AUTOMATIC INFINITELY VARIABLE MECHANICAL TRANSMISSION Russian patent published in 2001 - IPC

FIELD: mechanical engineering; transport engineering; machine tool manufacture. SUBSTANCE: proposed transmission includes input shaft 1 and output shaft 2, carrier 5 with radial axles 6 on which locked internal wheels 7 and external wheels 8 of main satellites are located coaxially, auxiliary satellites 9 and additional satellites 19 which are thrown into engagement with drive central wheel 3 and driven central wheel 4 secured in transmission housing 10 by means of immovable bearing wheel 11 and movable bearing wheel 18; wheel 18 is linked with input shaft 1 by means of hollow intermediate shaft 17 and two pairs of gear wheels (15, 13 and 14, 16). Wheel 13 and 14 are secured on bearing shaft 12 mounted in transmission housing 10 in parallel with axis 0-0. Transfer and conversion of torque in wide ranges at any modes of operation are effected through braking rotation of carrier 5 with its radial axles 6 due to change in directions of vectors of moment of momentum and flywheels 20 connected with them at their simultaneous rotation around axis 0-0 and geometric axes O₁O₁ of radial axles 6 of carrier which is identical to their rotation about central point O¹ of intersection of these axes. EFFECT: extended range of variation of power gear ratio between drive and driven shafts in direct dependence on driven shaft load. 8 cl, 2 dwg
