    • PROBLEM TO BE SOLVED: To provide a planet mechanism which can achieve a large reduction gear ratio while suppressing an increase in weight. SOLUTION: The planet mechanism 10 comprises: a sun gear 11 as an input; a fixed ring gear 12; a planet carrier 13 as an output; a first planet gear 15 which is supported by the planet carrier 13, and engaged with the sun gear 11; and a second planet gear 16 which is supported by the planet carrier 13, and engaged with the ring gear 12. A first rotation shaft 15a of the first planet gear 15 is arranged in the vicinity of a planet carrier rotating shaft 13a of the planet carrier 13 rather than a second rotation shaft 16a of the second planet gear 16. Torque is transmitted to the second planet gear 16 from the first planet gear 15. COPYRIGHT: (C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a planet mechanism which can achieve a large reduction gear ratio while suppressing an increase in weight.
      SOLUTION: The planet mechanism 10 comprises: a sun gear 11 as an input; a fixed ring gear 12; a planet carrier 13 as an output; and a planet gear unit 14 supported by the planet carrier 13. The planet gear unit 14 comprises: a shaft 17; a first planet gear 15 which is connected to the shaft 17, and engaged with the sun gear 11; and a second planet gear 16 which is connected to the shaft 17, and engaged with the ring gear 12. The planet gear unit 14 rotates around a first rotating shaft 14x with respect to the planet carrier 13. The planet carrier 13 rotates around a second rotating shaft 13x. The first rotating shaft 14x crosses the second rotating shaft 13x.

    • PROBLEM TO BE SOLVED: To provide a power transmission device for a helicopter capable of balancing thrust load generated in a helical gear engaging part and dead weight of a driving shaft and minimizing axial direction displacement amount generated by a torque distribution of a double helical structure.
      SOLUTION: This transmission device is provided with a first vertical shaft 12 provided with a driven side bevel gear 22 engaged with a driving side bevel gear 21 provided in an output shaft 11 and a pair of upper and lower driving side helical gears 23A and 23B, second vertical shafts 13A and 13B provided with driven side helical gears 24A and 24B and rotor shaft driving gears 25A and 25B, and a main gear 26 rotating integrally with a rotor shaft 2. In two pairs of helical engaging parts with which the driving side helical gears 23A and 23B and the driven side helical gears 24A and 24B are engaged, each of tooth trace inclination directions is made an opposite direction, and tooth trace inclination angles have an angle difference to cancel the thrust load corresponding to the dead weight of the first vertical shaft.
