  • Turbo engine comprising a damping fluid film for damping a guide bearing of a shaft of the turbo engine and method of adjusting the thickness of such a damping fluid film
    Patent number: 9631493
    Abstract: A turbine engine including a casing, a turbine engine shaft extending axially, a guide bearing for guiding the turbine engine shaft in the casing, the guide bearing including an inner circumferential ring rigidly connected to the turbine engine shaft, an outer circumferential ring fitted in a housing of the casing, and gripping rolling members, and a damping cavity configured to receive a damping fluid to form a damping fluid film for damping the guide bearing, the cavity being delimited radially between an outer surface of the outer ring and an inner surface of the housing. The outer surface of the outer ring and the inner surface of the housing are conical surfaces.
    Type: Grant

  • Fluidic dampening film supply method for a guiding bearing of a turbine engine shaft
    Patent number: 9234462
    Abstract: A fluidic dampening film supply method for a guiding bearing of a turbine engine shaft, said turbine engine being known to vibrate according to at least one given vibratory mode, said turbine engine being adapted to enter in resonance at a given resonance speed (wr) for said given vibratory mode, a monitoring range (P) being defined around the resonance speed (wr), a method wherein the fluidic dampening film of the guiding bearing being only supplied with fluid when the rotation speed of the turbine engine belongs to the monitoring range (P).
