In May 2023, I went to the guest factory in St. Petersburg to visit the production workshop and complete equipment. After receiving the information, I conducted a 3-hour transmission technology exchange, which covered from the design of the transmission, to precision manufacturing, to efficient application and careful attention. A comprehensive discussion of maintenance. In this process, we are committed to unlocking the infinite potential of gearbox technology, improving the performance of mechanical equipment, achieving efficient use of energy, and promoting innovation and development of the entire industry. In this technical exchange, we will delve into the art of gearbox design, including its unique structure, precise transmission ratio calculations, clever design of gears and bearings, and meticulous planning of the lubrication system. Together, these design elements form the backbone of the transmission and determine its performance and durability. Also worthy of attention is the manufacturing aspect of the gearbox. Exquisite craftsmanship and strict quality control methods ensure the precise processing of each gear, the precise assembly of each bearing, and the sturdiness and durability of the box. These details are the charm of gearbox manufacturing technology. In terms of application technology, we will explore the flexible application and optimization strategies of gearboxes in various mechanical equipment. How to accurately match the gearbox according to the characteristics of different mechanical equipment to achieve the best performance and economic benefits will be a topic we discuss together. In addition, gearbox maintenance technology cannot be ignored. We will share our expertise in gearbox maintenance, repair and troubleshooting to ensure that the gearbox is always in optimal condition, extend its service life, and provide long-lasting and stable power support for mechanical equipment. After the technical exchange, we took a group photo in the company conference room and the guests kindly invited us to have lunch at a beautiful seaside restaurant;
