  • Variable-speed magnetic coupling having radially movable magnet
    Patent number: 11239738
    Abstract: A variable-speed magnetic coupling having a radially movable magnet, comprising a drive disc assembly (I), a driven disc assembly (II), and a speed adjusting device assembly (III). Relative rotation of a speed adjustment sleeve (15) with respect to a drive shaft (16) is achieved by means of contact and fitting of a cylindrical pin (20) with respect to a vertical recess on an inner wall of the drive shaft and to an inclined recess on an inner wall of the speed adjustment sleeve. The speed adjustment sleeve is connected to a circular slotted disc (18) by means of a screw. A permanent magnet (10) is attached to a permanent magnet bearer (9) and inserted into a rectangular through hole of a circular frame (13), and a radial movement of the permanent magnet is enabled by means of a cam and groove sliding block mechanism consisting of the circular slotted disc, the circular frame, the permanent magnet bearer, and the permanent magnet.
