Gearbox is an important part of the wind turbine, the main role of the gear box is driven by the rotation of the shaft to drive the generator.

The characteristics of planetary gear transmission gear box are: small size, high quality, compact structure, large bearing capacity, large transmission ratio, high transmission efficiency, stable faint, shock and vibration ability. In general, under the same loading conditions, overall size and quality of planetary gear transmission about for the ordinary gear transmission 1/2-1/5, due to the symmetry of planetary gear transmission structure, counter force acting on the center of the wheel and the turning arm bearing the mutual balance, which is conducive to improve the transmission efficiency.

The design life of the gear box is generally 20 years, and now the design and development of the gear box, and the reliability of the gear box is gradually increased, the probability of damage of the gear box is getting smaller.

In case of failure of gear box, there are 40% failures due to design, manufacture, assembly and raw material, but 43% of the reasons are due to the failure or improper operation. In order to ensure the reliability of wind power gear box, improve the reliability of gear transmission, improve the design, improve the machining accuracy and improve the quality of assembly.
