PROBLEM TO BE SOLVED: To make a vibration reducing device utilized when reducing vibration more compact in size.SOLUTION: A vibration reducing device is equipped with a dynamic mass 22, elastic bodies 23-1 to 23-2, 24-1 to 24-2, which apply elastic forces to the dynamic mass 22 so that the dynamic mass 22 vibrates in parallel to a damping direction 25, a control mass 26, an actuator 27 which expands and contracts in parallel in an expansion and contraction direction 34, and a moving direction conversion mechanism 28 which moves the control mass 26 to the dynamic mass 22 so that the control mass 26 moves in a damping direction 25 to the dynamic mass 22 by the expansion and contraction of the actuator 27. The actuator 27 is supported by the dynamic mass 22 so that the expansion and contraction direction 34 does not become parallel to the damping direction 25. By this, a vibration reducing device 19-i can be formed so that the dimension of the damping direction 25 becomes smaller compared with other vibration reducing devices in which the expansion and contraction direction 34 and the damping direction 25 are equal, the device can be made more compact in size.

60 Pitch changing and lead lag attenuating device for helicopter JP28374287 1987-11-10 JPH01127493A 1989-05-19 SATO TETSURO
PURPOSE: To prevent relative displacement between a sleeve and a pivot so as to reduce a lead lag by connecting an elastomeric damper, a flex beam, a torque arm, a pitch sleeve, an elastomeric pivot, a damper, and an arm with each other. CONSTITUTION: In assembly of a pitch changing and lead lag attenuating device 6, a through hole 2a is bored in a flex beam 2, a bushing 13 is mounted inside the through hole 2a, and an assembly constructed of an elastomeric pivot 7 and a torque arm 12 connected together by means of a nut 10 is inserted into the inside of the bushing 13. After an elastomeric damper 9 is inserted from the upper/lower side of the arm 12 so as to be connected to the pivot 7 via the beam 2 and a nut 8 and a pitch sleeve 3 is inserted into the beam 2, the sleeve 3 and the arm 12 are connected together via a nut 11. If a lead lag is generated in a rotor blade 4 and a relative position between the beam 2 and the sleeve 3 is changed because a clearance between the end face of the beam 2 and a pitch change link 5 is changed from 1 to 1', a relative displacement between the sleeve 3 and the pivot 7 can be prevented.
