1.Ratio: The single-stage transmission i ≤ 99, 2 stage i ≤ 9801;

2.Carrying capacity: There are 9-18 pairs teeth  into the mesh at the same time, can  withstand 2.7 times of overload, and  the input torque is up to 940KN.m;

3. High efficiency: the efficiency of single-stage up to 94-96%;

4.Small size: Under the same output torque conditionsin, the volume is smaller than 1/2-2/3 to  the soft tooth cylindrical gear reducer ;

5. Low noise: small and medium-sized ≤ 78dB, large-scale ≤ 85dB;

6. Long life: rolling friction wear is small, tooth surface is loaded less pressure per unit area, so wear is small, no-pitting;

7. Good maintenance : less wearing parts, wear small, easilyreplacement of Parallel Axis;

8. Price advantage: under the same power, the same reduction ratio, the three-ring reducerhave the obvious price advantagesthe to the more general reducers.
