Micro Planetary Gear — Principle
Know-how meets know-do
The flexible planetary gear is the outstanding feature of the new MPG Micro Planetary Gear Series — a consequential result of our engineering and fabrication competence. The use of planetary gears with radial flexibility keeps lost motion to < 30 angular minutes without any backlash-adjustment mechanism.

Flexible gears are the solution
Frequently encountered problems with conventional prestressed gears, such as worsening torque ripple, noise and wear behaviour, as well as the significant increase in friction torque are solved by using flexible planetary gears. A technology also successfully employed by Micro Harmonic Drive Gears.
