摘要： An epicyclic gear system (A) has a sun gear (2), a ring gear (4) located around the sun gear (2), and planet gears (6) located between and engaged with sun (2) and ring (4) gears. In addition, it has a carrier (8) including a carrier flange (32) that is offset axially from the planet gears (6), and carrier pins (34) that project from the carrier flange (32) into the planet gears (6), each with a shank (40) anchored to the flange (32) and a head (42) remote from the flange (32). Between the planet gears (6) and the carrier pins (34) are double row tapered roller bearings (50), so that the planet gears (6) rotate on the pins (34). Each bearing (50) includes an inner race (52) having tapered raceways (64 and 66) presented away from the carrier pin (34), opposing tapered raceways (64 and 66) on the planet gear (6), and tapered rollers (58) organized in two rows between the raceways (64 and 66). Whereas the carrier pin (34) is cantilevered from the carrier flange (32), the inner race (84) is cantilevered from the head (42) of carrier pin (34). In operation, the pins (34) will deflect in one direction under torque applied to the carrier (8) and resisted by the planet gears (6), and the inner races (52) will deflect in the opposite direction, so that the axes about which the planet gears (6) rotate remain parallel to the central axis of the system (A). The pins (34) may have grooves (46) to enhance their deflection.

摘要： An epicyclic gear system has a sun gear, a ring gear, and planet gears between the sun and ring gears. In addition, it has a carrier including a carrier flange offset axially from the planet gears and carrier pins that project from the flange into the planet gears, each with a shank anchored to the flange, a head remote from the flange, and a groove between the shank and head. Between the planet gears and the carrier pins are bearings, each including an inner race and rollers between the inner race and planet gear. Whereas the carrier pins are cantilevered from the carrier flange, the inner races are cantilevered from the heads of the carrier pins. The grooves in the pins enhance pin deflection, so that the axes about which the planet gears rotate remain parallel to the central axis of the system.
