Epicyclic Gears (Planetary gears)

Epicyclic gears (Planetary gears) from MAAG/RENK-MAAG have been used in plants with fast-running turbo machines for over 50 years. They transmit power of up to 45MW; designs with higher outputs being possible today.

High-speed epicyclic gears can be built relatively small as the power is distributed over several meshes. This results in a low power to weight ratio and, together with lower pitch line velocity, leads to improved efficiency. The small gear diameters produce lower moments of inertia, significantly reducing acceleration and deceleration torque when starting and braking.

The coaxial design permits smaller and therefore more cost-effective foundations, enabling building costs to be kept low or entire generator sets to be integrated in containers.
