First Gear

First Gear





Gear rotation speed





^ Suppose the gear ratio in first gear is i1,





^ From the result NR=0 in formula (1), the relation between the gear ratio in first gear and the rotation speed of the planetary gear set is indicated in the formula below.
(ZRR+ZSR)NC=ZSRNS
^ Therefore,





^ As a result, the gear ratio in first gear is 2.785.
