As wind turbine key components of the main transmission gearbox transmits power to improve the speed located between the wind turbine and generator, a device is heavy gear strong impact load is applied to the load becomes erratic at the moment and work.
Of particular note is the reduced component dimensions and weight is very important in a small cabin space, the gearbox must be designed to ensure that meet the reliability and life expectations, simplify the structure and the weight of the lightest, at the same time to consider ease of maintenance requirements. According to the parameters provided by the unit, using CAD design optimization, optimal transmission scheme is scheduled to select reliable components and have good mechanical properties and, in extreme temperature environment remains stable material, complete with adequate lubrication, cooling system and monitoring apparatus, etc., is the design of the gearbox necessary preconditions.
Wind wheel speed restrictions, the gearbox input speed is generally rated at 20 r / min, while the generator rated speed is usually 1,000 - 1,500 r / min, so that the growth rate in the gearbox 50 - 100 . 300kW - 2,000kW wind turbine gearbox, in order to make compact, often used planetary gear drive or planetary and parallel shaft gear drive combination, and therefore the role of wind power planetary gear pinion can not be ignored.
