MULTI-LEAF SPRING TYPE VIBRATION DAMPING DEVICE |
摘要 |
<p>Provided is a multi-leaf spring-type vibration damping device capable of suppressing the resonance caused by rotations near the major critical speed of a rotating shaft system and suppressing self-excited vibrations due to rotations at or higher than the major critical speed of the rotating shaft system. In the multi-leaf spring-type vibration damping device, a bearing (9) of a rotating shaft system (6) that includes at least a rotating shaft (4) fit in the bearing and a rotor (5) mounted on the rotating shaft is clamped between a plurality of fixedly mounted and properly spaced-apart multi-leaf springs (11) at the portions near their distal ends, or the plurality of multi-leaf springs contact at those portions near the distal ends with the bearing, thereby to suppress the whirling vibrations of the bearing. The multi-leaf spring-type vibration damping device is characterized in that each multi-leaf spring is made into a multi-leaf spring unit (14) that has a double multi-leaf spring structure in which an auxiliary multi-leaf spring (13) having a structure substantially identical to that of the multi-leaf spring is faced and fixed at its portion near the proximal end of it to a portion near the proximal end of each multi-leaf spring through a spacer (12), and in which the distal end of the auxiliary multi-leaf spring is in advance forced in a direction opposite the multi-leaf spring so as to have a resilient force of a predetermined magnitude.</p> |
