The invention relates to a lubrication wind power gear box planet gear and bearing structure. A wind power gear box comprises a pipe shaft, a transparent cover symmetrically arranged at one end of the pipe shaft, a planet carrier arranged at the other end of the pipe shaft, a flange coating the pipe shaft and positioned between the planet carrier and the pipe shaft, a sun gear parallel to the pipe shaft, a pin shaft, a planet wheel and a gear ring; a copper ring is arranged between the transparent cover and the pipe shaft; the pipe shaft is coated by the copper ring; the copper ring is fastened on the transparent cover; an oil cavity is formed between the flange and the planet carrier; an oil inlet hole of the transparent cover is communicated with an oil hole of the copper ring, an oil hole of the pipe shaft and the oil cavity in sequence; the oil cavity is respectively communicated with an oil hole I in one side of the planet carrier and an oil hole II in the other side of the planet carrier; the oil hole I is communicated with the oil hole of the pin shaft; the change of an oil way from a static piece to a rotating piece is finished through the transparent cover, the copper ring and the pipe shaft to satisfy the oil supply requirements of planet gears and bearings; and the oil way is connected through a part without such accessories as oil pipes and pipe joints, so that materials are saved, and the cost is reduced.
