Abstract

The invention discloses a direct-drive fixed shaft for a wind-driven generator. The direct-drive fixed 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: 2.74% of Cr, 3.82% of Al, 5.73% of Nb, 4.26% of W, 7.59% of Fe and the balance of Ti and inevitable impurities. The alloy material is prepared by steps as follows: 1), fusing Ti, Cr and a Ti-Al alloy under the protective atmosphere; 2), increasing the temperature to 905 DEG C, adding a Ti-Nb alloy, a Ti-W alloy and a Ti-Fe alloy to melt, uniformly stirring the mixture, and performing heat insulation on the mixture and leaving the mixture to stand for 43 min; 3), introducing argon gas, leaving the melt to stand, and cooling the melt to 723 DEG C to obtain the alloy material through casting. The direct-drive fixed shaft for the wind-driven generator has excellent strength, high temperature resistance, wear resistance, corrosion resistance and weather resistance.
