METHOD AND ARRANGEMENT OF MEASURING A MECHANICAL BEARING OSCILLATION

摘要

An arrangement and a method of measuring a mechanical bearing oscillation within a bearing, the bearing supporting a rotating shaft which is coupled to an inner ring of the bearing, the arrangement comprising: a bolt arranged in a force fit with an outer ring of the bearing in order to excite, by the bearing oscillation, a bolt oscillation; a sensor mechanically coupled to the bolt for registering the bolt oscillation, the bolt oscillation being indicative of the bearing oscillation.
