Abstract
The invention discloses a maze type satellite rotary seal mechanism which comprises annular protruding seal pieces A disposed on a rotary shaft and annular protruding seal pieces B disposed on a shaft hole inner wall. The annular protruding seal pieces A and the annular protruding seal pieces B are disposed in a cross manner to form the maze type seal structure. Gaps among the protruding pieces are filled with seal grease, the protruding pieces do not contact with one another, so that friction resistance is lowered. When an electric appliance is mounted in the seal mechanism, possibility of water going into a motor is lowered, and safety performance is increased. The cascade seal rings are better in effect and more stable as compared with single-piece type seal rings.
