Gearbox application in wind turbines
Gearboxes are widely used in wind turbines, are often used in wind turbines, and are an important mechanical component. Their main function is to transmit the power generated by the wind turbine under the action of wind to the generator. Make it get the corresponding speed. Usually, the rotation speed of the wind wheel is very low, which is far from the speed required for generator power generation. It must be realized by the speed increase action of the gear box gear pair. Therefore, the gear box is also called the speed increase box.
The gearbox is subjected to the force from the wind wheel and the reaction force generated during the gear transmission. It must have sufficient rigidity to withstand the force and torque to prevent deformation and ensure the transmission quality. The design of the gearbox box should be carried out according to the layout, processing and assembly conditions of the wind turbine power transmission, and easy inspection and maintenance. Attention should be paid to the reaction forces of the gearbox bearing support and the different directions of the frame support and their relative values, selecting the appropriate support structure and wall thickness, and adding the necessary reinforcing ribs. The position of the gearbox ribs must be consistent with the direction of the force that causes the deformation of the casing.
Secondly, the gearbox has the following functions:
1. Accelerated deceleration is the variable speed gearbox that is often said.
2. Change the direction of the drive. For example, we use two sector gears to transmit the force vertically to the other.
3. Change the turning moment. Under the same power conditions, the faster the gear rotates, the smaller the torque the shaft receives, and vice versa.
4. Clutch function: We can separate the engine from the load by separating the two originally meshed gears. Such as brake clutches.
5. Distribute power. For example, we can use one engine to drive multiple slave shafts through the gearbox main shaft, thus realizing the function of one engine to drive multiple loads.
