Adjustable Stroke Cycloidal Gearbox (Variable Amplitude)
Adjustable Stroke Cycloidal Gearbox (Variable Amplitude)
When a fixed gear ratio isn’t enough—and your application demands the ability to dynamically tune output stroke, adapt to shifting torque profiles, or minimize vibration on the fly—the Artix Motion Variable Eccentricity Cycloidal Reducer (CVA Series) is the ultimate engineering solution.
By allowing precise adjustment of the input shaft's eccentricity offset, this breakthrough reducer transitions from a rigid, high-torque speed reducer to an adjustable stroke mechanism. Built on our core cycloidal platform, it delivers this cutting-edge adaptability alongside the legendary shock-load resistance and zero-backlash precision of standard cycloidal drives.
We offer fully tailored housing diameters, custom eccentric offsets, specialized hollow bore dimensions for internal cable routing, custom output shafts, and motor-matching input adapters designed exactly to meet your unique drive architecture.
Primary Areas of Use
- The CVS Series is purpose-built for advanced mechanical systems requiring variable-amplitude inputs or smart kinetic adaptation:
- Precision Indexing & Variable Pressing: Adjusts mid-cycle to change pressing forces or stroke limits in high-speed manufacturing cells.
- Advanced Robotics & Kinematic Joint Testing: Simulates variable resistance and alters motion profiles dynamically for advanced robotic links or industrial testing rigs.
- Vibratory Feeder & Sorting Automation: Fine-tunes mechanical vibration amplitudes on the fly to match varying material densities and flow rates perfectly.
- Heavy Machinery Adaptations: High-torque steering, cam modulation, and adaptive wheel or conveyor drives operating under unpredictable load conditions.
