The invention relates to the technical field of wind power gear boxes, in particular to a multi-stage planet carrier bearing arrangement method which comprises a box body, a first-stage planet carrier, a second-stage planet carrier and bearings. The first-stage planet carrier and the second-stage planet carrier are axially arranged in sequence and are fixedly arranged in the box body; an inner ring of the bearing is fixedly connected with the box body, and an outer ring is fixedly connected with the planet carrier; the first-stage left bearing and the first-stage right bearing are arranged at the two ends of the first-stage planet carrier, and the second-stage left bearing and the second-stage right bearing are arranged at the two ends of the second-stage planet carrier. The first-stage left bearing and the second-stage right bearing are overlapped in the radial direction; adjusting end covers are arranged at the joints of the first-stage left bearing and the box body and the joints of the second-stage left b
