Title (EN) SENSORIZED BEARING UNIT
(FR) UNITÉ DE PALIER MUNIE DE CAPTEUR
Abstract:
(EN) The present invention defines a bearing unit comprising a bearing provided with one or more strain sensors, where the bearing comprises an inner ring and an outer ring, and where the one or more strain sensors (10) comprises a sensing element (14) integrated on a support member (12). According to the invention, the support member is a thin flat plate made of a metal material and is attached to a surface (5) of the bearing only by means of a first weld seam (21) and a second weld seam (22) located at first and second lateral ends of the support member. The present invention also defines a method of attaching the strain sensor (10) to the bearing surface (5).
(FR) La présente invention porte sur une unité de palier comprenant un palier qui comporte un ou plusieurs capteurs de contrainte, le palier comprenant une bague intérieure et une bague extérieure, et les un ou plusieurs capteurs de contrainte (10) comprenant un élément de détection (14) intégré sur un élément de support (12). Selon l'invention, l'élément de support est une plaque plate mince réalisée en un matériau métallique et fixée à une surface (5) du palier au moyen d'un premier cordon de soudure (21) et d'un second cordon de soudure (22) uniquement, disposés aux première et seconde extrémités latérales de l'élément de support. La présente invention porte également sur un procédé de fixation du capteur de contrainte (10) à la surface du palier (5).
