VARIABLE-SPEED GEAR BOX Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: gear box provides for variation of power-supply rate. Gear box has drive shaft, output shaft, torque converter, sectional planetary mechanism and planetary gear designed to ensure selective drive in reverse direction. Torque converter impeller is coupled for transmission of driving force to one of members of sectional planetary mechanism. Runner is coupled for transmission of driving force to other member of sectional planetary mechanism. Torque converter stator is positioned between impeller and runner by means of overrunning clutch. Sectional planetary mechanism is actuated by drive shaft. Said construction makes it possible to obtain high moving force, preferable operational characteristics, and continuous and noiseless operation. EFFECT: enhanced efficiency. 16 cl, 28 dwg, 1 tbl
