RV transmission is a newly emerging type of transmission, developed based on the traditional cycloidal planetary transmission. It not only overcomes the shortcomings of conventional cycloidal transmissions but also offers a range of advantages, including compact size, light weight, a wide transmission ratio range, long life, stable accuracy, high efficiency, and smooth transmission. It is gaining increasing attention both domestically and internationally. Composed of a cycloidal pinion and a planetary carrier, the RV reducer boasts numerous advantages, including compact size, strong impact resistance, high torque, high positioning accuracy, low vibration, and a large reduction ratio. It is widely used in industrial robots, machine tools, medical testing equipment, satellite reception systems, and other fields. Compared to the harmonic drive commonly used in robotics, it offers significantly higher fatigue strength, stiffness, and lifespan. Furthermore, it offers stable backlash accuracy, unlike harmonic drives, which experience significant degradation in motion accuracy over time. Therefore, many countries around the world use RV reducers for high-precision robotic transmissions. Consequently, this type of RV reducer is poised to gradually replace harmonic reducers in advanced robotic transmissions.
