In the structure, the number of magnetic pieces on two parallel shafts, which are provided with radial magnetic fields, are increased, and the magnetic field directions of a plurality of magnetic pieces are arranged according to certain unfolded angles, so that the influence due to peak values of two poles in magnetic field of each magnetic piece can be reduced obviously, and the transmission is stable in non-contact rotating transmission. The technical scheme for solving the technical problems comprises the following two basic structures: 1. one-to-many transmission mode, i.e., one of two parallel transmission shafts is fixedly provided with a magnetic piece with radial magnetic field, while the other shaft is fixedly provided with a plurality of magnetic pieces which have radial magnetic fields and deflect at angles being 45-60 degrees in sequence; and 2. many-to-many transmission mode, i.e., one of two parallel transmission shafts is sheathed with a plurality of magnetic pieces which have the radial magnetic fields and are unfolded clockwise in sequence with defection at angles being 45-60 degrees, while the other shaft is sheathed with a plurality of magnetic pieces which have the radial magnetic fields and are unfolded anticlockwise in sequence with deflection at angles being 45-60 degrees.

Summary of the invention
For overcoming the wild effect that existing this parallel rotation magnetic transmission structure produces in transmission, the utility model proposes class stable transmission rotation magnetic transmission structure, promptly has the quantity of radial magnetic field magnetic part by on two parallel axes, increasing, and the magnetic direction of these a plurality of magnetic parts is arranged by the angular deflection of certain expansion, the peak value influence at each the two poles of the earth, magnetic part magnetic field is obviously reduced, when discontiguous rotation transmission, make stable drive.
The technical scheme that its technical problem that solves the utility model adopts comprises following two kinds of basic structures:
1, the kind of drive of one-to-many, promptly on two power transmission shafts that are arranged in parallel, wherein be installed with a magnetic part on an axle with radial magnetic field, another axle sets firmly a plurality of spending to the angular deflections of 60 degree with 45 in order and has the magnetic part of radial magnetic field, can reduce the influence of radial magnetic field peak value to the rotation transmission preferably.
2, the kind of drive of multi-to-multi, promptly on two power transmission shafts that are arranged in parallel, wherein be with on axle and a plurality ofly launch 45 in order clockwise and spend to 60 degree angular deflections and have the magnetic part of radial magnetic field, another axle sleeve has and a plurality ofly launches 45 in order counterclockwise and spend to the angular deflections of 60 degree and have the magnetic part of radial magnetic field, use this structure obviously to reduce the peak value at each the two poles of the earth, magnetic part magnetic field influence, when discontiguous rotation transmission, make stable drive.
The beneficial effects of the utility model are, this structure can not only realize steadily rotating transmission, simultaneously by increasing many groups modes in parallel, are implemented in the purpose of carrying out stablizing than high pulling torque transmission in the narrow long and narrow space.
Wherein:,, between each magnetic part, be added with sept in order to reduce the phase mutual interference of magnetic force because the magnetic force direction of the magnetic force direction of each fixing magnetic part and adjacent magnetic part is all inequality on the power transmission shaft;
Wherein: the sept that adds between each magnetic part is a nonmagnetics;
Wherein: the two ends of adding sept between each magnetic part are provided with deflection angle 45 and spend to the location structure of 60 degree, and the magnetic direction deflection 45 of the magnetic part that is installed in the sept two ends is spent between 60 degree;
Wherein:, can on two power transmission shafts, increase a plurality of magnetic parts for improving the magnetic rotation driving torque;
Wherein: about on two power transmission shafts that are arranged in parallel, the magnetic part quantity that sets firmly is symmetric arrays;
Wherein: about on two power transmission shafts that are arranged in parallel, the magnetic part quantity that sets firmly is asymmetric arrangement;
