ABSTRACT:
The hybrid fluid bearing comprises a fixed body, a tubular part made of a nonmetallic material, mounted inside the body and having an internal bore which defines a cylindrical bearing surface, leaving a small amount of clearance relative to the shaft, which is provided with an annular magnetic circuit constituted by rectified laminations. A fixed magnetic circuit made of laminations defines a series of poles and notches disposed concentrically around the outside of the tubular part, with electromagnetic windings being disposed in the notches around the poles and being fed with electricity from servocontrol loops which receive signals from at least one vibration detector disposed on the fixed body. The cylindrical bearing surface has a series of recesses formed therein, said recesses being distributed around the circumference of the tubular part and being connected to means for feeding them with fluid and for removing fluid therefrom. Sealing means are also provided. This hybrid fluid bearing has the capacity of being heavily loaded while simultaneously highly attenuating vibrations reaching the fixed body thereof.
