Description

The Flange-Integrated RV Reducer C Series is a precision reduction device specifically designed for mechanical applications. It features a two-stage closed differential gear system consisting of cycloid pinwheels and planetary gears, with a hollow output shaft. The unit comes factory-sealed with flanges and pre-filled with specialized RV lubricating grease, allowing direct installation with servo motors upon unboxing.
In industrial robotics applications:
For robotic arms with end-effector loads ≤20kg, RV reducers are primarily used in base-to-high-load joints (typically Joints 1-4)
For robotic arms with end-effector loads >20kg, all six joints typically employ RV reducers
RV reducers serve as the core transmission component ensuring robotic arm positioning accuracy.


Features
 High load capacity and precision:
a. Torque range: 50-7000 N·m, suitable for heavy-duty robotic arms (welding, material handling, etc.)
b. Stable backlash precision (<1 arcmin) with minimal repeat positioning error


 Extended service life and reliability:
a. Multi-tooth meshing (≥30 teeth) ensures even wear distribution (service life: 6,000-10,000 hours)
b. Superior fatigue resistance compared to harmonic drives, ideal for 24/7 continuous operation


 High-efficiency transmission adaptability:
a. Transmission efficiency: 85%-95% with minimal energy loss
b. Wide reduction ratio range (31-203), adjustable through planetary gear tooth configuration


 Outstanding dynamic performance:
a. Low-vibration design ensures smooth robotic arm operation without end-effector jitter
b. Rapid acceleration response enables high-speed trajectory tracking
