A planetary reducer is a precision mechanical device that uses the principle of planetary gear transmission to achieve speed reduction and torque increase. Its core structure includes a sun gear, multiple planet gears, an internal ring gear, and a planet carrier. Through multi-stage planetary gear meshing, it efficiently converts the high-speed rotation of the motor into low-speed, high-torque output. The housing is made of high-strength aluminum alloy or cast steel, featuring a compact structure, high transmission efficiency (>97%), and minimal backlash (≤3 arc minutes). It significantly enhances the transmission accuracy and load capacity of equipment and is widely used in high-precision, high-torque transmission scenarios.
Product Applications
1. Industrial Robots: Joint drives (such as SCARA robots, six-axis robotic arms) to achieve precise motion control.
2. Precision Machine Tools: CNC machine tool feed systems, milling machine spindle drives to ensure machining accuracy (≤0.01mm).
3. Semiconductor Equipment: Wafer transfer robotic arms, lithography machine alignment systems to meet sub-micron positioning requirements.
4. Aerospace: Satellite antenna adjustment mechanisms, drone landing gear drives to adapt to harsh working conditions.
5. New Energy Industry: Photovoltaic module production equipment, lithium battery winding machines to improve production efficiency and stability.
6. Logistics Automation: Intelligent warehouse AGV drive wheels, high-speed sorting lines to achieve smooth heavy-load transportation.
Product Features
1. High Load Capacity: Uses high-strength alloy steel gears (20CrMnTi) with carburizing and quenching treatment (HRC58-62), maximum output torque up to 20,000Nm, suitable for ultra-heavy load equipment.
2. Efficient and Precise Transmission: Planetary gears with equal load distribution, transmission efficiency >97%, energy saving of 10%~15%; backlash ≤3 arc minutes, positioning accuracy improved by 30%.
3. Compact Structure: Volume reduced by 30% compared to traditional reducers, power density increased by 40%, saving installation space.
4. Low Noise Operation: Gears precision ground (ISO 6 grade accuracy), noise below 65dB(A), vibration intensity ≤1.8mm/s (ISO 10816 standard).
5. Maintenance-Free Design: NSK/SKF bearings with lifetime lubricating grease, maintenance cycle ≥5 years, reducing downtime risk.
6. High Adaptability: Supports custom gear ratios (i=3~1000), hollow shaft structure, adaptable to explosion-proof/corrosion-resistant environments.
Product Functions
1. Torque Amplification: Amplifies motor torque by 5 to 100 times to meet low-speed, high-load working conditions.
2. Precise Speed Control: Through custom gear ratios (i=3~1000), achieves precise output speed adjustment from 0.1 to 1000 r/min.
3. Direction Change: Supports 90° direction change (orthogonal output) or coaxial output, flexibly adapting to equipment layout.
4. Overload Protection: Built-in torque limiter (such as the coupling shown in the picture), instantaneous overload protection capacity up to 180%.
5. Vibration and Noise Reduction: Flexible planet carrier design plus housing vibration damping pads effectively suppress resonance (vibration reduced by 40%).
