Title:
TORSIONAL VIBRATION REDUCTION DEVICE
Document Type and Number:
Japanese Patent JP2021060063
Kind Code:
A
Abstract:
To provide a torsional vibration reduction device which can improve a yield of a material of the device as a whole.SOLUTION: In a torsional vibration reduction device 1 which comprises a planetary rotation mechanism 18 for performing a differential action by a center rotation element S, a ring rotation element R and a carrier rotation element C for holding a planetary rotation element P, and in which one of the rotation elements S, C and R is set as one of input elements S, C and R, the other one of the rotation elements S, C and R is set as one of output elements S, C and R, another one of the rotation elements S, C and R is set as one of inertia elements S, C and R, the input elements S, C and R and the output elements S, C and R are connected to each other via an elastic body 20, and an additional inertia body 19 is added to the inertial elements S, C and R, at least either of the inertia elements S, C and R and the additional inertial body 19 is formed of a plurality of split pieces 19s, Rs which are split in a circumferential direction, and the split pieces 19s, Rs are connected to each other in the circumferential direction, thus forming the annular bodies S, C, R and 19.SELECTED DRAWING: Figure 4
