Metal gear processing technology (for reference)

Metal gear processing technologyThe relevant instructions are as follows, for reference and understanding, if you are unclear or related requirements, you can consult EP free of charge.

Metal gear processing technology:

1. Casting billet

At present, hot die forging is still a widely used blank forging process for automotive gear parts.In recent years, cross wedge rolling technology has been widely promoted in shaft machining.

2. Normalizing

Can get suitable for follow-upgearThe hardness of the cutting process and the preparation of the structure for the ultimate heat treatment effectively reduce the heat treatment deformation.

Practice has proved that the use of isothermal normalizing has effectively changed the general normalizing disadvantages, and the gear quality is stable and reliable.

3. Turning

All gears are processed by CNC machine tools, using mechanical clamping without heavy grinding of turning tools, so that the aperture, end surface and outer diameter processing can be completed simultaneously in one clamping, which not only ensures the verticality requirements of the vertical plane of the inner hole and the end surface, It also ensures that the size of the mass production of tooth blanks is small.

4. Rolling and shaping

Gear hobbing machines and gear shaping machines are used for processing gears.

5. Shaving teeth

Radial gear shaving technology is widely used in large quantities because of its high efficiency, easy realization of the modification requirements of the design tooth profile and tooth direction, etc.Car gearin production.

6. Heat treatment

For products that no longer undergo gear grinding after heating, stable and reliable heat treatment equipment is essential.

7. Grinding

Mainly the heat-treated gear inner diameter, end face, shaft outer diameter and other parts are finished to improve dimensional accuracy and reduce form and position tolerances.

8. Trimming

Detect and clean the teeth with bumps and burrs to eliminate the abnormal noise caused by them after assembly.It is completed by listening to the sound of a single pair of meshing or observing the meshing deviation on a comprehensive inspection instrument.

The above description of metal gear processing technology includes but is not limited to, welcome to add if there are any deficiencies.
