The invention concerns an instrumented bearing (1) comprising an outer ring (2), an inner ring (4), at least a row of rolling elements (6) arranged between a raceway of the outer ring (2) and a raceway of the inner ring (4), an assembly detecting rotation parameters comprising a sensor unit (11) int
The invention concerns an instrumented bearing (1) comprising an outer ring (2), an inner ring (4), at least a row of rolling elements (6) arranged between a raceway of the outer ring (2) and a raceway of the inner ring (4), an assembly detecting rotation parameters comprising a sensor unit (11) integral with the non-rotating ring and supporting a sensing element (14) and a rotating coding member (16) forming a rotating part with the rotating ring, the coding member comprising an active part moving in rotation in front of the sensing element, the sensing unit and the non-rotating ring forming a fixed part. The rotating part comprises indexing means external to the active part of the coding element and capable of positioning at an angle said rotating part relative to a reference of the fixed part in a position wherein the coder generates in the sensing element a reference signal.

1. An instrumented rolling-bearing device, of the type comprising an outer ring, an inner ring, at least one row of rolling elements which are arranged between a raceway of the outer ring and a raceway of the inner ring, and an assembly for detecting rotational parameters comprising a sensor unit secured to the non-rotating ring and supporting a sensor element, and a rotary encoder member forming, with the rotating ring, a rotating part, the encoder member comprising an active part rotating past the sensor element, the sensor unit and the non-rotating ring forming a stationary part, wherein the rotating part comprises an indexing means external to the active part of the encoder member and capable of angularly positioning said rotating part with respect to a reference of the stationary part in a position in which the encoder generates a reference signal in the sensor element. 2. The device as claimed in claim 1, wherein the indexing means is supported by an intermediate part secured to the rotating part. 3. The device as claimed in claim 2, wherein the intermediate part is a sleeve secured to the rotating ring. 4. The device as claimed in claim 3, wherein the sleeve is removable from the rotating ring. 5. The device as claimed in claim 1, wherein the indexing means is formed directly on the rotating ring. 6. The device as claimed in claim 1, wherein the indexing means is formed directly on the encoder member. 7. The device as claimed in claim 1, wherein the indexing means consists of a protrusion, a groove, a notch or an optical mark. 8. The device as claimed in claim 1, wherein a terminal for leading wires out of the sensor unit comprises the reference of the stationary part used for the angular positioning of the means of indexing of the rotating part. 9. The device as claimed in claim 1, wherein the indexing means and a terminal for leading wires out of the sensor unit are aligned when the encoder delivers the reference signal in the sensor. 10. The device as claimed in claim 1, wherein the indexing means also forms a reference means when producing the active part of the encoder. 11. A method of pre-indexing a device as claimed in claim 1, wherein the rotating part is rotated until the reference signal is delivered, in that the two parts, rotating and stationary, are immobilized in this relative angular position, and in that an indexing means is placed on the rotating part in a given angular position with respect to a reference of the stationary part.
