In recent years, with the development of technology and the upgrading of the industry, the demand for gears has increased, and the quality and precision requirements for gears have become higher and higher. As the core and key components of the transmission system, gears not only transmit power and energy, but also reflect the level of industrial development of a country. In recent years, my country's industrial technology level has developed by leaps and bounds, but there is still a certain gap between the performance of gear products and foreign countries, such as short service life, poor load-bearing capacity and unstable quality.
