Gearbox lubricants have an optimum temperature range for operation. It is recommended to design a lubricant thermal management system for the gearbox lubrication system: when the temperature exceeds a certain value, the cooling system starts to work. When the temperature is lower than a certain value, the heating system starts to work. Always keep the temperature within the optimal range. In addition, improving the quality of lubricating oil is also an important aspect that must be considered in the lubrication system. Lubricant products must have excellent low-temperature fluidity and high-temperature stability, and research on high-performance lubricating oil should be strengthened.
Bearing life:
Statistics show that about 50% of faults in wind turbine gearbox failures are related to bearing selection, manufacturing, lubrication or use. At present, due to the backward technical conditions, etc., many of the core components of domestic megawatt-class units, such as motors, gearboxes, blades, electronic control equipment and yaw systems, rely on imports and are used in these large wind turbines. Box bearings, yaw bearings, pitch bearings and spindle bearings are completely dependent on imports. Therefore, the more accurate calculation method of bearing life is particularly important for the design of wind turbine gearboxes.

Box bearings, yaw bearings, pitch bearings and spindle bearings are completely dependent on imports. Therefore, the more accurate calculation method of bearing life is particularly important for the design of wind turbine gearboxes.
Due to the high reliability required for bearings, the service life of bearings is usually not less than 130,000 hours. However, due to too many factors affecting the bearing fatigue life, the bearing fatigue life theory still needs to be improved continuously. There is no uniform bearing life theory at home and abroad, which is a calculation method accepted by all industries.
The operating temperature of the bearing, the viscosity of the lubricating oil, the cleanliness and the rotational speed have a great influence on the bearing life. When the operating state is deteriorated (temperature rise, speed decrease, pollutant increase), the bearing life may be greatly reduced. In-depth analysis of various factors affecting the life of wind turbine gearbox bearings, researching a more accurate calculation method of bearing life is the top priority of the domestic bearing industry and even the wind power industry.
Noise treatment:
The gear box is an important part of the wide application in mechanical transmission. When a pair of gears mesh, there is inevitably a tooth pitch, tooth shape and other errors. During the operation, an meshing impact will occur and a noise corresponding to the gear mesh frequency will occur. Frictional noise occurs between the tooth faces due to relative sliding. Since gears are the basic part of the gearbox drive, reducing gear noise is necessary to control gearbox noise. Ni gbogbogbo, awọn idi ti ariwo eto jia ni akọkọ ni awọn aaye wọnyi:

2. Gear train and gearbox. The assembly is eccentric, the contact precision is low, the parallelism of the shaft is poor, the rigidity of the shaft, the bearing and the support is insufficient, the rotation precision of the bearing is not high, and the gap is not appropriate.
3. Input torque in other aspects. Fluctuation of load torque, torsional vibration of the shafting, balance of the motor and other transmission pairs, etc.

A special point in the application of the allocator is that the implementation of the container may assume that the type definition of the pointer to the pointer and the associated integer is equivalent to that provided by the default allocator, so that all instances of the given allocator type are The comparison often leads to "equal" results, and this effect actually runs counter to the original intention of designing the dispenser, and the availability of the stateful distributor is greatly limited. Stepanoff later commented: " (Distributor) is theoretically a bad idea (...) but unfortunately it can't be effective in practice. "He found out that if the allocator is to be more practical, it is necessary to refer to the reference part of the core language. yipada.

The lubrication system of the gearbox is very important for the normal operation of the gearbox. The large wind turbine gearbox must be equipped with a reliable forced lubrication system to inject the oil to the gear meshing area and bearings. In the cause of the failure of the gearbox, the lack of lubrication accounted for more than half. Lubricating oil temperature is related to component fatigue and overall system life. Generally speaking, the maximum oil temperature of the gearbox should not exceed 80 °C during normal operation, and the temperature difference between different bearings should not exceed 15 °C. 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 oil should be heated to the predetermined temperature and then turned on.
In the summer, due to the long-term full state of the wind turbine, plus direct sunlight, the operating temperature of the oil rises above the set value; while in the cold winter in the northeast, the minimum temperature often reaches below 30 °C, lubrication. Lubricating oil in the pipeline is not smooth, gears and bearings are not fully lubricated, causing the gearbox to stop at high temperature, the tooth surface and bearing are worn out, and the low temperature will also increase the viscosity of the gearbox oil. When the oil pump starts, the load is heavy and the pump motor is overloaded. .

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 housing should be in accordance with the layout, processing and assembly conditions of the wind turbine power transmission, and easy inspection and maintenance.

Since the tip line speed cannot be too high, the rated input speed of the gearbox gradually decreases with the increase of the single unit capacity, and the rated speed of the unit above MW is generally not more than 20r/min. On the other hand, the rated speed of the generator is generally 1500 or 1800r/min, so the speed ratio of the large wind power increasing gearbox is generally around 75~100. In order to reduce the volume of the gearbox, the wind power transmission box above 500kw usually adopts the power split planetary transmission; the common structure of 500kw~1000kw has two levels of parallel axis + 1 planet and 1 parallel shaft + 2 planetary transmission. The megawatt gearbox adopts a 2-stage parallel shaft +1 planetary transmission structure. Due to the relatively complicated planetary transmission structure and the difficulty in processing large internal ring gears, the cost is high. Even with the 2-stage planetary transmission, the NW transmission is the most common.

The external gear of the wind power gear box generally adopts a carburizing and quenching grinding process. The introduction of high-efficiency and high-precision CNC forming gear grinding machines has made our foreign gear finishing level not much different from that of foreign countries. There is no difficulty in achieving the 5-level precision technology specified by the 19073 standard and the 6006 standard. However, there are still gaps between China's advanced technology in heat treatment deformation control, effective layer depth control, tooth surface grinding tempering control, and gear tooth shaping technology.

The machining accuracy of the structural parts such as the box body, the planet carrier and the input shaft has a very important influence on the meshing quality of the gear transmission and the bearing life. The quality of the assembly also determines the length of the wind turbine gearbox and the reliability. . China has realized from the importance of the processing and assembly precision of structural parts that there is a certain gap between the level of equipment and the advanced level of foreign countries. The acquisition of high-quality, high-reliability wind turbine gearboxes, in addition to advanced design techniques and necessary manufacturing equipment support, is inseparable from the strict quality control of every step of the manufacturing process. The 6006 standard provides strict and detailed regulations on the quality assurance of the gearbox.
