| 摘要 |
The present invention relates to a device for magnetic coupling between two rotary driving and driven shafts, comprising two neighbouring transverse discs respectively securely fastened to the two driving and driven shafts and each carrying, at their periphery, a succession of magnets. This device is characterised in that the driving shaft 1 and driven shaft 2 are parallel to one another and spaced apart by a distance which is less than the sum of the radii of the two discs 3, 4 so that, viewed in the longitudinal direction, the trajectories A, B followed by the magnets 5, 6 carried by the two discs 3, 4 intersect in a zone 7 which is sufficiently wide so that, along this zone, the successive magnets 5 carried by the driving disc 3 drive the magnets carried by the driven disc 4. <IMAGE>
