Title
(DE) WÄLZKÖRPER UND SENSIERVERFAHREN
(EN) ROLLING ELEMENT AND SENSING METHOD
(FR) ÉLÉMENT ROULANT ET PROCÉDÉ DE DÉTECTION
Abstract
(DE) Die Erfindung geht aus von einem Wälzkörper für ein Wälzlager (26) mit wenigstens einer Sensoreinheit (12). Es wird vorgeschlagen, dass die Sensoreinheit (12) dazu vorgesehen ist, bei wenigstens einem Betriebsvorgang, bei welchem sich der Wälzkörper bewegt, einen Schlupf des Wälzkörpers zu sensieren.
(EN) The invention relates to a rolling element for a roller bearing (26) comprising at least one sensor unit (12). The invention states that the sensor unit (12) is provided for sensing a slip of the rolling element during at least one operating step in which the rolling element moves.
(FR) L'invention concerne un élément roulant pour un palier à roulement (26) comprenant au moins une unité de détection (12). L'unité de détection (12) permet de détecter un patinage de l'élément roulant, pendant au moins un processus de fonctionnement au cours duquel l'élément roulant se déplace.
