When you need high torque in a small package, cycloid gear reducers deliver what planetary and harmonic drives can’t. These rugged speed reducers use eccentric motion and precision pins to achieve remarkable reduction ratios (up to 300:1) in just two stages—making them ideal for robotics, medical equipment, and heavy-duty automation.
Three standout advantages:
1. Shock Load Tolerance – Handles 500% overloads without damage
2. Zero-Backlash – Critical for repeatable positioning (≤1 arc-min)
3. Compact Design – 30% smaller than equivalent planetary gearboxes
- Robot Joints – Precision movement in collaborative robots
- Medical Imaging – Smooth rotation in CT/MRI gantries
- Packaging Machines – High-cycle reliability under jerky loads
- Wind Turbines – Pitch control systems
An eccentric cam drives a cycloid disc with lobe teeth, which interacts with stationary pin gears. This unique motion:
• Distributes load across multiple contact points (10+ teeth engaged simultaneously)
• Eliminates sliding friction (pure rolling contact)
• Achieves 94%+ efficiency even at high ratios
- Integrated Servo Mounts – Direct coupling to motors
- Hollow Shaft Options – For cable routing
- IoT-Ready Sensors – Vibration/temp monitoring
While initial costs exceed planetary reducers, cycloid drives last 3-5x longer in high-shock applications. Their ability to withstand misalignment and contamination makes them the "tank" of motion control.
