    摘要: A prestressing device extending about an axis between a first plane that is substantially perpendicular to the axis and a second plane that is substantially parallel to the first plane and axially offset relative to the latter. The device includes a first annular body extending in the first plane, and a first series of at least three tabs, each of which is connected to the first body and extending in an essentially radial direction, each of the tabs of the first series including a planar surface extending in the second plane. This arrangement ensures surface contact between the parts of the elements to be subjected to prestressing. The device can be used for example for a rotor, and for example for a rotor of an unducted propeller for a turbine engine.

    摘要: An assembly in a turbine engine for controlling plural toothed pivotally-mounted blades arranged in azimuth around the axis of the turbine engine and including an actuator ring controlling a position of the blades. Racks mounted on the ring present corresponding sets of teeth meshing with the set of teeth of a respective one of the blades to place it in a selected angular position, and they are held in the radial direction by radial positioning mechanism fastened to the blade. Each rack is mounted on the ring by plural guides spaced apart circumferentially around the ring, that connect together movements of the rack and of the ring in the circumferential direction, and that are configured to slide relative to the ring, for each guide in its own radial direction, and relative to the rack in a direction of movement that is substantially radial and specific to the rack.

    摘要: A variable pitch blade propeller hub for a turbomachine with a longitudinal axis includes a polygonal ring supporting the blades, concentric with the longitudinal axis and including two spaced parallel annular end flanges between which are diametrically fastened, by root areas arising from the annular flanges, collars with cylindrical radial housings to receive the blades. The collars are equi-angularly distributed at the lateral periphery of the polygonal ring and separated from each other by intermediate areas with through-openings. The also includes connectors connecting the polygonal ring to a turbine rotor element of the turbomachine. The intermediate areas defined between two concentric collars and the annular end flanges include elements for reinforcing the collars that are arranged radially and/or tangentially and fastened at least to the lateral walls of two consecutive collars.
