Title:
ROTATION ACCELERATION DEVICE
Document Type and Number:
Japanese Patent JP2014185694
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotation acceleration device having a simple structure and capable of reducing consumption of energy.SOLUTION: This invention relates to a rotation acceleration device comprising: plate-like rotating members 24 and 26 arranged side by side in a thickness direction and rotatably installed around each of their axial lines; a plurality of crank-like connecting members 48 having a set of supporting segments 48b and 48d rotatably inserted into each of a plurality of through-holes 24c and 26c, a bent part 48c connecting the end parts to each other and a set of fixing parts 48a and 48e; and mass bodies 38 and 40 each of which is arranged in such a way that positions of center of gravity of the mass bodies 38 and 40 may be displaced in such a direction as to increase a rotating force of the rotating members 24 and 26 with respect to the positions of center of gravity of the rotating members 24 and 26. The rotating member 26 is rotated in cooperation with the rotating member 24 in such a way that the through-pass holes 24c and 26c may occupy the same height positions to each other and arranged to transmit a rotation to a fan of a ventilation fan device and then the rotating force of the rotating member 26 is transmitted to the fan to accelerate the rotating force of the fan.
