Roller Pinion And Rack
Cycloid Rack
Cycloid motion refers to the trajectory traced by a fixed point on the circumference of a circle as it rolls along a straight line (or another circle). The resulting curve is called a cycloid. RAS REDUCER integrates proprietary patented designs with in-house manufacturing capabilities to produce cycloid roller rack assemblies featuring high precision, high strength, high durability, high speed, low dust, low backlash, low noise, and low vibration. These assemblies meet the stringent standards required in the semiconductor, automation, and cleanroom industries.
Key Advantages of Roller Pinion & Rack：
• High Precision: Patented design eliminates backlash, combined with dedicated grinding machines to improve positioning accuracy and repeatability.
• High Strength: Preload design enhances stability during engagement, ensuring low wear and high accuracy. Additional processing can further increase overall strength.
• High Load Capacity: Larger equivalent module provides higher structural strength than involute gears of the same size, improving overall load capacity.
• High Durability: High overall rigidity allows the system to withstand heavy loads.
• Low Friction: Internal rollers rotate freely, effectively reducing friction in transmission.
• High Speed: Proprietary design ensures smoother, quieter engagement compared to conventional involute racks, enabling long-distance, high-speed, and stable motion.
• Low Dust: Patented design eliminates backlash while reducing wear, achieving virtually dust-free operation.
• Low Backlash: Preload adjustment preserves the necessary fine clearance, preventing gear jamming and ensuring stable rolling transmission.
• Low Noise and Low Vibration: Smooth engagement reduces impact and noise. High transmission capacity minimizes vibrations at the end of the transmission mechanism, ensuring stable operation.
Applications of Roller Pinion & Rack：
• Robotic Joint Modules – Glass & Wafer Transfer: Smooth lifting, low backlash, stabilizes the end of the fork, shortens calibration and setup time, improves efficiency, and reduces risk of breakage.
• Industrial Automation Equipment: High-precision positioning and high-speed transmission improve automation efficiency.
• Semiconductor Manufacturing Equipment: Zero backlash and repeatable high precision allow accurate transfer of delicate components to designated positions.
• Machine Tools: Suitable for high-precision transmission applications such as gantry milling machines and laser cutters.
• Medical Equipment: High precision, low dust, and low noise ensure accurate positioning, reduce environmental contamination, and provide a quiet working environment for medical staff.
• Cleanrooms: Designed to meet high-speed transmission requirements without continuous lubrication or consumables. Full-roller engagement ensures wear-free, dust-free operation, reducing contamination.
Reminder of Roller Pinion & Rack：
The patented racks designed by RAS REDUCER feature a unique structure and are not compatible with rollers from other manufacturers. To ensure optimal performance and safety, please order and install the complete set (rack and rollers) together. RAS REDUCER is not responsible for any issues resulting from the use of non-RAS REDUCER products.
