The brush of joint and support keep geo-stationary.The brush of revolution conductive contact connects external power source at a high speed.Two-way switch control into
Enter the sense of current of motor, thus change motor internal rotor and turn to the relative of center driving axle.Motor internal rotor driven gear axle
Rotating, gear drive makes screw turns, screw turns, and feed screw nut (being fixed together with magnetic piece fixed disk assembly) moves vertically
Dynamic, thus change the distance (magnetic field coupling gap) between magnetic piece fixed disk assembly and inductive disks assembly, to reach variable speed energy saving
Purpose (change of magnetic field coupling gap will cause the change of magnetic coupling inner and outer rotors slip, the namely change of input and output rotating speed),
Lever lazy-tongs ensure the magnetic piece fixed disk component synchronization adverse movement of both sides.
Fig. 2, Fig. 3 show gear drive ball-screw speed adjusting gear, and gear drive ball-screw speed adjusting gear is by ball-screw group
Part 3-1, gear drive (gear 3-6 and gear shaft 3-8 composition) and lever lazy-tongs (lever 3-12,3-15 etc.
Composition) combine.In Fig. 2, spacing back-up ring 3-18 is used for ensureing that synchronizing bar 3-17 will not occur axial float, and 3-19 is micro-
Adjusting spring, 3-1 is ball-screw assembly, and 3-2 is support.
