Embodiment Construction
[0032] Figure 1 to Figure 8 Instrumented bearing A is shown on . The instrumented bearing A comprises a bearing B comprising an outer ring 2 forming a non-rotatable element, an inner ring 4 forming a rotatable element, and rolling elements such as balls 6 arranged between the outer ring 2 and the inner ring 4 . The rolling bearing B has an axis of rotation X-X'.
[0033] The instrumented bearing also includes a sensor unit 8 , which includes an encoder 82 , which rotates rapidly with the inner ring 4 . The encoder 82 includes a metal frame 82a and a magnetic ring 82b.
[0034] The sensor unit 8 also comprises a sensor body 84 having an annular shape centered around the axis X-X′ and comprising a plurality of sensing elements 86 fixed relative to the bezel 2 and adapted to be detected by an encoder 82 The rotational speed and direction of the encoder 82 or the angular position is sensed by the change of the magnetic field generated by the rotation about the axis X-X'.
