Abstract:
(EN) The invention relates to a device and a method for reducing a shaft voltage (UW) on a shaft or a bearing voltage (UWL) between a shaft and a housing. A rolling bearing supports the shaft against the housing and has a rolling bearing capacitance (CWL). Electrically parallel to this, another capacitance is present between the shaft and the housing (CW-G) as a result of the arrangement of the shaft and housing. According to the invention, an additional bypass capacitance (CBypass) is also arranged electrically parallel thereto.
(FR) L'invention concerne un dispositif et un procédé permettant de réduire une tension d'arbre (UW) sur un arbre ou une tension de palier (UWL) entre un arbre et un carter. Un palier à roulement supporte l'arbre par rapport au carter et comprend une capacité du palier à roulement (CWL). Une autre capacité entre l'arbre et le carter (CW-G) est présente de manière électriquement parallèle à celle-ci du fait de la disposition de l'arbre et du carter. Selon l'invention, une capacité de dérivation (CBypass) supplémentaire est également agencée de manière électriquement parallèle à celle-ci.
(DE) Vorrichtung und Verfahren zur Reduktion einer Wellenspannung (UW) an einer Welle bzw. einer Lagerspannung (UWL) zwischen einer Welle und einem Gehäuse. Dabei lagert ein Wälzlager die Welle gegenüber dem Gehäuse und weist dabei eine Kapazität des Wälzlagers (CWL) auf. Elektrisch parallel dazu liegt eine weitere Kapazität zwischen Welle und Gehäuse (CW-G) durch die Anordnung von Welle und Gehäuse vor. Erfindungsgemäß wird eine zusätzliche Bypass-Kapazität (CBypass) ebenfalls elektrisch parallel dazu angeordnet.
