  • Turbojet bearing support produced by additive manufacturing
    Patent number: 11585236
    Abstract: A bearing support designed to be secured to a stationary turbojet element for supporting a journal, including a cone which widens from a central portion for supporting the journal to a portion for securing to the stationary element, a cylindrical body extending the portion for securing to the stationary element while surrounding the cone, an upstream skirt carried by the cone for defining an upstream enclosure for the central portion, and at least one downstream revolution element carried by the cone for defining a downstream enclosure for the central portion. The bearing support can be made as a single part produced by additive manufacturing.

  • Shell for reducing overpressure in the vicinity of the upstream seal of a turbojet bearing housing
    Patent number: 11261754
    Abstract: The invention relates to a turbojet bearing housing including a fixed envelope traversed by a rotor, this envelope including a cylindrical end surrounding a seal ensuring the leak tightness of the cylindrical end of the envelope with the rotor, this envelope being equipped with a shell screwed onto the cylindrical end thereof, this shell including radial channels emerging opposite the seal while being arranged so that an air stream traversing the seal towards the housing mainly comes from these radial channels.

  • Installation of calibration gauge for measuring constraints
    Patent number: 9163662
    Abstract: An installation for calibration of a stress gauge for an external bearing block of a turbomachine roller bearing, the bearing block including a radially internal roller bearing race. The installation includes a support table on which the bearing block is attached; an internal roller bearing ring mounted coaxial with the bearing block; a drive shaft driving the ring. The installation also includes a device for applying an axial stress to the bearing block including a support drum on which the internal ring is removably fixed and a connection with the device for applying the axial stress.
