      MB series planetary friction meenical infinite speed reducer

      (1) Brief description

      Planet conic disc stepless speed reducers are designed by foreign and domestic advanced technologies, widely used in light industries such88 foods, pbarmacy, plastics, paper making, porcelain, tobacco. leather, beavy industries such as machine tools. petroleum, metallurgy, andtransportation services.Main advantages:

      1.High strength: under sbock load or in reversed rotation, reliable performance, pecise rasmission, no backward force, enough strength;2.Wide speed regulation range; 5, speed ratio varies between 1.45-7.25;3.High precision in speed regulation: 0.5-1.0r/min;

      4.Stable performance: rasmission parts undergo special heat treatment, precisely processed, well lubricated, stable operation, ltt noise,long if;

      S.Coaxial structure: input spindle and out spindle are coaxial, rotate in a same direction, compact and light;

      6.High adaptability: can be combined with various speed reducers for low-speed stepless speed reduction, with excellent adaptability.

2. Structure and fundamental

      Aplanet conic disc stepless speed reducer is composed ofinput spindle, output spindle, planet mechanism, speedre-gulation mechanism and so on, fundamental:

      Conical sun wheel (12) and pressure disc (13) are pressedbya set of disc springs (14), input spindle (15) is coupled withsun wheel, to compose a pressed input unit. A set ofconical planetwheels (10) are between sun wheel and pressure disc inside,conical fix ring (11) and speed regulation cam (9) outside, wheninput unit rotates, as fixed ring and speed regulation cam arefixed, planet wheel rll around the ring, and revolves aroundinput spindle, through planet wheel and sliding bearing(3), drivesplanetrack (2) and output spindle (1)t0 rotate, and outputs torque.
