Transmission gear, as a part of the precision mechanism inside the automobile gearbox, is the key to achieve power transmission and speed regulation. Through precise meshing and separation, they enable the vehicle to obtain appropriate power output under different working conditions.

The following ATV gear, gear customization and Zhejiang auto gear manufacturers are talking about the key points of transmission gear design.

1. Material selection: transmission gear needs to withstand high load and high-speed rotation, so the material must have high strength, good wear resistance and fatigue resistance. Commonly used materials are alloy steel, carburized steel and so on.

2. Precise machining: The precision of the transmission gear is extremely high, and high-precision equipment such as CNC gear grinding machine should be used in the machining process to ensure that the gear tooth shape, tooth pitch and other parameters meet the design requirements.

3. Surface treatment: In order to improve the service life and corrosion resistance of the gear, surface hardening, galvanized and other treatments are usually carried out.

4. Tooth shape design: According to different application requirements and transmission characteristics, the tooth shape design of transmission gear has straight teeth, helical teeth, miter teeth, etc. Each tooth shape has its specific advantages and disadvantages.
