Research on Torque Production of a New Magnetic Gear


Article Preview

Gear is essential in modern powertrain. While the overwhelming majority of existing gear's power transmission is relying on direct contact of the engagement mechanically, this paper is the study of a novel non-contact magnetic gear. The new structure is especially useful for the requirement of big gear ratio because of its high load ability. Such gear, with high research value, has many advantages over mechanical gears and may replace mechanical gears in many applications. Torque is so basic at factors such as mechanical work, energy consumption, efficiency, operating life and safety. For the basic mechanical components to transmit motion and power----- gears, the torque measurement and analysis seems of great significance in determination and control of load, working parts' intensity design and material selection. Torque analysis is a method which researchers could benefit from much, in order to clarify the practicality of this new gear, it is necessary to utilize theory of torque and the conclusions drawn from simulation to research the structure of this new gear situation. The study can clarify prospect of the gear and provide a theoretical basis for further design.
