Morphology

epicyclic + gear + train

The compound is compositionally built: 'gear train' clearly denotes a set of gears transmitting motion and 'epicyclic' simply qualifies the type of gear train. However, 'epicyclic' is a technical term referring to a specific orbital/spinning motion of gears whose exact configuration is specialist knowledge and not fully predictable from everyday meanings, so the item is only partially transparent to learners.

Etymology

Epicyclic gear train gets its name from a simple picture: small planet gears 'orbit' a central sun gear while they also 'spin' on their own. So, the name helps you remember it is a compact set of gears that move around a center and turn themselves to change speed and power.
