Power motor can be damaged, to effectively save production cost.One active magnetic wheels is installed on to one end of driving shaft, it is another
A driven magnetic wheel is installed on one end of driven shaft, and keeps two one sides of the magnetic force structural member with magnetic radial parallel opposite, root
According to the size of torsion, there are certain air gap distances, form non-contact transmission device, when driving shaft one end operates, in magnetic field
Under the action of power, driven shaft is driven to rotate synchronously；
2, the material that the active magnetic wheels in the present invention and driven magnetic wheel use is that non-magnet material and strong magnet form, and is made
It is good with performance.Respectively by the magnetic wheel of one entirety of three parts structure composition in active magnetic wheels and driven magnetic wheel, pedestal and upper
Lid is screwed by screw thread, and intermediate magnetic ring, which is fixed on internal group, becomes a magnetic force structural member that can be worked, active magnetic
Wheel and the radial parallel discharge arranged side by side of driven magnetic wheel reach synchronous rotation by the attracting effect of repelling each other of magnetic force.
3, the present invention is dustless clean environment, will not generate dust because of friction, solves to need to seal transmission dynamic environment, have
It solves the problems, such as oil leak to effect, does not contact that there will be no wear phenomenons between active magnetic wheels and driven magnetic wheel, do not influence
Power transmission.
