Friction wheel high-speed suspension shaft centrifugal booster

The invention relates to an explosive motor matching device and discloses a friction wheel high-speed suspension shaft centrifugal booster which comprises a stand equipped with an encloser, wherein a fan boosting device is installed at one side of the stand. The friction wheel high-speed suspension shaft centrifugal booster is characterized in that a suspension spindle penetrates through the fan boosting device, a centrifugal wind wheel set is installed on the suspension spindle, the tail section of the suspension spindle extends into an inner cavity of the stand, three transmission shafts are uniformly arranged on the stand around the suspension spindle, each transmission shaft is provided with a pair of friction wheels, the three pairs of friction wheels are divided into a front set and a back set, three friction wheels in each set are arranged on a same plane and form six-point contact friction transmission at the front part and the back part on the suspension spindle, and one end of each of the three friction wheels extend out of a transmission wheel outside the stand in a same direction. The invention solves the problems of difficult increase of the high rotational speed, large volume, large power consumption and low efficiency of the traditional mechanical booster and is mainly used together with an explosive motor.
