Transmission Ratios in a Planetary Gear Train

Application ID: 142021


This example showcases a helical planetary gear train composed of a sun gear, ring gear, carrier, and five planet gears. Three cases are analyzed by in turn fixing the ring gear, sun gear, and carrier.

For each configuration, a transient multibody analysis is performed to determine the angular velocities of all gears under a specified input velocity. The resulting displacements and angular velocities are plotted, and the transmission ratios are compared for the three configurations.

This model example illustrates applications of this type that would nominally be built using the following products:
