Title (EN) ACOUSTIC EMISSION MEASUREMENTS OF A BEARING ASEEMBLY
(FR) MESURES D'ÉMISSION ACOUSTIQUE D'ENSEMBLE PALIER
Abstract:
(EN) The present invention pertains to a bearing assembly comprises a rolling element bearing (110) and an acoustic emission unit (120). The rolling element bearing (110) is provided with at least a bearing seal (140, 140'), characterized in that the acoustic emission unit (120) is arranged on the bearing seal (140, 140'). The present invention provides an improved method for measuring acoustic emissions in a bearing assembly.
(FR) La présente invention concerne un ensemble palier qui comprend un palier à élément roulant (110) et une unité d'émission acoustique (120). Le palier à élément roulant (110) comprend au moins un joint de palier (140, 140'), caractérisé en ce que l'unité d'émission acoustique (120) est agencée sur le joint de palier (140, 140'). La présente invention propose un procédé amélioré de mesure d'émissions acoustiques dans un ensemble palier.
