Hollow output shaft design facilitates cable and piping routing, with factory-installed flange seals and pre-filled RV lubricant

● Two-stage reduction system:

Primary stage: Involute planetary gear transmission for initial speed reduction

Secondary stage: Cycloid pinwheel transmission for further speed reduction and torque stabilization

● Rigid impact-resistant structure:
a. Rigid disc support at output ensures even load distribution and minimizes deformation
b. Multi-crank shaft design with high-precision bearings effectively disperses stress impacts

● Compact enclosed layout:
Transmission mechanism integrated within planetary carrier support bearings significantly reduces axial dimensions

Advantages

● High load capacity and precision:
a. Torque range: 50-7000 N·m, suitable for heavy-duty robotic arms (welding, material handling, etc.)
b. Stable backlash precision (<1 arcmin) with minimal repeat positioning error

● Extended service life and reliability:
a. Multi-tooth meshing (≥30 teeth) ensures even wear distribution (service life: 6,000-10,000 hours)
b. Superior fatigue resistance compared to harmonic drives, ideal for 24/7 continuous operation

● High-efficiency transmission adaptability:
a. Transmission efficiency: 85%-95% with minimal energy loss
b. Wide reduction ratio range (31-203), adjustable through planetary gear tooth configuration

● Outstanding dynamic performance:
a. Low-vibration design ensures smooth robotic arm operation without end-effector jitter
b. Rapid acceleration response enables high-speed trajectory tracking
