Working Principle
Input Rotation: Motor or drive system provides rotational power to the reducer’s input shaft.
Gear Reduction: An internal planetary or helical gear train reduces speed by the gear ratio (e.g., 3:1, 10:1, 100:1).
Torque Multiplication: As speed decreases, torque increases proportionally at the output shaft.
High Precision Motion Output: The precision-ground gears and low-backlash design ensure exact positioning and smooth motion.
Key Features
High Precision: Backlash as low as ≤1 arc-min for servo-grade models.
High Efficiency: Transmission efficiency up to 97–99%.
High Torque Density: Compact size with powerful output torque.
Smooth and Quiet Operation: Helical gear designs reduce vibration and noise.
Durable Construction: Alloy steel gears and hardened housings ensure long service life.
Mounting Versatility: Compatible with servo, stepper, and AC motors.
