The production of gearbox gears is a complex and precise process, which mainly includes the following stages:

1. Design and planning: Based on product requirements and specifications, design the size, number of teeth, module, and tooth groove shape of the gear.

2. Material preparation: Select suitable metal materials, such as steel or alloys, and perform heating treatment to improve hardness and strength.

3. Gear manufacturing: Gear manufacturing mainly consists of two steps: cutting and grinding. During the cutting process, it is necessary to ensure the accuracy of the geometric shape, tooth width, and tooth groove of the gear. Grinding is used to improve the surface quality and accuracy of gears.

4. Heat treatment: Adjust the hardness and strength of the gear through steps such as heating, quenching, and tempering.

5. Surface treatment and coating: increase the wear resistance and service life of gears.

6. Quality testing: Testing various parameters such as gear size, hardness, tooth profile, and surface quality.

7. Assembly and Debugging: Install the manufactured gears into the gearbox and conduct debugging and testing.

8. Inspection and packaging: Complete the final inspection of the gears and carry out appropriate packaging and labeling.
