Friction gear permanent magnetic entrainment means

A friction gear permanent magnetic entrainment means for rolling transmission of motion in combination with a magnetic-technical system having one magnetic circuit comprising at least two magnets and at least one operating air gap, said magnetic circuit including a frame being composed of symmetrically arranged permanent magnets and symmetrically arranged mild iron or steel parts arranged between analogous poles of the magnets forming central frontal surfaces drawn into the interior of the frame, which central frontal surfaces oppose one another forming an operating gap with opposite polarities in the direction of magnetizing, including drive rollers and off-drive rollers disposed in a common casing, said drive rollers being supported on axes which form oppositely polarized elements of a magnetic circuit closing the magnetic system, block magnets and associated pole shoes located outside of said casing and forming a part of said magnetic-technical system, said axes being connected to said block magnets and their associated pole shoes, said block magnets and associated pole shoes being mounted on both sides of frontal surfaces of said drive rollers, and said axes being secured by said pole shoes.
