The block of gear (called cluster gear) 2 is free to rotate on a shaft which is supported in casing. If the casing is fixed, the epicyclic gear train is reduced to a Z or N-1+: (11.9) 1 11.5 TOROUE TRANSMITTED BY EPICYCLIC GEAR TRAIN When an epicyclic gear train transmits power, torques are transmitted from one Two procedures are presented for obtaining the analytical expression for the efficiency of any planetary gear train. The first employs the speed and torqueLet us compare a planetary gear train with a conventional one, with fixed gear axes, designed for the same gear ratio of angular velocities of the input and output The determination of optimal design of the planetary gear train with a lightweight, a short center distance, and a high efficiency is an important issue in the Jan 24, 2020 - Compound Epicyclic Gear Train When two or more epicyclic gear train are connected in series, the combination is known a compound epicyclic gear train.
