DIN6 Robot Finger Gear Shaft | M0.5 Hardened Micro Gear for Humanoid Hands

Custom DIN6 robot finger gear shaft with M0.5, 18 teeth, nitrided surface hardness HV750–920 and aerospace-grade manufacturing control for humanoid robot hand actuators.

Product Overview

This DIN6 Robot Finger Gear Shaft is designed for compact humanoid robot hand mechanisms where small size, stable torque transfer and long-cycle reliability are critical. In dexterous robot hands, gears are exposed to repeated gripping, direction changes and side-load conditions. Ordinary micro gears may suffer from tooth wear, backlash growth or fatigue failure.

This gear shaft is manufactured based on a precision drawing with M0.5 module, 18 teeth, 20° pressure angle and 6-h accuracy grade according to GB2363-90. The nitrided tooth surface improves wear resistance, while the tempered core supports dimensional stability and fatigue strength.

FAQ

Q1: Why is DIN6 accuracy important for robot finger gears?
DIN6 accuracy helps improve tooth meshing consistency, reduce motion fluctuation and support more repeatable finger movement.

Q2: Is this gear suitable for high-cycle robot hand operation?
Yes. The nitrided surface and tempered core are suitable for applications requiring repeated motion and improved wear resistance.

Q3: Can this gear shaft reduce backlash?
Gear accuracy, tooth consistency and mating gear design can help control backlash. Final backlash depends on the complete actuator assembly.

Q4: Can you manufacture this gear based on customer drawings?
Yes. MH supports custom micro gear manufacturing based on 2D drawings, 3D models or samples.

Q5: What information is needed for quotation?
Please provide drawing, material, heat treatment requirement, DIN grade, quantity, mating gear data and application background.
