RV gearbox transmission is a newly emerging kind of transmission, which is developed on the basis of traditional pin-pendulum planetary transmission. It not only overcomes the disadvantages of general pin-pendulum transmission, but also has a series of advantages such as small volume, light weight, large transmission ratio range, long life, stable accuracy, high efficiency and stable transmission.More and more attention has been paid all over the world.
FHT RV gearbox reducer is composed of the front stage of a planetary gear reducer and the rear stage of a cycloidal needle wheel reducer. With compact structure, high transmission ratio and self-locking transmission mechanism under certain conditions, the RV reducer is one of the most commonly used reducers, with low vibration, low noise and low energy consumption.FHT RV gearbox for robot joints has five series:RV-C,RV-E,RVM,FHD and FHA.
This RV reduction gear design has advantages in rigidity and resistance against overload with a compact body due to a large number of simultaneously engaged gear teeth. Furthermore, minimal backlash, rotational vibration and low inertia lead to rapid acceleration, smooth motion and accurate positioning.So it is widely used for industrial robots(robot joints), machine tools, semi-conductor,medical testing equipment, satellite reception systems and other large load areas.
RV gearbox has much higher fatigue strength, stiffness and life than harmonic drive.RV gearbox precision of retraction is stable,the motion accuracy does not decrease significantly with use time growth.So many countries in the world adopt RV gearbox reducer for high precision robot transmission.
