Abstract
The invention discloses a concentric type permanent magnet gear cascading transmission gear, comprising an outer magnetic ring assembly, a magnetic adjusting ring I assembly, an inner magnetic ring I assembly, a magnetic adjusting ring II assembly, an inner magnetic ring II assembly, an input assembly and an output assembly. The power transmission form of the invention is power dividing; big transmission ratio, rotate speed and torque output can be realized in a small structural space; for the permanent magnet D, the magnetic adjusting ring II assembly, and the inner magnetic ring II assembly are participated in the rotating movement, and the magnetic adjusting ring II needs to overcome the resistance of the magnetic ring II assembly, thus the movement required can be generated, and thereby transmitting larger power and drive ratio. Therefore, the power dividing method of the invention is essentially different from the power dividing of the traditional mechanical gear; except for the power dividing through a mechanical power drive branch which is the same as the mechanical gear, the dividing can be carried out again through a magnetic field coupling relationship at the inner part of the magnetic gear. Therefore, the concentric type permanent magnet gear cascading transmission gear is more compact in structure, smaller in space, and bigger in cost advantage.
