    Unique RV Gear Reducer , Cyclo Gear Reducer Support External Loads

    VIGO Drive RV-E CYCLOIDAL Gear Reducer RV-20E-121, High Stiffness RV Gear Reducer


    Type of RV gear reducer


    There are two main types of reducers that are widely used on articulated industrial robots: RV reducers and harmonic reducers. Compared to harmonic reducers, RV reducers have higher stiffness and rotational accuracy. Therefore, in an articulated industrial robot, the RV reducer is generally placed at a heavy load such as a base, a boom or a shoulder; and the harmonic reducer is placed at the arm, wrist or hand; the planetary reducer is generally Used on Cartesian industrial robots.


    At the same time, the RV reducer has much higher fatigue strength, stiffness and life than the harmonic drive commonly used in industrial robots, and the hysteresis accuracy is stable. Unlike the harmonic drive, the motion accuracy will be significantly reduced with the use of time. Therefore, many high-precision industrial robot transmissions in many countries in the world use RV reducers. Therefore, this kind of RV reducer has gradually replaced the development of harmonic reducers in advanced industrial robot transmission.


    Working principle of RV gear reducer


    The RV drive is a new type of transmission developed on the basis of cycloidal pinwheel drives.The RV reducer consists of an involute cylindrical gear planetary reduction mechanism and a cycloidal pinion planetary reduction mechanism.The involute planetary gear is integrated with the crankshaft as an input to the cycloidal pinion drive section.The crankshaft drives the cycloidal wheel for eccentric motion.The crank rotates clockwise clockwise for 1 week and the cycloidal wheel moves 1 tooth counterclockwise.The core components of the RV reducer are the pin housing, the crank shaft and the cycloidal wheel.


    Features of RV gear reducer


    1. Less than 1 arc - min Backlash
    2. Strong impact resistance
    3. Very compact with high torsional rigidity
    4. Component in - line version for greater design and space saving flexibility
    5. Large transmission ratio range
    6. High transmission efficiency
    7. Long working life
