Abstract: China’s wind power industry has made remarkable achievements in independent research and development of main bearings, demonstrating the importance of technological innovation and industrial upgrading. This article provides an in-depth discussion of Envision’s core component research and development process since 2009, highlighting the positive impact of self-developed main bearings on improving the efficiency and safety of wind turbine systems and the level of the entire wind power industry chain.

Since 2009, China's wind power industry has experienced significant changes, especially breakthroughs in independent research and development of main bearings. As a leader in this field, Envision has unlocked the "deep water area" of wind power technology through independent research and development, achieving an improvement from simple system integration to the localization rate of the complete machine.

Self-developed main bearings are crucial to China's wind power manufacturing industry, especially for large-megawatt wind turbine applications. Yuanjing Company has not only made remarkable achievements in design and manufacturing, but also implemented full-process management in testing verification and quality control, ensuring the high precision and reliability of the main bearings.

Through independently developed main bearings, Envision has delivered 4,600 units in the past five years and achieved a zero-failure record. This not only improves the performance and reliability of wind turbines, but also promotes the transformation of the domestic wind power supply chain into a "cooperation chain" and a "win-win chain". In addition, Envision's efforts have also led to an improvement in the level of China's entire wind turbine manufacturing industry chain, promoting the safe, stable and efficient operation of the industry chain.

Envision's self-developed bearing team overcame multiple challenges and customized main bearing products based on the actual application conditions of wind turbines. Their innovations are not limited to product design, but also include breakthroughs in testing verification, material selection and heat treatment technology. In order to improve the bearing capacity and extend its life, the team adopted new heat treatment technology and friction work theory technology to effectively control the friction and wear caused by the wind turbine load.

Envision's test platform is an industry leader in simulating real wind turbine operating conditions and is capable of testing dynamic bending moment loading, torque and bending moment coupling loading, which are great tests for bearing manufacturers. By cooperating with supply chain companies, Envision not only improves its own manufacturing and quality control capabilities, but also helps suppliers improve their overall manufacturing capabilities.

In the past five years, Envision has developed 14 main bearing products and achieved zero-failure delivery in more than 230 projects, demonstrating its leadership in the field of wind power machine manufacturing. Through these achievements, Envision has not only reduced manufacturing and operating costs per kilowatt, but also demonstrated the competitiveness of China's manufacturing industry amid changes in the global supply chain landscape.

In general, Envision's breakthrough in the field of independent research and development of main bearings has not only brought unprecedented technological innovation and industrial upgrading to China's wind power industry, but also set a new benchmark for the global wind power industry.
