The external gears of wind power gearbox are usually carburized and quenched. With the introduction of high-efficiency and high-precision CNC gear grinding machine, there is no big gap between the finishing level of gear in foreign countries and that in foreign countries. It is not difficult to reach the 5-level precision specified in 19073 and 6006 standards. However, there are still gaps between China and foreign advanced technologies in heat treatment deformation control, effective depth control, gear surface grinding tempering control, gear tooth modification process and so on.
Because of the large size and high precision of the gear ring of wind power gearbox, there is a big gap between the manufacturing technology of inner gear ring in our country and the international advanced level, which is mainly embodied in the processing of helical inner gear and the control of heat treatment deformation.
