  • Method for detecting a critical defect in a ceramic rolling element
    Patent number: 11650170
    Abstract: Method for detecting at least one critical defect in a ceramic rolling element providing the steps of capturing a plurality of two-dimensional digital radiographic images of the ceramic rolling element; digitally filtering each radiographic image; delineating, on the basis of the filtered image, at least one region liable to comprise the critical defect; constructing stereoscopically a virtual model of the ceramic rolling element having the region; comparing the dimensions of the delineated region with a plurality of predetermined threshold values, and, when the dimensions are greater than the threshold values, generating an alarm signal.
    Type: Grant
    Filed: May 3, 2021
    Date of Patent: May 16, 2023
    Assignees: Aktiebolaget SKF, SKF Aerospace France S.A.S.
