| 摘要 |
<p>The invention concerns a transmission mechanism between at least one accessory (1, 2) and the motoring members (3, 4) driving a rotorcraft rotor (5), selectively, individually or jointly. An intermediate shaft (13) is interposed between a main shaft (7) driving the rotor (5) and a secondary shaft (12) driving the accessory (1, 2) from a motoring member (3) assigned to its motorization. Said intermediate shaft (13) is directly engaged on the main shaft (7) and engaged on a pinion gear (23) driving the accessories via free wheels (16, 17), to enable the pinion gear (23) to be driven either from the motoring member (3) or from the main shaft (7) in combined motorization with the rotor (5), itself driven by the motoring member (4) or in autorotation in case of failure of the two motoring members.</p> |
