of the inching reducer drive can be added to reflect efficiency losses. P inch = P inch ·(1 + (stage · 0.01)) where stage is the number of reductions between the inching drive motor and the main drive input shaft (or mill pinion if direct driven) Round up P inch to the next standard motor power. This standard motor power becomes the incher ...

Double-Pinion Planetary Gear - MathWorks

Because it contains two planet gear sets, the double-pinion planetary gear reverses the relative rotation directions of the ring and sun gears. The teeth ratio of a meshed gear pair fixes the relative angular velocities of the two gears in that pair.
