Abstract
The invention discloses a direct-drive rotating shaft for a wind-driven generator. The direct-drive rotating shaft comprises a main metal body, wherein the main metal body is made of an alloy material, and the alloy material comprises components in percentage by weight as follows: 4.67% of Ce, 7.82% of Pb, 8.13% of Sc, 6.97% of Zr, 5.47% of Sb and the balance of Ti and inevitable impurities. The alloy material is prepared by steps as follows: 1), fusing Ti, Ce and a Ti-Pb alloy under the protective atmosphere; 2), increasing the temperature to 955 DEG C, adding a Ti-Sc alloy, a Ti-Zr alloy and a Ti-Sb alloy to melt, uniformly stirring the mixture, and performing heat insulation on the mixture and leaving the mixture to stand for 42 min; 3), introducing argon gas, leaving the melt to stand, and cooling the melt to 733 DEG C to obtain the alloy material through casting. The direct-drive rotating shaft for the wind-driven generator has excellent strength, high temperature resistance, wear resistance, corrosion resistance and weather resistance.
