Dynamic damping procedure of a particular power tree of a supercritical tree and implementation damping architecture

摘要

Dynamic damping method in a power shaft (10) comprising a speed reduction gear (15) in a drive pinion (16), framed by a set of upstream (12) and downstream (14) tree supports of the gear, characterized in that the set of supports (12, 14) is extended downstream by at least one supplementary support (20) coupled to a compressible damping (26) in orbital motion to form an axially offset downstream damping (20, 26) with respect to the upstream support (12) in relation to the power gear (15).
