Development of a Magnetic Planetary Gearbox

IEEE Transactions on Magnetics, 2008
In this paper, we describe a new design for a magnetic planetary gearbox. We discuss the theory of operation and a simulated design. We constructed and verified the simulation by measuring the transmitted torque and cogging torque. A magnetic planetary gearbox operates like a mechanical planetary gearbox, except that it is contact-free and needs no ...

Design and analysis of the bearingless planetary gearbox

2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2017
High performance legged and mobile manipulating robotic platforms require light weight actuators with high torque density, efficiency, and accuracy. This paper introduces a new type of high reduction bearingless gearbox which is based on a gearbox with double-row planetary pinion, and can achieve high reduction ratios in a single composite stage.

Dynamic Simulation of Planetary Gearbox

Key Engineering Materials, 2013
Planetary gears are the most popular transmission machinery in large reduction ratio circumstances, which is because of the advantages of compactness, co-axial and high power efficiency. Accurate dynamic model is crucial when planetary gears are used in precise positioning and controlling systems.
