As one of the key parts of the automobile, the performance and characteristics of the automobile gear play an important role in the automobile industry. Here are a few key points about car gears:
1. Functions and effects:
Automotive gears are mainly used to transmit the power of the engine, and realize the movement of the vehicle through transmission, steering and other mechanisms.
2. Type:
According to different applications and needs, automotive gears can be divided into straight gear, helical gear, bevel gear, planetary gear and so on.
3. Machining accuracy:
Gear machining accuracy is the key index to measure its quality, which directly affects the transmission performance and service life of gear.
4. Materials:
Automotive gears are usually made of high-performance alloy steel or special steels, such as 20CrMnTi, to ensure their requirements in terms of high strength and wear resistance.
5. Main features:
Transmission efficiency: The transmission efficiency of the gear is higher, up to more than 90%.
Durability: The gear can maintain good wear resistance and fatigue resistance under high temperature, high pressure and high load conditions.
Compact structure: The gear mechanism is usually compact in structure and takes up little space.
6. Advantages:
Simple structure, compact, easy to maintain and replace.
High transmission precision, smooth operation, low noise.
Can adapt to high speed and heavy load working environment.
7. Disadvantages:
The reverse efficiency is high, and it is easy to produce recoil phenomenon, which has an impact on the operator's stability.
The processing cost is relatively high, especially in the requirements of high precision and high wear resistance.
8. Development trend:
With the popularity of new energy vehicles, the precision requirements of automotive gears are getting higher and higher.
The innovation and development of gear manufacturing technology, such as wedge rolling technology and isothermal normalizing process, constantly promote the improvement of gear performance.
9. Market demand:
With the rapid development of the global automobile industry, the demand for automotive gear market continues to grow, and higher requirements are put forward for the technical level and product quality of gear manufacturers.
