AUTOMATIC STEPLESS GEARING Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: gearing contains driving 1 and driven 2 shafts, basic carrier 3 with radial axles 5, whereon basic 6 and additional 11 intermediate wheels are mounted, and differential whose pinion carrier 10 is mounted on the driving shaft, second center wheel 13 is mounted on the driving shaft, and first center wheel 12 is mounted on the hollow countershaft 4 located coaxially to the driving shaft. The first center wheel of the differential and the basic carrier are mounted on the hollow countershaft. The basic intermediate wheels 6 are engaged with fixed enter wheel 8 mounted inside housing 7 of the gearing and additional intermediate wheel 11 are engaged with movable supporting wheel 9 mounted on the shaft. EFFECT: automatic changing of the torque and rotation speed of the driven shaft in dependence on load on the driven shaft. 9 cl, 2 dwg
