PLANETARY GEAR FOR AIRCRAFT MADE WITH POSSIBILITY OF HOVERING

摘要

FIELD: aircraft engineering.;SUBSTANCE: invention relates to aircraft engineering, particularly, to helicopters and converter planes reduction gears. Planetary gear for aircraft (1) made with possibility of hovering, has sun gear (7), rotating around first axis (A), fixed crown gear (9) located coaxially with first axis (A) and radially outside relative to sun gear (7). Plurality of planetary gears (11) are placed between teeth of sun (7) and crown gears (9), engaged with them and rotating around corresponding second axes (B), which, in turn, are turned around first axis (A). Lubricant supply device (16) has several nozzles (17) arranged around first axis (A) and sun gear (7) to create lubricant circular flow (F).;EFFECT: better lubrication of sun gear.;12 cl, 7 dwg
