In the field of mechanical engineering, transmission system is one of the key components to realize power transmission and speed conversion, and gear, as the core component of transmission system, plays a vital role. This paper will discuss the design, manufacture and marking technology of transmission gears, aiming at providing reference for engineers and technicians in related fields.

Gear design principle

The design of gears needs to consider a variety of factors, including but not limited to working environment, load conditions, speed requirements and so on. According to different uses, gears can be divided into straight cylindrical gears, helical cylindrical gears, bevel gears and other types. Each type of gear has its own specific application scenarios, for example, spur gear is suitable for low-speed and light-load working environment; The helical cylindrical gear, on the other hand, performs better under high-speed and heavy-load conditions because it can run smoothly.

manufacturing process

With the development of science and technology, the manufacturing technology of modern gears has become very mature. Common manufacturing methods include cutting (such as gear hobbing and gear shaping), powder metallurgy forming, cold and hot forging forming and so on. Among them, cutting is the most traditional and widely used method, which accurately cuts the blank by special machine tools to form the required gear profile. In recent years, with the development of 3D printing technology, it is gradually possible to produce gears with complex shapes or small batch customization by using additive manufacturing.

Marking technique

In order to facilitate identification and management, gears are usually marked. These marks not only help to track the production batch and model information of products, but also can be used to guide the installation and use. Traditional marking methods mainly include laser marking and chemical etching. Laser marking is widely used for its high efficiency, high definition and permanence. For some gears with special materials or surface treatment, chemical etching can ensure that the marking will not affect the performance of the gears.

In a word, the manufacturing of transmission gears and their marks is a technical activity involving multidisciplinary knowledge. From design to finished product, every link is crucial. In the future, with the continuous emergence of new materials and new technologies, the design and manufacture of gears will be more accurate and efficient, and meet more diverse needs. For practitioners, it is very necessary to keep learning new technologies and mastering industry trends, which can not only improve individual competitiveness, but also promote the progress and development of the whole industry.
