し回転バランスのよいフライホイール装置を提供するこ
とを目的としている。In the conventional flywheel device, the flywheel was fastened by the tightening force of a tough steel bolt. However, in recent years, the speed has been increased. The tightening force alone is insufficient, and the amount of rotation spread of the taper portion of the flywheel is larger than that of the taper portion of the boss portion 2b. Since the rotation spread amount of the tapered portion of the flywheel is larger than that of the tapered portion of the 2b boss portion, there is a problem that a gap occurs between the contact surface of the tapered portion 33b of the flywheel and the flywheel. In such a state, the flywheel moves in the radial direction, causing a non-rotational engagement, which causes a rotational vibration. An object of the present invention is to solve these problems and to provide a flywheel device with good rotational balance.

する。When the flywheel is rotated at high speed and a centrifugal force creates a gap between the flywheel and the tapered contact surface of the boss, the flywheel comes into contact with both tapered contact surfaces due to the repulsive action of the disc spring. It moves axially and acts to align the boss with the flywheel. The disc spring also acts to prevent the tightening bottle from loosening.

Flange 2c for attaching 33, flywheel 3, 33
Are provided with tapered portions 3a and 33b provided on the inner diameter portion of the device and tapered portions 2a and 2b to be brought into contact therewith. A plurality of tap holes 2d for attaching the flywheels 3 and 33 are provided in the flange portion 2c at equal intervals in the circumferential direction. The flywheels 3 and 33 are provided with a plurality of insertion holes 3c and 33c for the bolts 4 so as to match the tap holes 2d of the flange portion 2c. The bolt 4 for attaching the flywheels 3 and 33 to the flange portion 2c of the boss portion is made of tough steel, and the bolt is provided with a spring steel disc spring 6 and a steel flat washer 5.

And is fixed to the boss. The shaft 1 has bearings 7,77
Supported. This is a flywheel device in which the flywheels 3, 33 and the rotating body A are integrally formed as described above.
The flywheel rotates at high speed because it is tightened with a disc spring inserted bolt, and the flywheel creates a gap in the tapered contact surface due to centrifugal force, but the position where it contacts the contact surface due to the repulsive force of the disc spring The boss and the flywheel are axially moved toward the flange surface of the boss until the boss is aligned with the flywheel. In this way, the flywheel is always kept concentric and can rotate in a well-balanced manner with very little rotational vibration.
