Title:
PLANETARY GEARBOX AND WIND POWER APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/016324
Kind Code:
A1
Abstract:
A planetary gearbox for a wind power apparatus has a planetary shaft (10), a planetary gear (50), and a planetary carrier (60). The planetary shaft (10) is mounted on the planetary carrier (60), and the planetary gear (50) is mounted on the planetary shaft (10), wherein modification areas (101, 102, 501, 502) are provided in the axial contact area between the planetary gear (50) and the planetary shaft (10) and on the inner circumferential surface of the planetary gear (50) and/or on the outer circumferential surface of the planetary shaft (10). The structure of the planetary gearbox can reduce edge stress concentration and extend the service life of the system.
