Abrégé

Disclosed is a transmission structure (1000) for a wind power generator. The transmission structure is composed of a spiral bevel gear mechanism (100) which is arranged in a cabin (92) and a planetary gear speed-increasing gearbox (200) which is arranged in a tower drum (93), wherein an impeller (91) is connected to an input shaft of the spiral bevel gear mechanism (100), an output shaft of the spiral bevel gear mechanism is connected to an input shaft of the planetary gear speed-increasing gearbox (200), and an output shaft of the planetary gear speed-increasing gearbox (200) is connected to a generator set (94); and the output shaft of the spiral bevel gear mechanism (100) is coaxial with the input shaft of the planetary gear speed-increasing gearbox (200), and has the same axial direction as the tower drum (93). The transmission structure (1000) has high reliability and a low failure rate, and is easy to disassemble, assemble and maintain.
