Gear & Pinion Induction Hardening Services in Punjab
Explore gear and pinion hardening processes that enhance wear resistance for automotive and farm machinery parts.
Gears and pinions are the backbone of motion and power transmission systems — from tractors and industrial machinery to automobiles and heavy equipment. They operate under extreme loads, high torque, and constant friction, making them prone to surface wear, pitting, and fatigue failure if not properly hardened.
Understanding Gear Induction Hardening
Induction hardening is a localized heat treatment process that strengthens the surface of metal components using electromagnetic induction. In gear induction hardening, only the gear teeth or specific contact zones are heated and quenched — ensuring that the core remains tough and ductile while the surface achieves high hardness (up to 60 HRC).
Pinion Hardening Process Explained
Pinions, typically smaller gears that engage larger gears, experience high rotational stress and load concentration. For these components, the pinion hardening process is optimized for fine tooth geometry, controlled case depth, and minimal distortion.
Materials Used in Gear & Pinion Hardening
| Material Grade | Common Use | Achievable Hardness (HRC) |
|---|---|---|
| EN8 (C40) | Light-duty gears | 50–54 |
| EN19 (4140) | Transmission shafts & pinions | 52–58 |
| EN24 (4340) | Heavy-duty automotive gears | 55–60 |
| 20MnCr5 | Case hardening steel for precision gears | 58–62 |
| 16MnCr5 | Pinions & sprockets | 58–60 |
Benefits of Gear Induction Hardening
| Benefit | Description |
|---|---|
| Enhanced Surface Hardness | Increases gear tooth resistance against wear and fatigue. |
| Improved Load Bearing Capacity | Hardened surfaces sustain heavy torque without deformation. |
| Longer Service Life | Reduces maintenance frequency and downtime. |
| Localized Hardening | Only functional areas are hardened, maintaining the core’s ductility. |
| Excellent Repeatability | PLC-controlled process ensures consistency for mass production. |
