MOTION CONTROL AT THE SPEED OF TECHNOLOGY™

Cycloidal Speed Reducers
Cycloidal (planocentric) Gearboxes employ eccentric motion to achieve speed reduction. It uses non-circular or eccentric motion to convert input rotation into a wobbly cycloidal motion. This motion is then converted back into a circular output rotation. During this process, speed reduction occurs.
Unlike strain wave gearing which employs a flexible cylinder that doesn’t move in its entirety but stretches to mesh with the internal circular spline gear to achieve a type of cycloidal motion, the cycloidal (planocentric) drives will actually move the entire internal gear in an eccentric motion.
GAM RoboCycloidal Gearboxes:
The RoboCycloidal series from GAM delivers high-precision, zero-backlash performance for robotic and automation applications that demand high torque and durability.
Built around a true cycloidal mechanism, these gearboxes minimize wear, absorb shock loads, and maintain repeatability over long duty cycles.
Each unit integrates a cycloidal reducer with a servo motor adapter, offering a compact, high-torque gearbox solution for use in robotic joints, rotary positioners, and indexing systems.
Key Features:
- True cycloidal drive mechanism (not cam-based)
- Near-zero backlash for precision positioning
- Integrated servo motor adapter with universal compatibility
- Solid shaft and hollow bore output options
- Handles shock loads up to 500% of rated torque
- Consistent performance in high-duty-cycle environments
