PLANETARY GEARBOX AND WIND POWER DEVICE

A planetary gearbox for a wind power device, and a wind power device. The planetary gearbox comprises a planetary shaft (10), a planetary gear (40) and a planetary carrier (50). The planetary gear (40) and the planetary carrier (50) are assembled on the planetary shaft (10). The circumferential surface of the planetary shaft (10) in contact with the planetary gear (40) can be divided into a bearing region and a non-bearing region. At least one hydraulic oil cavity (101) is axially arranged on the circumferential surface, and the hydraulic oil cavity (101) is arranged in the non-bearing region. In the planetary shaft structure, it can be ensured that the area of the bearing region is sufficiently large during normal operation, and the area of the bearing region being too small during reverse operating is also avoided, and thus stress is not concentrated at the edge of the oil cavity.
