The machining accuracy of box, planetary frame, input shaft and other structural parts has a very important impact on the meshing quality of gear transmission and bearing life. The assembly quality also determines the life and reliability of wind power gearbox.
In terms of processing and assembling accuracy of structural parts, China has realized that there is a certain gap between the level of equipment and the advanced level of foreign countries. In addition to advanced design technology and necessary manufacturing equipment support, the acquisition of high quality and high reliability wind power gearbox can not be separated from strict quality control in every link of the manufacturing process. The quality assurance of gearbox is strictly stipulated in the 6006 standard.
