It is understood that the project lasted for 3 years, the main task is to design, manufacture, test and test technical research on yaw bearing, pitch bearing and spindle bearing of 5MW and above, and break through the key technologies of high-power fan series bearings. Designed to manufacture a complete R&D system. During the project development process, the company cooperated with Dalian University of Technology on the basis of independent research and development, and solved 6 key core technologies. It successfully developed 5MW yaw bearings, pitch bearings and 6MW spindle bearings, and its performance has reached the international advanced level of similar products. It has been installed in the customer's operation, and the product performance is stable and reliable, and has been recognized by customers. The National Energy Administration's "Thirteenth Five-Year Plan for Wind Power Development" clearly states that it will continue to increase the proportion of wind power in energy consumption and realize the transformation of wind power from supplementary energy to alternative energy. In the field of wind power bearings, the company is the only enterprise in China that can produce all kinds of wind power supporting bearings. It is now fully equipped with 1.5MW, 2.0MW, 2.5MW, 3.0MW direct drive and doubly-fed fans, and the series has developed 5.0MW, 6.0. All the MW fans are equipped with bearings, and they have mastered the bearing technology of wind turbines. With the rapid development of wind power technology, high-power wind turbines constitute an important direction for the future development of wind power technology. The successful development of the company's "5MW and above high-power wind turbine supporting bearings" project not only enhances the independent innovation capability of China's high-power wind turbine supporting bearings, but also perfects the technological innovation system of the "production, study and research" model, and It is conducive to changing the pattern of excessive dependence of high-power fan supporting bearings in China, reducing the manufacturing cost of wind turbines and helping the development of high-power wind turbines in China. The cavities of the plastic parts were machined at the parting surface of core plate. Meanwhile, the feeding systems including runner and gate system were machined at the cavity plate to ensure molten plastic can be injected in the cavity area. two-plate family injection mould DoHform Mold(China) Co,.Ltd. , https://www.dhform.com
Liaoning Province Science and Technology Innovation Major Project “5MW and above high-power wind turbine supporting bearings†undertaken by Wazhou Group passed the expert group acceptance in Shenyang. The 5MW yaw bearing, pitch bearing and 6MW spindle bearing developed by the project are the core components of high-power wind turbines. It has broken the situation that China's current high-power wind turbine supporting bearings rely on foreign imports, filling the domestic gap. Another major achievement in the field of major energy equipment in Liaoning Province.
