorzugsweise ist vorgesehen, dass zwischen dem Sicherungselement und einer Stirnfläche des ersten Lagerrings ein radial verlängerter Abschnitt des ersten Klauenrings angeordnet ist, wobei das Sicherungselement flächig auf dem verlängerten Abschnitt aufliegt. Die vergrößerte Kontaktfläche des Sicherungselementes zu dem ersten Klauenring vereinfacht die Ausbildung eines die Grenzfläche überschreitenden magnetischen Flusses. It is preferably provided that between the securing element and an end face of the first bearing ring, a radially extended portion of the first jaw ring is arranged, wherein the securing element rests flat on the extended portion. The enlarged contact surface of the securing element to the first claw ring simplifies the formation of a magnetic flux bordering the interface.
Vorzugsweise ist vorgesehen, dass ein axial abgestellter Abschnitt des zweiten Klauenrings an einer axialen Kontaktfläche des Sicherungselementes flächig anliegt. Die vergrößerte Kontaktfläche des Sicherungselementes zu dem zweiten Klauenring vereinfacht die Ausbildung eines die Grenzfläche überschreitenden magnetischen Flusses.It is preferably provided that an axially parked portion of the second claw ring rests flat against an axial contact surface of the securing element. The enlarged contact surface of the securing element to the second claw ring simplifies the formation of a magnetic flux exceeding the boundary surface.
