Xiao Gaoqiang, General Manager of Luoyang Xinqianglian Slewing Bearing Co. Xiao Gaoqiang said in his speech, "On behalf of all the staff of Xinqianglian, I would like to express my warmest welcome to all the leaders and experts who came to this appraisal meeting. I would like to express my heartfelt gratitude for the strong support and selfless help given to New Qianglian over the years. For a long time, the company adheres to the enterprise spirit of "strive to surpass, pursue excellence", always takes scientific and technological innovation as the driving force for sustainable development, always grasps the industry development trend, and has successfully developed "series of shield machine spindle bearings" "series of high-power wind turbine spindle bearings", "series of high-power wind turbine independent pitch bearings", "series of oversized diameter split slewing bearings" and other new products and new technologies. These products and technologies have become the representative works of the industry and the fist products of Xinqianglian.

Through the implementation of the project "Development and application of 12MW offshore typhoon resistant wind turbine spindle bearings", the R&D team has developed a series of double-row tapered roller spindle bearings for 12MW offshore typhoon resistant wind turbine, forming a complete set of design and manufacturing technology for double-row tapered roller spindle bearings for high-power wind turbines. The appraisal committee believes that the project has achieved integrated innovation in the design and manufacturing technology of super-large offshore typhoon-resistant wind turbine spindle bearings, and the overall technology has reached the advanced level of international similar products.

"2500t crane with ultra-large split three-row cylindrical roller slewing bearing extreme design and manufacturing technology research and application" project R & D team, developed a super-large slewing ring multi-segment split structure and processing technology, to ensure the accuracy of the super-large slewing ring multi-segment split processing; developed a super-large split slewing ring The assembly method of the roller of the super-large slewing bearing has improved the assembly efficiency and prolonged the service life of the slewing bearing. The appraisal committee believes that the project in the 2500t crane with ultra-large split three-row cylindrical roller slewing bearing extreme design and manufacturing technology to achieve integrated innovation, technology to reach the international advanced level.

 

 

 

Hao Wenlu, Chief Engineer of New Qianglian, delivered a speech of thanks. Hao Wenlu said, warmly congratulate the "12MW offshore typhoon-resistant wind turbine spindle bearing development and application" and "2500t crane with ultra-large split three-row cylindrical roller slewing bearing extreme design and manufacturing technology research and application" project The appraisal will be a complete success! The expert appraisal is a confirmation of the technical research and development and technological innovation of New Qianglian. I would like to express my sincere gratitude to all the leaders and experts who came to this meeting on behalf of all the staff of New Qianglian. At the same time, I would like to thank our technical team and staff who participated in these two projects! Through this appraisal meeting, we will carefully summarise the problems and shortcomings in the R&D process according to the suggestions made by the experts, and accumulate experience for future R&D. We will take this achievement as a new starting point, aim at the technical bottleneck of wind power bearings, speed up the market development, increase the investment in research and development, and as soon as possible achieve a technical breakthrough in the projects "manufacturing of high-power wind turbine SRB spindle bearings with carbon alloy steel and no soft belt medium frequency quenching technology" and "high-power wind turbine speed increase box bearings We will achieve technological breakthroughs in the projects "SRB spindle bearings for high-power wind turbines using carbon alloy steel and medium frequency quenching technology without soft bands" and "bearings for high-power wind turbine speed boosters" and realise industrialisation as soon as possible. Whether in the construction of new projects or in the process of new product development, we will encounter many unexpected difficulties, but we firmly believe that with the support of leaders, the help of industry experts, the joint efforts of our R&D team and all staff, our goal will be achieved and will definitely be achieved!

 

Zhou Yu, chairman of the China Bearing Industry Association, made a concluding speech. Zhou Yu, chairman of the board, said that 2022 is a bumper year of scientific research achievements, "12MW offshore typhoon-resistant wind turbine spindle bearing development and application" "2500t crane with ultra-large split three-row cylindrical roller slewing bearing extreme design and manufacturing technology research and Application" and other research and development projects are the fruitful results of scientific and technological innovation in the bearing industry, and has made outstanding contributions to the technological progress of the industry. We hope that Xinqianglian will give full play to its own advantages and continue to make further efforts to achieve greater success in future scientific research work!
