Abstract:
1. An instrumented bearing comprising: a bearing, and a sensor unit for sensing the angular position of a rotatable ring with respect to a fixed ring of the bearing, wherein the sensor unit includes an encoder element which is fastened to the rotatable ring, and a sensing element fastened to the fixed ring, adapted to sense a parameter representative of the rotation speed of the rotatable ring, the encoder element and the sensing element disposed in facing opposition such that the sensing of rotation therebetween is unimpeded by material, wherein the sensing element is mounted in a casing fastened with the fixed ring, and wherein the casing provides a peripheral wall mounted on the fixed ring and provides at least one snap portion adapted to be received in a recess of a surface of the fixed ring, and at least one axial blocking portion adapted to abut against a lateral surface of the fixed ring, and wherein each snap portion and each blocking portion alternate with respect to each other around a central axis (X the snap portion configured to be under tension to prevent radial displacement of the casing relative to the bearing.
