2Individual; So-called magnet case is meant the magnetic conductor that does not possess permanent magnetism among the present invention, for example the structure of being made by silicon steel plate; So-called embedded mobile magnet case is meant the mobile magnet case that moves that is located between the first magnetic gear train and the second magnetic gear train on the direction perpendicular to the plane that axis constituted of the axis of the first magnetic gear train and the second magnetic gear train.
So-called magnetic gear can be a permanent magnetism magnetic gear among the present invention, also can be electromagnetism magnetic gear, and electromagnetism magnetic gear needs direct current supply at work.
In order to keep the beam transmission in magnetic field effectively in magnet case, magnet case should be established every magnetosphere among the present invention, and described can be certain thickness air layer every magnetosphere, also can be made up of the material of other magnetic property differences.In order to improve magnetic field transmission efficient, also should be provided with between the magnetic gear for the magnetic gear train every magnetosphere, guarantee the magnetic field non-interference of each magnetic gear.
Advantage of the present invention:
That magnetic gear shift disclosed in this invention has is simple in structure, energy consumption is little, do not need the advantage of lubricating.
