AUTOMATIC STEPLESS MECHANICAL TRANSMISSION Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: driving central bevel gear 4 and driven central bevel gear 5 are in meshing with internal planet pinions 8 and external planet pinions 9, respectively, relative to geometric axis 0-0, main planet pinions being fitted on radial axles 7 of carrier 6. Additional plant pinions 10 arranged, similar to main plant pinions, are brought into meshing with central bevel fixed support wheel 11 secured in transmission housing. Main planet pinions 8, 9 and additional planet pinion 10 are provided with massive rims 12 increasing mass of said plant pinions to allow them serving as flywheels. EFFECT: provision of stepless automatic change of transmitted torque and driven shaft speed. 5 cl, 1 dwg
