AUTOMATIC STEPLESS GEARING Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: gearing contains driving shaft 1 and driven shaft 2, basic carrier 3 mounted on hollow driving shaft 4 fixed coaxially to the driving shaft and provided with radial axles 5, basic 6 and additional 21 intermediate wheels mounted for their mutually independent rotation on the radial axles. Intermediate wheels 6 are engaged with fixed supporting wheel 8 mounted inside housing 7. Additional intermediate wheels 21 are engaged with movable supporting wheel 19 mounted on countershaft 20 for rotation in the same direction with the driving shaft. The countershaft is connected to the driving shaft through two pairs of gears 18,16 and 15,17 and supporting shaft 14 mounted inside housing 7 of the gearing. Carrier 10 of the differential is mounted on the driving shaft. The differential carries the intermediate wheels on its axles 12 which. The intermediate wheels engage with center wheel 9 mounted on the driven shaft and center wheel 11 mounted on the driving shaft. EFFECT: automatic changing of the torque in dependence on load on the driven shaft, enhanced reliability at any rotation speed of the driven shaft. 9 cl, 2 dwg
