| 摘要 |
The invention relates to a device comprising a mechanical bearing includi ng two coaxial bushings, i.e. an outer one (1) and an inner one (2) with one bushing being fixed relative to the frame of the machine and the other bein g capable of rotation, a rolling member (3) being trapped between the bushin gs and capable of displacement, characterised in that the device comprises a t least one positioning non-conductive means (4) tightly mounted on the bear ing bushing that is fixed relative to the frame of the machine, said non-con ductive positioning means (4) including at least one positioning housing for at least one conductive member, defining a first capacitor armature (5) at a distance from the conductive portion of the rotating bushing, and defining the second capacitor armature (6), said non-conductive positioning means (4 ) being connected to at least one partitioning means (8), the partitioning m eans (8) defining a space (7) between the armatures (5, 6) that forms a diel ectric insulating environment and sealing said insulating environment while being in contact with a portion of the surface of the rotating bushing.</SDO AB> |
