Abstract
PURPOSE: To increase the torque by securing two sun gears and epicyclic gear to same shaft while mounting said two shafts rotatably on single arm and maintaining the number of each gear to specific relation.
CONSTITUTION: Gears (A), (a) are secured to a spindle (S). Gears (B), (b) are geared with gears (A), (a) and secured to shaft (C). The shaft (C) is mounted rotatably to a pedal (P). There is the relation NA+NB=Na+Nb, (Na/Nb)+1= (Na+Nb)+2 between the numbers NA, Na, NB, Nb of each gears JA, a, B, b. Consequently upon rotation of the pedal (P), the gear (a) will rotate through the gears (B), shaft (C), gear (b) and the pedal (P). The rotary force of the gear (a) will try to rotate the crank (CR) in the direction (I) but since the bottom bracket cann't move it is rotated in the direction (II) by the reaction.
