Lubricating structure of single-radial-plate flexible pin shaft type planetary device and wind power gear box

An oil inlet hole is machined in a front end cover, a first annular sealing oil cavity is formed in the junction surface of a planet carrier and the front end cover, and a plurality of first oil through holes penetrating through the front end face and the rear end face of the planet carrier are machined in the planet carrier in the circumferential direction; an oil distribution device is arranged at the vacant positions between the sun gear and the multiple planet gears and comprises an oil distribution flange and a plurality of oil distribution pipes evenly distributed in the circumferential direction of the oil distribution flange, the oil distribution flange is fixed to the rear end face of the planet carrier, and the two ends of a first oil through hole communicate with the first annular sealing oil cavity and the oil distribution pipes correspondingly. And each oil distribution pipe extends to a vacancy between the two adjacent planet gears and the sun gear in the axial direction. A closed space naturall
