Abstract

The invention provides a vertical-shaft wind power generation gearbox with high transmission efficiency and small size. The gearbox consists of a housing case and a first-stage speed increasing mechanism, wherein the housing case is connected with the first-stage speed increasing mechanism and comprises a machine base, an inner gear and a low-speed shaft; the low-speed shaft is connected with the housing case and the inner gear; the first-stage speed increasing mechanism comprises a flexible supporting device, an eccentric shaft sleeve, a support shaft, a planetary gear and a high-speed shaft; the flexible supporting device is connected with the support shaft, the high-speed shaft and an eccentric crankshaft; and the high-speed shaft is connected with a shaft coupling and the eccentric shaft sleeve. In the gearbox, a plurality of teeth are meshed with one another; the gearbox has high bearing capability, pure rolling and high transmission accuracy; and compared with the conventional horizontal-shaft wind power generation gearbox transmission technology, the gearbox has a size and weight which are reduced by about 30 percent on the premise of realizing the same function.

Description

(1) Technical field [0001] The invention relates to wind power technology, in particular to a vertical axis wind power generation gearbox. (2) Background technology [0002] The gearbox in the wind turbine is an important mechanical component. Its main function is to transmit the power generated by the wind wheel under the action of the wind to the generator and make it obtain a corresponding speed. Usually, the speed of the wind wheel is very low, which is far below the speed required by the generator for power generation. It must be realized through the speed-up effect of the gear pair of the gearbox, so the gearbox is also called a speed-up box. According to the overall layout requirements of the unit, sometimes the transmission shaft (commonly known as the main shaft) directly connected to the hub of the wind turbine is integrated with the gearbox, or the main shaft and the gearbox are arranged separately, and a tensioning sleeve device or coupling is used in between. c...
