VARIABLE SPEED DRIVE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: variable speed drive comprises input 1 and output 2 shafts, hollow driving conical friction member 3 mounted on input shaft 1, at least one driven conical friction member 4 arranged with a radial clearance along generatrix relative to driving conical member 3, magnet installed in the latter with a provision for axial movement, and ferromagnetic liquid contained in gap. At least one additional driven conical friction member 4 is installed with a radial clearance along generatrix relative to driving conical friction member 3 in such a manner that the latter is disposed between driven conical friction members. Output wheel of multiple-flow wear transmission is installed on output shaft 2 while input wheels are meshed by means of corresponding driven conical friction members. EFFECT: improved design. 2 cl, 4 dwg
