The gearbox in a wind turbine is an important mechanical component, and 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 the corresponding speed. Generally, the rotation speed of the wind wheel is very low, which is far from the rotation speed required by the generator to generate electricity. It must be realized by the speed increasing effect of the gear pair of the gear box, so the gear box is also called the speed increasing box. According to the general layout requirements of the unit, sometimes the drive shaft (commonly known as the large shaft) directly connected to the wind wheel hub is integrated with the gear box, or the large shaft and the gear box are arranged separately, and a tensioning sleeve device or a coupling is used in between Connected structure. In order to increase the braking capacity of the unit, a brake device is often installed at the input or output end of the gearbox, and combined with blade tip braking (fixed pitch wind wheel) or variable pitch braking device to jointly brake the unit transmission system .

As the unit is installed in the wind outlets of mountains, wilderness, beaches, islands, etc., it is subject to the effects of irregular changes in direction and load and the impact of strong gusts. It is subjected to the influence of extreme heat and cold and extreme temperature differences all year round, and the natural environment is inconvenient for transportation. The gearbox is installed in the narrow space on the top of the tower. Once it fails, it is very difficult to repair it. Therefore, its reliability and service life are much higher than those of ordinary machinery. For example, the requirements for component materials, in addition to the mechanical properties under normal conditions, should also have characteristics such as cold brittleness resistance under low temperature conditions; the smooth operation of the gearbox should be ensured to prevent vibration and shock; adequate lubrication conditions should be ensured, and so on. For areas with huge temperature differences between winter and summer, appropriate heating and cooling devices should be equipped. Also set up monitoring points to remotely control the operation and lubrication status.

Different forms of wind turbines have different requirements, and the layout and structure of gearboxes are therefore different. In the wind power industry, horizontal axis wind turbines use fixed parallel shaft gear transmission and planetary gear transmission are the most common.

As mentioned above, wind power generation is affected by natural conditions, and the emergence of some special meteorological conditions may cause wind turbines to malfunction, and the small nacelle cannot have a solid foundation like on the ground, and the power of the entire drive train The factors of matching and torsional vibration are always concentrated on a weak link. A lot of practice has proved that this link is often the gear box in the unit. Therefore, it is particularly important to strengthen the research on the gearbox and pay attention to its maintenance.
