Stationary Gear

These gears are secured to the front or rear housing and, along with the bearings, support the eccentric shaft.

They also mesh with the rotor's internal gear, becoming the guide for the planetary motion of the rotor along the trochoid surface of the rotor housing.

Eccentric Shaft

This shaft is the output shaft of the RE.

When the rotor journal, which is eccentric, receives the energy of the ignited gas via the rotor, there is rotation around the center of the eccentric shaft.

The center of the eccentric shaft is hollow and is used as an oil passage to lubricate the various parts.
