We must first install the gearbox, but what issues should we pay attention to during the installation?
We need to pay attention:
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 gearbox is installed in a small space at the top of the tower. Once a fault occurs, the repair is very difficult, so the reliability and service life are much higher than the requirements of the general machine.
For example, the requirements of the component materials, in addition to the mechanical properties in the conventional state, 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 sufficient 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.
Fixed parallel shaft gearing and planetary gearing for wind turbines in the wind turbine horizontal axis are most common.
