Custom Planetary Gear Model
While the Simscape™ Driveline™ library contains a Planetary Gear, you can create your own custom planetary gear using the Planetary Subcomponents sublibrary. The Custom Planetary Gear example model combines three Sun-Planet Bevel subgears into a masked subsystem to model a coupled planetary gear train. The model uses an Ideal Angular Velocity Source to place a fixed velocity demand on the gearbox input, while damping the system on both the input and output driveshafts with Rotational Damper blocks.
