PIVOT LINKAGE DEVICE WITH BEARINGS COMPRISING MEANS FOR PROTECTION AGAINST HIGH VOLTAGE TRANSIENTS

摘要

The current invention relates to a pivot linkage device (20) comprising at least one rolling bearing (21) comprising at least one inner cage (213), one outer cage (211) and a plurality of rolling elements denoted as the bearing components, the device (20) further comprising means for protection against high voltage transients, characterized in that said protection means are exclusively formed by said bearing components, said bearing components being loaded by loading means arranged in such a manner that a direct electrical connection exists between these components. The current invention also relates to a method for protecting a bearing against high voltage transients by applying a preloading to the bearing's components.
