Abstract:
1. A soundless winch, comprising: a body, which is a tubular cylinder having an end on which a flange is formed, the tubular cylinder being provided, at each of front and rear ends thereof, with a stepped section adjacent to the ends, the body receiving a bearing, a one-way bearing, and a friction ring to fit therein; a reel, which has two ends each forming a stop flange, a threaded rod projecting from a center of one of the ends of the reel, the threaded rod having an end forming a fitting hole, the reel being received, with the threaded rod thereof, in the hollow cylinder of the body in such a way that the threaded rod of the reel is exposed outside the body to allow the bearing, the one-way bearing, and the friction ring to couple to the reel; and a handle, which is fit to the threaded rod of the reel that is exposed outside the body by a pin fit in the fitting hole so that forward or reverse rotation of the handle controllably sets the friction ring and the one-way bearing in a released condition or a braking condition.
