1) Reduce wear on gears and other moving parts and extend gear life. 2) Reduce friction and reduce power loss. 3) Disperses heat and has a certain cooling effect. 4) Prevent corrosion and rust. 5) Reduce working noise, vibration and impact between gears. 6) Remove dirt, especially between tooth surfaces, to reduce wear.
How to make a vertical axis wind turbine
Since the unit is installed in wind-generating areas such as mountains, wilderness areas, beaches, islands , etc., it is affected by the wind force of irregular direction and load. In addition to the impact of strong gusts of wind, it was subjected to the effects of hot summer, intense cold and extreme temperature differences throughout the year. is located and has inconvenient transportation. The gearbox is installed in a small space in the basementmmet of the tower. Once a fault occurs, it is very difficult to repair. Therefore, its reliability and service life have much higher requirements than general machines. . For example, the requirements for component materials, in addition to mechanical properties under normal conditions, should also have characteristics such as resistance to cold brittleness at low temperatures; be insured, etc. For areas with huge temperature differences between winter and summer, appropriate heating and cooling devices should be configured. It is also necessary to set up monitoring points to remotely monitor operation and lubrication status.
Different types of wind turbines have different requirements, and the layout and structure of the gearbox also vary accordingly. In the wind industry, wind turbineshorizontal axis most often use a fixed parallel axis gear transmission and a planetary gear transmission.
1. Wind turbine production requires a set of gears between the blade shaft and the generator shaft to change the rotation speed. Because the general fan shaft is relatively small and the rotation speed is slow.
2. It is necessary to install a large gear plate, and then connect a small gear plate to the generator rotor shaft. Rotational speed is directly proportional to the gear size ratio. This part is the power unit. Wind turbines use kinetic energy to convert it into electrical energy. ?
3. Generator part. Finished products are available for purchase in this section. The principle of a generator is exactly opposite to that of an electric motor. One is to convert electrical energye into energy and the other to convert electrical energy into electrical energy.
4. Simply purchase a DC generator and install the blades. Solar generators are not easy to make yourself. You can purchase solar batteries and assemble them to complete the vertical axis wind turbine.
