The invention discloses a lubricating method for a sliding bearing in two-stage planetary gear transmission. According to the technical scheme, the lubricating device is characterized in that for a first-stage planetary gear reducer, a lubricating oil channel is formed in a machine shell support, lubricating oil is conveyed to a planetary shaft under the pressure P, and the lubricating oil lubricates the contact position of the planetary shaft and the planetary gear through an additional oil channel, a fixed annular sliding way, a rotating circular sliding way and an oil outlet hole; a sealing ring is installed outside the rotating circular slide way, the fixed annular slide way is fixedly connected to a machine shell support, the rotating circular slide way is fixedly connected with a planet shaft, the rotating circular slide way rotates around a sun wheel shaft, and the sun wheel shaft is a center shaft of the wind power gearbox. The structure and the lubricating mode of the second-stage planetary gear redu
