In the present embodiment, whole transmission process are as follows: the fixation of sun magnet-wheel 1 is set on the input shaft 7, described
The rotation of input shaft 7 drives the sun magnet-wheel 1 to rotate, and the input shaft 7 is identical as the angular speed that the sun magnet-wheel 1 rotates,
Since several first planet magnet wheels 2 are arranged around the sun magnet-wheel 1, the sun magnet-wheel 1 is not stalling dynamic situation
Under, the magnetic field outside the sun magnet-wheel 1 constantly changes, so that several first planet magnet wheels 2 be driven not stop also with sun magnet-wheel 1
Rotation, first planet magnet wheel 2 and the connection of the second planet magnet wheel 3 rotate synchronously, so the second planet magnet wheel 3 is in the first planet
It being rotated under the drive of magnet-wheel 2, second planet magnet wheel 3 is identical as the angular speed that the first planet magnet wheel 2 rotates, and several described
Two planet magnet wheels 3 determine the setting of magnet-wheel 4 around described, and described to determine the fixed setting of magnet-wheel 4, the rotation of the second planet magnet wheel 3 makes institute
The magnetic field stated outside the second planet magnet wheel 3 constantly converts, and under the influence of a magnetic field, several second planet magnet wheels 3 are around described
Determine the rotation of magnet-wheel 4, second planet magnet wheel 3 is arranged on the planet wheel disc 5, so second planet magnet wheel 3 drives
The planet wheel disc 5 rotates, and the fixation of planet wheel disc 5 is set on the output shaft 8, and the planet wheel disc 5 drives described
Output shaft 8 rotates.
In the present embodiment, the transmission ratio and the sun magnet-wheel 1, the first planet magnetic of the input shaft 7 and the output shaft 8
The 2, second planet magnet wheel 3 of wheel, 6 quantity of magnet for determining to be arranged on magnet-wheel 4 are related, pass through first planet magnet wheel 2, the second planet
6 quantity of magnet of 3 periphery of magnet-wheel setting is different, realizes the first order speed change of Magnetic drive, first planet magnet wheel 2, the second row
Star magnet-wheel 3 rotates synchronously, and the angular speed of rotation is identical, and the first planet magnet wheel 2 of setting, 3 periphery of the second planet magnet wheel are different
6 quantity of magnet keeps the outer diameter of the first planet magnet wheel 2, the second planet magnet wheel 3 different, and when angular speed is identical, outer diameter is not
