The invention discloses a double-row compound planet and NW planet combined wind power gear box structure. According to the wind power gear box structure, a double-row compound planet structure and an NW planet structure are combined to form a two-stage planet wind power gear box; the first-stage gear adopts a double-row compound planet structure, the second-stage gear adopts a traditional NW planet structure, and the first-stage gear and the second-stage gear adopt transmission structures with planet carriers fixed and inner gear rings serving as driving rotation pairs, so that input power can be divided step by step, the load borne by the single-stage gear is reduced, and the transmission efficiency is improved under the same power and transmission ratio. Compared with an existing method, the tooth width and the radial size of the compound planetary gear train and the parallel stage can be reduced, the size and the weight of the gear box achieve higher power density, and the manufacturing cost of the gear b
