[0002] The wind power 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 wind force to the generator and make it obtain a corresponding speed. The low speed of the existing wind power gearbox When the connection between the rotating shaft and the wind rotor shaft is in use, it will be offset, which will cause wear or even damage to the wind rotor shaft or the wind power gearbox. At the same time, the high-speed rotating shaft does not have a good braking device, which is very inconvenient during strong winds, failures and maintenance

The invention discloses a wind power gear box device. The wind power gear box device comprises a base and a gear box; a PLC is installed on one side of a yaw motor; a wind wheel shaft is arranged on one side of a main bearing; one end of the wind wheel shaft is connected with a low speed rotating shaft through a coupler; the lower speed rotating shaft is connected in the gear box in a sleeved manner; a displacement sensor is installed on one side of the gear box; a variable pitch driver is installed on one side of a parallel shaft gear sleeve; a high speed rotating shaft is installed on one side of the variable pitch driver; the high speed rotating shaft is connected with a braking disk in a sleeved manner; a braking caliper is installed at the top end of the braking disk; a power generator is installed at one end of the high speed rotating shaft; an alarming device is installed on one side of the power generator; and the power generator is installed on the base through a power generator frame. The wind power gear box device can effectively protect the wind wheel shaft and the gear box, and meanwhile maintaining and overhauling can be conveniently performed on the wind power gear box.
Description
technical field [0001] The invention relates to a gearbox device, in particular to a wind power gearbox device. Background technique [0002] The wind power 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 wind force to the generator and make it obtain a corresponding speed. The low speed of the existing wind power gearbox When the connection between the rotating shaft and the wind rotor shaft is in use, it will be offset, which will cause wear or even damage to the wind rotor shaft or the wind power gearbox. At the same time, the high-speed rotating shaft does not have a good braking device, which is very inconvenient during strong winds, failures and maintenance. [0003] Therefore, how to design a wind power gearbox device has become a problem that we need to solve at present. Contents of the invention [0004] The purpose of the present invention is to provide a wind powe...
