POWER-DRIVEN VARIABLE-SPEED TRANSMISSION Russian patent published in 2003 - IPC

FIELD: machine engineering. SUBSTANCE: power-driven infinitely variable transmission includes driving and driven shafts; eccentric transducer; central gear wheel; arranged uniformly along circle gear wheels engaged with central gear wheel; coaxial to said gear wheels free-running mechanisms. Driving members of free running mechanisms are joined with eccentric transducer; driven members through torsion shafts are joined with gear wheels. Toothed clutch is mounted between driving and driven shafts for driving direct transmission. Using of torsion shafts with twisting angles at tension less than fatigue strength allows to distribute loads between free running mechanisms. Invention allows to lower by 2 - 2.5 times maximum loads of transmission members when the same torque is transmitted. EFFECT: possibility for receiving dynamics coefficient on driven shaft almost equal to unit. 2 cl, 1 dwg
