High-torque cycloidal robotic joint actuator with integrated optical encoder
A heavy-duty cycloidal robotic joint actuator built with zero-backlash gearing for high-torque robotic arms.
Standard robotic harmonic drives are fragile under sudden impact loads, while conventional planetary gearboxes suffer from unacceptable mechanical backlash.
AXON / JOINT 01 is an integrated dual-stage cycloidal disc gearbox with 40:1 reduction, distributing shock loads across 60% of the pin contact points simultaneously.
Every chamfer and structural rib is sculpted to minimize rotational inertia while preserving torsional rigidity under 120 N·m peak impact torques.
G2/G3 Curvature
1.5° Minimum
Zero Visual Seam
Modeled with extreme 5-micron precision. Pin spacing, eccentric cam profiles, and crossed-roller bearing raceways are fully parameterized for custom reduction ratios.
A 22mm continuous central hollow bore allows high-voltage motor power and ethernet lines to pass directly through the axis of rotation without cable tangling.
