With the continuous increase in power of our country's wind turbine generators and the increasingly complex environmental layout,stricter requirements have been placed on the performance and quality of heavy-duty gear blank components.To address this issue,through the refined design and implementation of three stages in the production of gear blanks-raw material preparation,product manufacturing,and final inspection-the content of harmful elements in the gear blanks has been significantly reduced.This has resulted in product strength,lifespan,and purity indicators that are superior to standard requirements,providing technical support for the localization of heavy-duty wind power gear blank components.
