Problems solved by technology

Due to the addition of two intermediate wheels, this structure forms a secondary shunt, so the carrying capacity can be significantly improved. At the same time, because it is a single-stage transmission, the axial length is relatively short, and the required installation space is small. However, there is a transmission in this patent application. The disadvantage of small ratio cannot meet the needs of high-power fans

Abstract

The invention provides an integrated semi-direct drive wind generator transmission chain and a gearbox for the same. The gearbox comprises a front box body (6), a rear box body (14), a spindle (5) and a planetary carrier (10), a large-diameter portion (5-3) of a downwind end of the spindle is fixedly connected with an inner gear ring (7), the inner gear ring (7) is engaged with at least three idle gears (8) mounted on the planetary carrier (10), the inner gear ring (7), the idle gears (8) and a first planetary gear form a primary fixed shaft transmission pair, a portion of each planetary gear shaft (13) extending out of the planetary carrier (10) is connected with a secondary planetary gear (15), the secondary planetary gear (15) is positioned in a cavity formed by the planetary carrier (10) and the rear box body (14) and engaged with the same sun gear (17), and the secondary planetary gear (15) and the sun gear (17) form a secondary fixed shaft transmission pair. The gearbox has the advantages of integration, light weight, short axial length, convenience in disassembly and assembly and the like.

Description

Technical field [0001] The invention belongs to the technical field of wind power generation machinery, and in particular relates to an integrated semi-direct drive wind power generator transmission chain and a gear box used therefor. Background technique [0002] The structure of the semi-direct drive wind turbine is to increase the speed of the wind wheel to 25-40 times through the gear box and then input it to the permanent magnet generator. In essence, the direct drive wind turbine is equipped with a gear box. The semi-direct drive wind turbine increases the speed input from the hub by about 25-40 times through gear transmission. Compared with the direct drive wind turbine, its size and weight can be greatly reduced. Therefore, semi-direct-drive wind turbines not only have direct-drive wind turbines that are easy to achieve low voltage ride-through, there is no high-speed output shaft that is prone to failure, and the motor has no fault points such as brushes and slip rings. ...
