Example 3: Gears for Servomotors – Helical Gears
Wen-Hsiang machines helical gears for servo gear units to ensure precise, reliable, and efficient servomotors' running. Torque and speed of servomotors are essential for the controlled movements. The quality of gears and motor shafts in the servomotors play an important role in ensuring the smooth and precise control of servomotor torque and speed. Wen-Hsiang's helical gears inspected through a stringent quality control process ensure servo gear units' efficiency and reliability.
| Steps | Measurement items | Dimensions |
| Raw metal inspection | Inspect whether the raw metal matches the description in the material certificate. | |
| Lathing | Dimensional Measurement | Diameter, bearing spacing, depth |
| Milling | Dimensional Measurement | Form and size measurement, compared with scanning and PCD results (pitch diameter, symmetry) |
| Rough hobbing | Gear Test | External tooth profile, lead, pitch, tooth span, tooth profile |
| Heat treatment | Hardness test | Tests for checking material characteristics, hardness, and metallographic examination |
| Grinding (Youdo) | Height measurement, surface roughness, inner diameter, outer diameter | |
| Skiving | Pitch |
