Abstract
Mechanical transmission for aeronautical applications, in which a kinematic chain housed inside a leakproof casing has a main power input shaft actuated by a thermal propulsion unit and a secondary power input shaft which can be actuated externally by means of a rotating head which can be coupled to the secondary shaft in a releasable manner by means of a magnetic assembly so as to allow rotation of the secondary shaft at low speed and when the main propulsion unit is inactive.
Claims10
A low-speed mechanical transmission to power a main power input shaft able to be actuated by a main propulsion unit and a secondary power input shaft housed inside an external casing;
- an auxiliary actuating assembly releasably coupled to the secondary shaft and arranged to rotate the secondary shaft when the main propulsion unit is inactive, the auxiliary actuating assembly comprising an external actuating head and an angular coupling operating between the actuating head and the secondary shaft the angular coupling comprising a first magnetic device coupled to the secondary shaft in an angularly fixed position, and a second magnetic device mounted on the external actuating head.
