Firm annulus, soft annulus with wave generator common calls 3 big in harmonic positive drive (graph 1) . Its characteristic is bulk light, structure reachs small, weight simply assemble convenient. It is orgnaization of decelerate of synthesis of OK and independent group, poor fast orgnaization reachs the orgnaization that add model, and return can with other drive form, wait like planetary drive, worm wheel deputy drive and helix drive undertake assorted in order to achieve first-rate drive result. The worker that because the outstanding characteristic of 3 big structures is,is engaged in mechanical main transfer machinery offers more innovation train of thought. 3 big when institute of technology of Beijing harmonic drive makes its are soft annulus material is high strenth alloy steel, use method of scientific and reasonable cold, hot-working, assured effectively soft annulus performance characteristics. The cam of wave generator machines what the method is this institute to have a technology only, the science that uses the grinding rate such as high accuracy hard profiling namely machines a method, make sure cam over all dimension and working surface outline spend an error to all be less than 0.

01mm. Machine of harmonic gear decelerate (graph 2) have drive taller than precision of big, drive, carrying capacity big, drive smooth, volume is minor reach noise low good point, be applied extensively to each domains of mechanical drive. The machines and tools of harmonic gear decelerate that institute of technology of Beijing harmonic drive makes has type of more than 10 products, hundreds kinds of drive is compared, in harmonic gear ratio enclothe on rate very extensive. Graph 3 big of 1 harmonic positive drive -- steel annulus, soft annulus pursue with wave generator the high-tech field that at present its product basically uses product of machine of decelerate of 2 harmonic drive at Electromechanical unifinication, what if the actuating device of miniature radar antennae, monitoring is photographed,resemble is various a cloud stage, solar energy collect heat board dogs device, monocrystal preparation device, medical treatment uses the machine that treat cancer actuating device, machine tool feed and orgnaization of high accuracy fixed position, polychromatic printing machine, large-scale color.
