Introduction The Standard RV Reducer E Series is a precision reduction device featuring a two-stage closed differential gear system composed of a cycloid pinwheel and planetary gears, with a solid output shaft. It is widely used in industrial robotics applications. For robotic arms with end loads ≤20 kg, RV reducers are primarily employed in base-to-high-load joints (typically Joints 1-4). For robotic arms with end loads >20 kg, all six joints typically utilize RV reducers. RV reducers serve as the core transmission component ensuring robotic arm positioning accuracy. Features ● Solid Output Shaft Enables direct load coupling and provides enhanced sealing convenience. ● Two-Stage Reduction Design First Stage: Involute planetary gear transmission for initial speed reduction. Second Stage: Cycloid pinwheel transmission for further speed reduction and torque stabilization. ● High Rigidity & Impact Resistance Rigid disc support at the output ensures uniform load distribution, minimizing deformation. Multi-crank shafts combined with high-precision bearings effectively disperse stress impacts. ● Compact Enclosed Structure The transmission mechanism is integrated within the planetary carrier support bearings, significantly reducing axial dimensions. Advantages ● High Load Capacity & Precision Torque range: 50–7000 N·m, suitable for heavy-duty robotic arms (e.g., welding, material handling robots). Backlash precision: <1 arcmin, with minimal repeat positioning error. ● Long Lifespan & High Reliability Multi-tooth meshing (≥30 teeth) ensures even wear distribution, extending service life to 6,000–10,000 hours. Superior fatigue resistance compared to harmonic drives, making it ideal for 24/7 continuous operation. ● High Efficiency & Adaptability Transmission efficiency: 85%–95%, minimizing energy loss. Wide reduction ratio range (31–203), adjustable via planetary gear teeth configuration. ● Exceptional Dynamic Performance Low-vibration design guarantees smooth robotic arm operation, eliminating end-effector jitter.
