With the continuous progress of science and technology and the popularization of the concept of Industry 4.0, the modern machinery manufacturing industry is undergoing unprecedented changes. Especially in the pursuit of precision, high efficiency and light weight, transmission gear technology and aerospace manufacturing have become the key areas of industry development. This paper will discuss how they play an important role in the machinery manufacturing industry and analyze their mutual influence.

1. Development and importance of transmission gear technology.

As one of the most basic and important components of mechanical equipment, the performance of transmission gear directly affects the running efficiency and stability of the whole system. In recent years, with the progress of material science and the innovation of design methods, such as using high-strength alloy steel or composite materials to manufacture gears and using finite element analysis to optimize the design, transmission gears not only achieve higher bearing capacity and longer service life, but also develop towards miniaturization and lightweight.

2. The influence of special requirements in aerospace field on transmission system.

The aerospace industry has very strict requirements for parts and components, which need to ensure absolute safety and reliability and excellent working performance. This urges the transmission system in this field to have the characteristics of high precision, high temperature resistance and corrosion resistance. For example, the gear components used in rocket engines or aircraft engines should not only be able to withstand high-pressure and high-speed operating conditions in extreme environments, but also ensure long-term trouble-free operation. Therefore, the new materials and technologies developed for these specific requirements provide new ideas and development space for the design of transmission gears.

3. The interaction between them promotes and develops.

On the one hand, the progress of transmission gear technology has promoted the level of aerospace manufacturing. The application of new materials reduces the weight and improves the efficiency; Advanced machining technology ensures the consistency of gear size and surface quality, thus meeting the harsh standards of aircraft for power transmission devices. On the other hand, in order to adapt to the challenges in the aerospace field, it also promotes related basic research and technological innovation, such as predicting the behavior of gears under different working conditions through computer simulation, and then guiding the development and improvement of actual products.

In a word, transmission gear and aerospace manufacturing are complementary. The former provides strong support for the foundation, and the latter in turn promotes the in-depth exploration and improvement of the former. future, under the background that new materials and new processes are constantly emerging, the combination of the two will be closer and lead the machinery manufacturing industry to a higher level.
