Title:
PLANETARY GEARBOX AND WIND POWER DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/212859
Kind Code:
A1
Abstract:
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). On the planetary shaft (10), two axial ends of the planetary gear (40) are respectively provided with a first axial bearing member (60, 70) and a second axial bearing member (20, 70). An end surface of the first axial bearing member (60, 70) and/or the second axial bearing member (20, 70) that is in contact with the planetary gear (40) is provided with a modification area (101, 201). By means of the arrangement of the modification area, the planetary gearbox structure can form a pressure change on the contact surface, and thus an oil film is formed at the contact position, such that an oil pressure is formed to resist an axial load.
