⚙️ Why Hardened Gears for Robot Fingers?
In humanoid robotic hands, gears operate under high frequency, micro-load cycling. Standard gears often fail due to wear and deformation. Hardened gears significantly improve:
- Wear resistance under continuous operation
- Dimensional stability in precision assemblies
- Long service life under micro torque transmission
Compared with non-hardened gears, hardened gears ensure stable backlash and consistent performance over millions of cycles.
