| description | The invention discloses a rotating shaft assembly, and relates to the field of motors. In an outer rotor type air feeder adopting a sliding bearing, due to size limitation, the size of a permanent magnet is small, the attraction force to a rotating shaft is small, when the rotating shaft of a motor is subjected to large axial force, the phenomenon that the rotating shaft moves in the axial direction occurs, and the rotating shaft even breaks away from the bearing in the serious situation. The device comprises a base body, a shaft sleeve, a rotating shaft, a magnet, a thrust pad, a shock pad and a stop sleeve, the shaft sleeve is embedded in the upper middle portion of a cylindrical cavity, the stop sleeve is arranged on the lower portion of the cylindrical cavity, the stop sleeve presses the magnet, the thrust pad and the shock pad, the rotating shaft is in rotating fit with the shaft sleeve, a surrounding neck groove is formed in the lower end of the rotating shaft, and the stop sleeve is provided with an an |
