FRICTION REVERSIBLE VARIABLE-SPEED DRIVE Russian patent published in 1998 - IPC

FIELD: continuous conversion of rotary speed and torque power. SUBSTANCE: in symmetrically arranged and parallel linked planetary gears, type 3K, satellites have aligned working tapered surfaces - main and two auxiliary ones. Satellites make up bevel gearings with central wheels: a friction transmission with a driven wheel, and gear transmissions with a drive and fixed wheels. System that makes up compressive force in friction transmission uses, in addition to self-tightening mechanism, a loading mechanism which is linked to driven shaft by means of gearings and a differential gear. Satellite balancing system is furnished with rotary supports. Drive and driven shafts of variable-speed drive are aligned. EFFECT: enhanced reliability. 6 cl, 9 dwg
