A wind generating set with bottom driving comprises a wind power transmission portion, a mechanical driving portion, a speedup portion, a speed regulation generating portion, and a control portion. The power generated by rotation of blades under the effect of wind power is transmitted to a main shaft through a wheel hub. The main shaft is connected with two bevel gear sets for changing direction and speeding up twice, and an output shaft is a crankshaft which is formed by three connecting rod necks, the torsion moment generated by an impeller is transmitted to the crankshaft at the bottom of a tower cylinder through transmission steel pipes. The output shaft at the bottom of the tower cylinder connects a gear case to carry out speedup, six groups of speed regulation generating devices areintroduced, each group comprises two sets of speed regulation generating devices, each of which comprises a sprocket wheel, a clutch, a buncher stepless gear, and a generating set. The present invention has the advantages of low cost, stabilized generating frequency, direct access, convenience in market popularization, and requires no expensive frequency converter, and therefore, has significant economic benefit and wide application prospects.
