Transmission gear is one of the core components of the transmission, responsible for transferring the power generated by the engine, and adjust the output torque and speed as needed. Here are some key points for transmission gears:

1. Definition:

Transmission gear is a group of gears inside the transmission box, which transmits power by engaging, and realizes transmission and shift functions through different combinations of gears.

2. Function:

Speed change: By changing the combination of gears, the gearbox can change the speed of the output shaft, so as to achieve a change in speed.

Shift: When the vehicle is driving, the transmission gear can be automatically or manually switched to the appropriate gear ratio according to the speed and load to keep the engine in an efficient working range.

3. Type:

Spur gear: simple structure, high transmission efficiency, but large noise and vibration.

Helical gear: Compared with straight gear, helical gear transmission is more stable and less noisy, but the manufacturing complexity is higher.

Helical gear: has better transmission performance and less noise, but is more difficult to manufacture.

4. Design:

Gear should be designed with strength, wear resistance and precision in mind. Gear material is usually alloy steel, and through heat treatment to improve its hardness and wear resistance.

The precision of the gear is crucial to the performance of the gearbox, so it is necessary to strictly control the machining precision of the gear during the manufacturing process.

5. Gear ratio:

The ratio of gears in the gearbox determines the variation in engine output torque and speed. Different gear ratios are suitable for different driving conditions.

6. Maintenance and replacement:

Transmission gears may be worn or damaged after long-term use, so regular maintenance and replacement are required to ensure the normal operation of the gearbox.

The design and manufacture of transmission gears is essential to ensure that vehicles run smoothly and efficiently, and as a result, research and innovation in this area continues.
