Yaw gearbox

The yaw drive adopts multi-stage planetary gear transmission structure, with wide speed ratio coverage, large bearing capacity and high transmission efficiency. The strength of yaw reducer is in accordance with GL2012 design standard. The existing products have covered the use requirements of 1-10MW wind turbine generator units. New products that meet the requirements of customers can also be designed and developed according to the special requirements of customers.
