    摘要: The invention relates to a method for detecting a structural defect in a mechanical assembly including a rotary member, wherein said method comprises a preliminary analysis for identifying a frequency characteristic of the occurrence of the defect over a revolution of said member, and the iterative steps of: measuring the instantaneous rotation speed of the rotary member; angularly sampling said measure so as to obtain a sampled signal representative of the instantaneous rotation speed of the member; carrying a harmonic space analysis of the sampled signal in order to obtain a spectrum of the instantaneous rotation speed of the member; monitoring the amplitude of the spectrum for the characteristic frequency so as to derive the occurrence of a corresponding defect based on said amplitude.

    摘要: The aim of the invention is to provide a bearing ring which is characterized by a reliable and maintenance-free protection from frictional corrosion on the fits of the bearing ring, said protection being already effective during assembly. To achieve this aim, the bearing ring (1) has a wall (9) that is provided with a frictional corrosion-resistant layer (10) in at least those regions (12) that are in contact with a machine component (15) via a fit (14) when assembled.
