Abstract

Il riduttore comprende una ruota dentata solare (5) collegata con la turbina, un organo portasatelliti (6) atto a sopportare una pluralità di ruote dentate satelliti (7) ingrananti con la ruota dentata solare e con una corona dentata (8) fissata all'incastellatura del motore; in base all'invenzione l'organo portasatelliti (6) comprende un primo elemento di forma sostanzialmente anulare (10) il quale è provvisto di coppie di sedi (11) per perni (13) su ciascuno dei quali ruota una delle ruote dentate satelliti (7), un secondo elemento (17) collegato al compressore è provvisto di una pluralità di bracci assiali (18) ciascuno dei quali è atto ad inserirsi in una cavità (16) del primo elemento e mezzi di collegamento (19) atti a collegare l'estremità di ciascuno dei bracci suddetti ad una zona (20) del primo elemento (10) la quale è posizionata sostanzialmente alla stessa distanza dalle due sedi (11) di ciascuno di dette coppie di sedi.
