Bearing support with an instrumented movement and coder for an information recorder unit
First Claim
1. An instrumented rolling bearing comprising a non-rotating ring, a rotating ring, at least one row of rolling elements positioned between two raceways of the rotating and non-rotating rings, and an information sensor assembly comprising a non-rotating sensor unit and a rotating encoder provided with an active part, the encoder and the sensor unit being separated by a gap, wherein the encoder comprises a substrate made of electrically non-conducting material and an electrically conducting thin layer supported by the substrate, the substrate rotating as one with the rotating ring.

Abstract
The invention relates to a bearing support with an instrumented movement (1), comprising a non-rotating bush (2), a rotating bush (3), roller elements (4), arranged between the rotating (3) and non-rotating (2) bushes and an information recorder unit, with a sensor (7) and a coder (8), comprising a substrate (16) made from an electrically non-conducting material and a thin layer (17) of electrically-conducting material, supported by the substrate (16). The substrate (16) is fixed in rotation with the rotating bush (3).
