MEC Overdrive Unit

The Overdrive Unit, "MEC", includes a set of epicyclical gears that represent an application of a simple epicyclic arrangement of the type used in a motor vehicle overdrive.

Simple epicyclic set consists of:

• Sun gear that rotates together with the input shaft.
• Planet gears whose carrier can rotate.
• Ring gear that rotates together with the output shaft.

In the "MEC" unit the power reaches the epicyclic gear through the central sun gear, that is to say, the input shaft is joined to the central sun pinion and the output power is obtained at the output shaft because it is joined to the ring.

This unit allows the student to study the reduction ratios of overdrive, as well as torque conversion.
