Torsional vibration reduction device and control device for torsional vibration reduction device

摘要

PROBLEM TO BE SOLVED: To provide a control device of a torsional vibration reducing device capable of suppressing generation of abnormal noise due to an impact of an inertial body or the like when the rotation of a rotating body is stopped. SOLUTION: In a torsional vibration reducing device, a rolling element 4 is located within a predetermined angle range A in a rotating direction of a rotating body 2 centered on an RP directly above the rotation center of the rotating body 2 in the vertical direction. When the weight of the inertial mass body 4 pushes the rotating body 2 to the lowest position toward the rotation center side, the inertial mass body 3 is held by the rotating body 2 so as to support the suspended state, and the rotating body 2 is held. , The relative position with the output shaft 26 is determined and arranged so that none of the rolling elements 4 is positioned within the predetermined angle range A when stopped at a position of a predetermined rotation angle together with the output shaft 26. There is. [Selection diagram] Fig. 4
