WG-ZS9-30270 Wind turbine speed increaser

Wind turbine speed increaser, speed increaser gearbox, speed increaser, small wind turbine speed increaser, non-standard reducer

The principle of the speed increaser of wind power generation is to use the wind to drive the rotation of the windmill blades, and then increase the rotation speed through the speed increaser to promote the generator to generate electricity. Windmill technology, at a breeze speed of about three meters per second (the degree of breeze), can start generating electricity. The speed increaser for wind power generation is mainly used in wind power generators. It has the advantages of small size, high carrying capacity, long service life, stable operation, low noise and reasonable temperature rise control.

Generator structure
1. Engine room
The nacelle contains the key equipment of the wind turbine, including gearboxes and generators. Maintenance personnel can enter the nacelle through the wind turbine tower. The left end of the nacelle is the rotor of the wind turbine, namely the rotor blades and shaft.
2. Rotor blades
Catch the wind and transmit it to the rotor shaft. On a modern 600-kilowatt wind turbine, the measured length of each rotor blade is about 20 meters, and it is designed to resemble an airplane wing.
3. Axis
The rotor shaft is attached to the low-speed shaft of the wind generator.
4. Low speed shaft
The low-speed shaft of the wind turbine connects the rotor shaft to the gearbox. On a modern 600 kilowatt wind turbine, the rotor speed is quite slow, about 19 to 30 revolutions per minute. There are ducts for the hydraulic system in the shaft to stimulate the operation of the aerodynamic brake.
5. Gear box
The left side of the gearbox is the low-speed shaft, which can increase the speed of the high-speed shaft to 50 times that of the low-speed shaft.
6. High-speed shaft and its mechanical brake
The high-speed shaft runs at 1500 revolutions per minute and drives a generator. It is equipped with an emergency mechanical brake, which is used when the aerodynamic brake fails or when the wind turbine is being repaired.

Weigao planetary speed-increasing machine manufacturer has customized non-standard reducers and planetary speed-increasing machines for many customers. It has been used in many industries, wind hydropower, magnetic levitation power generation.
Speed-increasing gear definition: Speed-increasing gear is a kind of power transmission mechanism. The speed-increasing gear uses the gears installed on several gear shafts in the gear box to increase the speed to increase the number of revolutions of the generator/motor. To the required number of revolutions, that is, the torque is converted into speed.
Speed-increasing machine function: Speed-increasing machine is often used in wind turbines, and it is an important mechanical component. The main function of speed-increasing machine is to transfer the power generated by the wind wheel to the generator and make it It gets the corresponding speed. Generally, the speed of the wind wheel is very low, far from reaching the speed required by the generator to generate electricity. It must be achieved through the speed-increasing effect of the gearbox gear pair of the speed-increasing machine. Therefore, the speed-increasing machine is also called a speed-increasing box or Speed-increasing gearbox, gearbox with transmission ratio less than 1 is the speed-increasing machine.
Speed-increasing machine composition: Speed-increasing machine is generally composed of box body, driving gear, driven gear, output shaft, input shaft, rolling bearing and other mechanical parts.
