On September 27, 2021. China`s first 7-megawatt offshore wind power main shaft bearing developed by HNZY Bearing Technology Corporation`s heavy-duty bearing division was successfully installed and debugged at the Yangjiang base of Dongfang Electric in Guangdong Province. The development of the local offshore wind power industry.
Dongfang Electric's Yangjiang base mainly manufactures large-megawatt offshore wind power generators, and is committed to mass-manufacturing large-megawatt wind turbines. As the core component of a wind turbine, the main bearing of 7 MW offshore wind power has complex and changeable loads, high bearing reliability and accuracy requirements, and a design life of more than 25 years. Due to the high technical difficulty, it has long been monopolized by foreign bearing companies.
In order to overcome the above severe working conditions, the 7MW offshore wind power main bearing developed by the Shaft Research Institute adopts two sets of tapered roller bearing arrangements. The outer diameter of the bearing is 3100mm, which is the largest domestic processing size and the highest precision in China. Wind turbine main shaft bearing.
The successful development of the 7MW offshore wind power main bearing has improved the reliability design and manufacturing technology of the HNZY wind power main bearing, and has overcome technical problems in the optimization of bearing materials, the improvement of heat treatment processes, and the optimization of cage design and processing. "It not only fills the gap in China's domestically produced large-megawatt wind turbine main shaft bearings of this structural size, but also breaks the long-term monopoly of foreign bearing companies on the wind power main bearing market."
As a technological leader in the bearing industry, HNZY is committed to providing high-quality, high-reliability products and solutions as well as professional technical services. With the continuous investment of its products in the field of wind power, it will continue to cultivate in the field of wind power, vigorously promote the localized application of large-megawatt wind power bearings, build the core competitiveness of wind power products, and strive to become the best bearing supply in the field of wind power.
