The utility model discloses a rotary damping device for achieving the damping effect on input rotary motion. The rotary damping device is characterized by comprising a shell body, a middle shaft and speed reduction components. The shell body is provided with a cylindrical inner side annular wall, the middle shaft is coaxial with the inner frictional surface of the shell body and can be rotationally supported inside the shell body, the middle shaft is provided with a rotary motion input end used for receiving the input rotary motion, each speed reduction component moves in the radial direction relative to the middle shaft and rotates inside the shell body along with the middle shaft, and each speed reduction component is provided with an outer frictional surface opposite to the inner frictional surface of the shell body and capable of sliding on the inner frictional surface in a friction mode. By the adoption of the rotary damping device, the liquid sealing problem caused by using damping liquid is avoided, de
