1. Input Shaft Rotation
The input shaft connects directly to the motor, rotating an eccentric bearing
This eccentric motion initiates the cycloidal reduction process
Provides the foundation for high torque transmission
2. Cycloidal Disc Movement
Eccentric bearing causes oscillation of hardened cycloidal discs
Discs feature precision-engineered tooth profiles
Meshes with stationary pins in the housing for smooth power transfer
3. Power Output Generation
Disc oscillation creates planetary rotation movement
Rotation transfers to output shaft via high-strength rollers
Tooth differential enables high reduction ratios (up to 1:119)
Delivers low-speed, high-torque output with minimal backlash (±1 arcmin)
