Description
Summary:Mechanical gear boxes have the construction of direct mechanical contact, whose disadvantages are low efficiency, noisy, complicated lubrication and easy to produce vibrations to be damaged and so on. Especially for the occasions with the requirement of big gear ratio, the mechanical multi-speed gears are needed, which makes the shortcomings of mechanical gear transmission even more obviously. In this paper, the construction of a novel magnetic gear, which has no direct mechanical contact between the driven axis and load axis, is proposed, the principle of the gear ratio is introduced and the production of the reluctance torque of the magnetic gear is analyzed. The results show that the gear ratio of this magnetic gear can be even larger.
