SUTOMATIC INFINITELY VARIABE 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 in which coaxial locked internal wheels 7 and external wheels 8 of main satellites 9 and additional satellites 18 which are thrown into engagement with drive central wheel 3 and driven central wheel 4 located on one side from carrier 5 secured in housing 10 of transmission by means of immovable bearing heel 11 and movable bearing ring 17 which is linked with input shaft 1 by means of hollow intermediate shaft 16 mounted coaxially relative to input shaft 1 and three gear wheels 15, 13, 14 for rotation relative to input shaft in opposite direction. Wheel 13 is secured on bearing shaft 12 in transmission housing 10 in parallel with axis 0-0. Transmission and conversion of torque in wide ranges and at any modes of operation are effected through braking rotation of carrier 5 with its radial axles 6 due to change in direction of vector of moment of moment of all satellites and flywheels 19 connected with them at their simultaneous rotation around axis 0-0 of transmission and geometric axes 0₁-0₁ of radial axles 6 of carrier which is identical to rotation relative to central point 0¹ of intersection of these axes. EFFECT: extended range of gear ratio between input and output shafts in direct dependence on output shaft load. 9 cl, 2 dwg
