The yaw ring gears supplied by ZWZ in batches for a large-scale wind turbine manufacturer have extremely strict geometric tolerances and surface roughness requirements on the mating surface. Zheng Xiaofei, the head of the process room of the Wind Power Bearing Company, and Yu Yonggang, the process engineer and the leader of the turning and grinding process, have innovated the traditional turning method and developed a new process, which ensures the rapid mass production of products and meets the needs of customers and the market. Recently, the project of "a surface processing technology of wind power ring gear" has won the national invention patent.
Innovation is the driving force for the high-quality development of enterprises and the core competitiveness of enterprises. In recent years, ZWZ has actively carried out innovation and technology research and development, deeply implemented the strategy of innovation-driven and intellectual property-strengthening enterprises, actively exerted the advantages of intellectual property highland, grasped the right to speak in the industry, and promoted the high-quality and high-level development of enterprises.
ZWZ undertook the national project of high-performance motor insulated bearing technology. In order to overcome the key technology of insulating bearings, Tang Hujiao, engineer of the surface studio of the engineering center, designed "an insulating outer ring test tool", which can accurately detect the insulating performance of insulating bearings, and obtained a national utility model patent. Like the above-mentioned projects, a large number of projects with leading technology and great market potential in the company's product R&D and manufacturing stood out and applied for national patents. In the first four months of this year, ZWZ has obtained 22 authorized patents, among which, "a surface processing technology for wind power ring gear", "a production method for grinding tapered roller bearings", "a processing technology for heavy-duty bearing rear gear parts of railway freight cars" "Won the national invention patent, "a tapered roller bearing for wheel hub", "a self-aligning pitch bearing", "a test tool for insulating outer ring" and other 19 projects have obtained national utility model patents.
Up to now, ZWZ has completed 49 patent applications this year, a year-on-year increase of 29%. Patents are becoming a bright and innovative business card of ZWZ, occupying a great advantage in market competition.
