Rolling bearing with at least one axially limited and deformation sensitive area delivering a deformation signal

摘要

The bearing has a row of rolling bodies placed between rolling tracks (2) of rotating and fixed units. The fixed unit (1) has a free surface (4) elastically deformed by efforts from the bodies. An instrumented zone (5) is defined between surfaces (S1, S2). A sensible material pattern is placed on the zone. The surface (S1) is defined by revolution of a straight line. The line passes via a center of one of the bodies and a center of a contact surface of the body. The surface (S2) is defined by revolution of a normal to the free surface. The normal passes via the center of the contact surface.
