Holding Or Fastening Of Disk On Rotational Shaft
(AREA)
Abstract
Improved system of variable speed drive of the disk holder plate of phonographic disc players, characterized in that the rotary movement is transmitted from the electric motor shaft to the disk holder plate through a cone mounted directly on said shaft and a wheel free friction that rests against the surface of said cone and against the underside of the disc holder plate and that by means of a graduation mechanism can slide in axial direction without losing its contact with the surface of the cone and the underside of the mentioned plate .
