Geometric modeling and torque analysis of the magnetic nutation gear drive

Forschung Im Ingenieurwesen/Engineering Research, 2017
This paper proposes a novel magnetic nutation gear drive (MA-ND) which offers several advantages compared to the traditional mechanical one in terms of contact-free, low noise and vibration, inherent overload protection, no need of lubrication and low-loss energy. Firstly, the working principle of the proposed MA-ND is introduced.
