The mechanically enclosed ultra-high-speed test bench developed by China Pingyao Reducer was successfully debugged

Recently, the "ultra-high-speed mechanical power closed test bench" carefully developed by Shanxi Pingyao Reducer Co., Ltd. (referred to as "Pingyao Reducer") has been successfully debugged. Its gear linear speed peak reaches 162m/s and the speed is as high as 50,000 revolutions per minute.

With the vigorous development of my country's new energy vehicle industry and the independent rise of aerospace technology, the speed of internal gears in new energy vehicles and aero engines has been rising day by day, and has exceeded tens of thousands or even hundreds of thousands of revolutions under some working conditions. Therefore, the research on fatigue life, dynamic characteristics and lubrication characteristics of high-speed gears has become a top priority. However, domestic testing equipment is still mostly dependent on imports. In view of this, Pingyao Reducer and the Gear Research Institute of the top domestic university have jointly promoted the research and development and trial production of this project.

After the successful implementation and operation of the "ultra-high-speed mechanical power closed test bench", it can provide strong support for the fatigue life test and dynamic characteristics research of high-speed gears, and accelerate the progress of fatigue life characteristics research of conventional gears. At the same time, the test bench can also seamlessly connect with the company's core patented technology "mechanical loader" to achieve stepless and dynamic load adjustment during the test process, further improving the accuracy and flexibility of the test.

The successful development of the "ultra-high-speed mechanical power closed test bench" is not only a major technological breakthrough, but also a brilliant spark of teamwork and wisdom. Here, we express our deepest gratitude to the decision-making level with Chairman Liang Xinwen as the core, thanking them for their firm support and strategic guidance; we pay high tribute to the technical team led by Wu Dongdong, whose hard work day and night has solved the technical problems; the careful deployment of Minister Yan Wanjian and the close cooperation of Director Lei Weimin, like the wings of the project, ensure the stability and efficiency of the research and development process; the timely support of the leaders of the design and power department and Master Zhang Zhiyong has added indispensable strength to the project; the hard work of workshop masters such as Liu Jianan, Li Sansheng, Liang Sheng, Qin Yongzhi, and Ren Wentao is a key link in transforming design concepts into real results.

This success is not only an affirmation of Pingyao Reducer's past efforts, but also an encouragement and enlightenment for the future exploration. It has accumulated valuable experience for Pingyao Reducer, enhanced the team's self-confidence, and pointed out the direction for Pingyao Reducer to move forward. Looking into the future, Pingyao Reducer will take this opportunity to continue to deepen research and strive to reach the peak of science and technology.
