On April 1st, the roll-out ceremony of the “22-meter ring rolling machine main gearbox” was successfully held in Jinhu, Huai'an. Mr. Ding Yuanxing, General Manager and President of the Industrial Division of Nanjing High Speed & Accurate Gear Group CO., Ltd., along with representatives from the industrial chain partners, attended the event to witness this milestone. The occasion marks a significant breakthrough in China's field of precision rolling equipment for super large ring components.
A Defining Moment for the Manufacturing Industry
The NHJ-ZJ series ring rolling machine’s main reducer, developed amid the drive for localization, has achieved significant breakthroughs in technological innovation by leveraging NGC’s low-speed, heavy-duty industrial gearbox technology system. NGC’s gears incorporate composite profile modification technology and efficiency enhancement technology. The housing has undergone stiffness analysis and utilizes topological optimization technology, as well as system modal analysis, providing systematic theoretical support for the product's development. The product features low operating vibration, minimal system temperature rise, high load-carrying capacity, high transmission efficiency, and high reliability, providing stable and reliable power transmission support for the production of ring forgings.
Forging the Future with Unwavering Strength
At the ceremony, Mr. Ding expressed his gratitude to Iraeta Energy Equipment Co., Ltd. (hereinafter referred to as “Iraeta Energy Equipment”), General Technology Tianjin Tianduan Press Co., Ltd. (hereinafter referred to as “Tianduan Press”), Jinan Volsz Numerically Controlled Machinery Co., Ltd. (hereinafter referred to as “Jinan Volsz Numerically Controlled Machinery”) and other companies for their steadfast support over the years in technological collaboration, scenario validation, and the shared prosperity of the industrial chain. He emphasized that every leap forward for NGC is inseparable from the concerted efforts of upstream and downstream partners within the industrial chain. The launch of the 22-meter super large ring rolling machine main gearbox that was launched this time is a significant milestone in NGC's over 50 years of dedication to the industrial transmission field, highlighting the R&D capabilities of domestic high-end equipment.
General Manager Niu Yubing of the Transmission Division at Iraeta Energy Equipment, Deputy General Manager Zhang Jingbo of Tianduan Press, and General Manager Zhao Qiang of Jinan Volsz Numerically Controlled Machinery all emphasized in their speeches that the outcomes of this cooperation serve as a model of collaborative innovation in the equipment manufacturing industry. All parties are committed to further enhancing cooperation in the fields of gear transmission and heavy equipment manufacturing, working together to develop more globally competitive "heavyweights."
At the ceremony venue, with the completion of the ribbon-cutting ceremony, the main gearbox for 22-meter ring rolling machines was officially delivered, marking a new stage in the development of China's ultra-large ring component machining technology.
