| description | The utility model relates to the technical field of industrial fans, in particular to an overspeed protection assembly of a fan and an engine. The overspeed protection assembly of the fan comprises a rotating shaft of the fan and a driving shaft penetrating through the rotating shaft, the rotating shaft and the driving shaft are coaxially arranged, and the rotating shaft and the driving shaft are connected through a connecting piece so that the rotating shaft and the driving shaft can rotate relatively; an elastic telescopic piece is arranged between the rotating shaft and the driving shaft, one end of the elastic telescopic piece is fixedly connected with the inner wall of the rotating shaft, and a friction block is arranged at the other end of the elastic telescopic piece; in the initial state, the friction block abuts against the outer wall of the driving shaft under the action of the elastic telescopic piece so that the driving shaft can drive the rotating shaft to rotate. And when the rotating speed of t |
