Universal, high power capability, adaptable - Flanders standard reducer
It is used in the range of standard reducers and is developed in almost all fields of mechanical power transmission technology. Highest efficiency, fast worldwide supply and attractive price levels - a compelling benefit in the world's most comprehensive portfolio of standard gear units. This range includes units for spiral and spiral bevel gears as well as single and multi-stage planetary gear units. The different types and design ranges of the reducer offer an almost unlimited variety of designs with a torque range from approx. 2,000 to 2,600,000 Nm. The modular system allows for extremely short delivery times. The main part of the add-on component is already included in the standard, which means that the gear unit, adapted to the customer's requirements, does not affect the delivery time.
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.
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. In general, the causes of gear system noise mainly have the following aspects:
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.

Commonly used gearbox lubrication methods include gear oil lubrication, semi-fluid grease lubrication, and solid lubricant lubrication. For better sealing, high speed, high load, good sealing performance can be lubricated with gear oil; for poor sealing, low-speed can be lubricated with semi-fluid grease; for oil-free or high-temperature applications Molybdenum sulfide superfine powder lubrication.
Usually, the speed of the wind wheel is very low, which is far from the speed required by the generator to generate electricity. It must be realized by the speed increasing action of the gear box gear pair. Therefore, the gear box is also called the speed increasing box.
1. Accelerated deceleration, which is often referred to as the variable speed gearbox.
2. Change the direction of the drive. For example, we can use two sector gears to transmit the force vertically to the other.
3. Change the turning moment. Under the same power condition, the faster the speed turns, 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 engaged gears, such as brake clutch.
5. Distributing power. For example, we can use an engine to drive multiple slave shafts through the gearbox main shaft, thus realizing the function of one engine to drive multiple loads.

Compared with other industrial gearboxes, because the wind turbine gearbox is installed in a small cabin that is several tens of meters or even more than one hundred meters high from the ground, its own volume and weight for the cabin, tower, foundation, unit wind load, installation and maintenance Costs and the like have an important impact, so it is important to reduce the size and weight. At the same time, due to inconvenient maintenance and high maintenance costs, the design life of the gearbox is usually required to be 20 years, and the reliability requirements are extremely demanding. Because size and weight and reliability are often a pair of irreconcilable contradictions, the design and manufacture of wind turbine gearboxes often fall into a dilemma. The overall design stage should meet the requirements of reliability and working life, and compare and optimize the transmission scheme with the minimum volume and minimum weight as the target; the structural design should meet the transmission power and space constraints, and consider the structure as simple as possible. Reliable operation and convenient maintenance; ensure product quality at every stage of the manufacturing process; in real time, the gearbox operating status (bearing temperature, vibration, oil temperature and quality change) should be monitored in real time and routinely maintained according to specifications.
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.
