TH71772A - Rotating shaft anti-vibration device - Google Patents

Abstract

DC60 (03/02/48) to provide a device capable of suppressing vibration with a simple and low-cost configuration, but still stable in the device for preventing vibration of the rotating shaft with mass parts. In such a way, a 52 anti-oscillation mass part with a rotating shaft is provided, and an anti-oscillation mass 52 is supported as Moves in the axial direction of the rotating shaft while friction is created Later, the anti-oscillation mass 52 is supported so that it cannot move in the direction perpendicular to the axis of the rotating shaft. In addition, parts An anti-oscillation mass 52 is supported to allow rotation perpendicular to the axis of rotation. To provide a stabilizing device with a simple and low cost configuration, but still stable in the device for anti-vibration. Of a rotating shaft with a mass fraction is such that an anti-oscillation mass 52 rotating with a rotating shaft is provided and an anti-oscillating mass 52 is supported in the axial direction of the rotating shaft while That has created friction Later, the anti-shake mass piece 52 is supported so that it cannot move in the direction perpendicular to the axis of the rotating shaft. In addition, an anti-oscillation mass 52 is supported so that it can rotate in a direction perpendicular to the direction of the rotating shaft.
