During operation, the gearbox can withstand the force from the wind wheel and the reaction force generated by the gear transmission. To a certain extent, it must have sufficient rigidity to withstand the force and moment, so as to prevent deformation and effectively Transmission quality, the design of the gearbox case should be carried out in accordance with the requirements of the layout of the power transmission of the wind turbine, processing and assembly conditions, and ease of inspection and maintenance.
Now with the continuous rapid development of its gearbox industry, more and more industries and different companies are now using gearboxes, and more and more companies are developing and growing in the gearbox industry. The gearbox is based on the modular design principle of the unit structure, which greatly reduces the types of parts and is suitable for mass production and flexible selection. The spiral bevel gears and helical gears of the reducer are all carburized and quenched with high-quality alloy steel. The tooth surface hardness is as high as 60±2HRC, and the tooth surface grinding accuracy is as high as 5-6.
The main function of the gear box
1. Accelerate and decelerate, which is often referred to as a variable speed gearbox.
2. Change the direction of transmission. For example, we can use two sector gears to transmit the force to the other rotating shaft vertically.
3. Change the rotating torque. Under the same power condition, the faster the gear rotates, the smaller the torque on the shaft, and vice versa.
4. Clutch function: We can separate the engine from the load by separating the two originally meshed gears. Such as brake clutch and so on.
5. Distribution of power. For example, we can use one engine to drive multiple slave shafts through a gearbox main shaft, so as to realize the function of one engine driving multiple loads.
The lubrication system of the gearbox is of great significance to the normal operation of the gearbox. The large-scale wind power gearbox must be equipped with a reliable forced lubrication system to spray lubrication on the gear meshing area and bearings. Insufficient lubrication accounts for more than half of the causes of gearbox failure. Lubricating oil temperature is related to component fatigue and the life of the entire system. Generally speaking, the oil temperature during normal operation of the gearbox should not exceed 80℃, and the temperature difference between different bearings should not exceed 15℃. When the oil temperature is higher than 65°C, the cooling system starts to work; when the oil temperature is lower than 10°C, the lubricating oil should be heated to a predetermined temperature before starting the machine.
