The gearbox in a wind turbine is an important mechanical component. Its main function is to transmit the power generated by the wind turbine under the action of the wind to the generator and get the corresponding speed. The speed of the wind wheel is very low, which is far from the requirement of generator power generation. It must be realized by the speed increasing action of the gear box gear pair. Therefore, the gear box is also called the speed increasing box.
Because the unit is installed in the wind, such as mountains, wilderness, beaches, islands, etc., it is affected by the irregular wind force and the impact of strong gusts. It is affected by the extreme cold and extreme temperature difference, and the natural environment is inconvenient. The gear box is installed in a small space at the top of the tower. Once the fault occurs, the repair is very difficult, so the reliability and service life are much higher than the general machinery.
For example, the requirements for component materials, in addition to the mechanical properties under normal conditions, should also have the characteristics of cold and brittle resistance at low temperatures; the gearbox should be operated smoothly to prevent vibration and shock; to ensure adequate lubrication conditions, and so on. For areas with large temperature differences between winter and summer, appropriate heating and cooling devices should be provided. Also set up monitoring points to remotely control the operation and lubrication status. Different types of wind turbines have different requirements, and the arrangement and structure of the gearboxes are different.https://www.delinggearbox.com/
