Abstract:
1. Protection device ( 1 ) for an encoder ( 2 ) in a rolling bearing ( 3 ) presenting an outer race ( 5 ) which is arranged in contact against a fixed support ( 6 ), the device ( 1 ) being interposed between the encoder ( 2 ) itself and a reading sensor ( 17 ) which is supported by the support ( 6 ) itself, and comprised a fixing race ( 18 ) which is shrink fit onto the outer race ( 5 ) of the bearing ( 3 ) and which is frontal to a shoulder ( 15 ) of the support ( 6 ), and a protection shield ( 19 ) which extends from the fixing race ( 18 ) towards an inner race ( 4 ) of the bearing ( 3 ) in a position which is frontal to both the encoder ( 2 ) and the sensor ( 17 ); the device ( 1 ) being characterised by the fact that it comprises a sealing element ( 30 ) which is integral to the fixing race ( 18 ) and which is interposed directly between the fixing race ( 18 ) and the support ( 6 ) in order to statically waterproof the support ( 6 ).
