(1) accurate transmission, operating without fear of sliding caused by the trouble, with a relatively stable speed ratio;
(2) Transmission efficiency is very high, can reach more than 95%! The most obvious effect is also the advantages of energy-saving aspects: maintenance is very convenient, do not need manual lubrication, maintenance costs are relatively low;
(3) The speed is larger than the region, the theoretical speed can reach 1:10, the thread speed is up to 50m/s, with very big power rotation, can reach the kilowatt instantly;
(4) can be applied to the relatively long-term regional transmission, the center distance can be within 10m.
