Damping device of small wind driven generator

The utility model discloses a damping device of a small-sized wind driven generator, which comprises a generator set body, a central shaft and hemispherical fan blades, the input end of the generator set body is fixedly connected with a movable sleeve, the inner wall of the movable sleeve is provided with six movable grooves, and the six movable grooves are annularly distributed at equal intervals. Through the arrangement of the first damping rubber block, when airflow in air is unstable to drive the center shaft to vibrate, the center shaft can drive the first damping rubber block to vibrate up and down in the movable groove, and then the first damping rubber block can collide with a second damping rubber block; then the damping property of rubber is used for damping the vibration force, so that the problem that the service life of the central rotating shaft is shortened, the maintenance frequency is improved, and the service life of the central rotating shaft is prolonged due to aggravated wear of the centr
