Gear machining process

XNUMX. High-precision gear machining process:

1. Rough forging

2. Normalizing

3. The shape of the rough turning, leaving a machining allowance of 2mm for each part; outer circle and end face

4. For each part of the fine turning, the inner hole is to φ84.8H7, the total length is 0.2mm outside the machining allowance, and the rest is up to the size;

5. Gear hobbing (the tooth thickness leaves a grinding allowance of 0.25~0.35m); inner hole and end face A

6. Chamfering; inner hole and end face A

7. Fitter deburring

8. Heat treatment: tooth C52

9. Key slot; inner hole (for alignment) and end face A

10. Large end face A by grinding; inner hole

11. Surface grinding plane B, total length to size; end face A

12. Grind the inner hole from 85H6 to size; inner hole and end face A (for alignment)

13. Grinding teeth; inner hole and end face A

14. Final inspection.

XNUMX. General gear machining process:

1. Forging

2. Normalizing

3. Each part of the rough turning has a margin of 1.5mm; outer circle and end face; turret lathe

4. For each part of the fine car, the plug gauge line from the inside to the taper hole is exposed 6~8m, and the rest meets the drawing requirements; outer circle, inner hole, end face; C616

5. Gear hobbing; inner hole, end face B; Y38

6. Chamfering; inner hole, end face B; chamfering machine

7. The key slot meets the drawing requirements; outer circle, end face B; slotting machine

8. Deburring

9. Shaving teeth; inner hole, end face B; Y5714

10. Heat treatment: tooth C54

11. Grind the inner cone hole until the small end of the plug gauge is flat; outer circle, end face B; M220

12. The honing tooth meets the drawing requirements; inner hole, end face B; Y5714

13. Final inspection.
