(Reposted from BIT News Network) On July 26, the "2015 National Gear Technology Symposium," hosted by Beijing University of Technology and the Beijing Engineering Research Center for Precision Measurement, Control Technologies, and Instrumentation, was held at BIT. This year's conference theme was "Gear Technology under China Manufacturing 2025." Experts attending the event exchanged ideas and discussed topics including the current state of the gear industry, gear-related issues under the "13th Five-Year Plan" and the National Key Foundation Project, precision transmission technologies tailored for robots and CNC machine tools, lightweighting techniques for gearboxes, advanced testing methods for gears and gearboxes, as well as the latest developments in gear standards and China's gear metrology transfer system.
Nie Zuoren, Vice President of Beijing University of Technology, Wang Changming, Executive Vice President and Secretary-General of the China General Machinery Parts Industry Association, Feng Guang, Chairman of the Gear Branch, and other leaders attended the opening ceremony of the conference. More than 140 experts and scholars from companies, universities, and research institutes in the gear industry participated in the meeting.
At the opening ceremony, Vice President Nie Zuoren delivered a welcoming speech on behalf of the university and briefly introduced Beijing University of Technology’s history and ongoing development. Vice President Nie emphasized that mechanical engineering is one of Beijing Tech’s most traditional disciplines, while also highlighting the university’s distinct strengths in interdisciplinary fields. He expressed his hope that the conference would serve as a valuable opportunity for experts and scholars to strengthen their connections and collaboration with Beijing University of Technology.
Chairman Feng Guang analyzed the current situation facing the gear industry as China’s economy enters a new normal. He emphasized that achieving industrial development and upgrading hinges on relying on "management innovation" and "technological innovation"—these "two wheels," with technological innovation taking center stage. Chairman Feng discussed the development direction of the gear industry during the 13th Five-Year Plan period, focusing particularly on cutting-edge technologies and advanced manufacturing processes. Vice Chairman Wang Changming summarized the industry's current challenges, highlighting the need for the association to leverage its role in coordinating the sector, especially as it targets strategic emerging industries such as robotics. Meanwhile, Honorary Chairman Wang Shengtang pointed out that the gear industry must align itself with the national initiatives outlined in "Made in China 2025" and the integration of IT with industrialization, while placing particular emphasis on advancing four key areas: market dynamics, business models, manufacturing technologies, and software platforms—and notably, "cloud computing." Secretary-General Wang Changlu from the Gear Branch then provided an insightful interpretation of China’s "13th Five-Year Plan" Development Outline for the gear industry. In addition, Vice Secretary-General Shi Zhaoyao, who is also a professor at Beijing University of Technology, delivered a detailed presentation on the theory of overall gear errors. He noted that "overall gear error" technology—a pioneering innovation developed in China and successfully exported to Germany as a high-tech solution in the 1990s—has unfortunately seen little progress over the past two decades. Professor Shi delved into the underlying reasons for this stagnation and shared his team’s ongoing research efforts, covering topics such as the theory of overall gear pair errors, generalized gear error theory, and the development of rapid gear-testing instruments. Finally, Professor Shi highlighted the ongoing work being undertaken by his team to standardize terminology and definitions within the machinery industry, encouraging industry professionals to actively participate in this critical initiative.
This seminar featured 8 invited keynote speeches and 13 academic presentations. Experts including Pei Zhiming from Getrag (Jiangxi) Transmission Systems Co., Ltd., Chen Demu, Chairman of Jiepai Holding Group Co., Ltd., Hua Lin, Dean of the School of Automotive Engineering at Wuhan University of Technology, Researcher Xue Zi from the Length Metrology Division of the National Institute of Metrology, China, Jin Guozhong from Nanjing South Railway Rolling Stock Equipment Research Institute Co., Ltd., Professor Wang Tie from the Gear Research Institute at Taiyuan University of Technology, Professor Wang Yanzhong from Beijing University of Aeronautics and Astronautics, and Professor Han Jiang from Hefei University of Technology—along with 7 other distinguished speakers—shared the latest insights and research findings in the gear industry, covering areas such as enterprise management, gear manufacturing, testing, lubrication, and metrology. Additionally, 13 experts—including Zhang Jing from Zhejiang Shuanghuan Transmission Machinery Co., Ltd., Professor Li Haitao from China Agricultural University, and Dr. Zhu Libin from the State Key Laboratory of Mechanical Transmission at Chongqing University—engaged in discussions on pressing issues in China's robotics reducer development, as well as topics like face-gear hobbing, efficient and clean gear machining processes, precision forging of gears, low-noise design and manufacturing of gear drives, and gear meshing theory under CNC manufacturing technologies.
This national gear technology symposium successfully built a bridge for communication, enabling scholars to align their research achievements in gear theory with the technical needs of industry. At the same time, it helped young scholars gain a clearer understanding of the industry’s current state and emerging trends, reinforcing their confidence in pursuing a career focused on fundamental gear research.
