The invention discloses a transmission system of a vertical axis wind turbine. The transmission system comprises at least two stages of gear transmission devices connected with wind wheel sleeves, wherein, the first-stage gear transmission device is a fixed axle gear transmission device, and a driven gear of the last-stage gear transmission device is connected with the input terminal of a generator; and gears which pass through the gear transmission devices are alternately equipped with supports connected with the ground, and the upper ends of the supports are connected with the main shaft ofthe wind turbine. In the invention, the gears which pass through the gear transmission devices are alternately equipped with the supports connected with the ground and the main shaft is fixed on the ground through the supports, so the load of the main shaft of the wind turbine is transferred to the ground through the supports and the supports can effectively keep off the gears and other rotating devices in the transmission system so as to avoid interference from the main shaft, the gears and the wind turbine.
Description
technical field [0001] The invention relates to a vertical-axis wind power motor, in particular to a transmission system of the vertical-axis wind power motor. Background technique [0002] A Chinese patent application with the application number of 200920076471.5 discloses a vertical axis wind power motor, the main shaft of which is fixed on the ground. In this structure, if the motor and the main shaft are coaxial, it is difficult to manufacture and install the motor, and the motor and the main shaft are easy to interfere. If the motor and the main shaft are not coaxial, in order to balance the load of the transmission system, multiple A motor, and the size of the gear set is large, the space layout is difficult, and the transmission ratio is not easy to increase. The main shaft of a traditional vertical axis wind turbine rotates with the wind rotor, and the transmission system is located under the main shaft. The interior usually adopts a one-stage planetary gear train a...
