Two, RV transmission is a newly emerging transmission, it is in the traditional needle-pendulum planetary transmission developed on the basis of not only overcomes the shortcomings of the general needle-pendulum transmission, but also because of the small size, light weight, large range of transmission ratios, long service life, precision and stability, high efficiency, smooth transmission, and a series of advantages. RV reducer is composed of cycloid pinwheel and planetary bracket, which is widely used in industrial robots, machine tools, medical testing equipment, satellite receiving system and other fields for its small size, strong impact resistance, high torque, high positioning accuracy, low vibration, large reduction ratio and many other advantages. It... A planetary reducer is an industrial product, planetary reducer is a conveyor mechanism, its structure consists of an internal gear ring closely combined in the gear box shell, ring tooth center has a sun gear driven from external power, between the two there is a group of three gears equal combination of planetary gears on the pallet of the group, the group of planetary gears rely on the output shaft, the internal gear ring and the sun gear to support the floating in the period; when the incoming side of the power to drive the sun gear, it can drive the sun gear to drive the sun gear. When the sun gear is driven by the power, it can drive the planetary gears to rotate and follow the trajectory of the inner gear ring to rotate along the center, and the rotation of the planets will drive the output power from the output shaft connected to the pallet. The speed converter of the gear is used to decelerate the number of revolutions of the motor to the desired number of revolutions and to obtain a large torque. Among the gearheads used to transmit power and motion, planetary gearheads are precision gearheads, such as the PGM planetary gearheads of Shenzhen Dongma Electromechanical, Hubei planetary gearheads, etc. The reduction ratio can be as accurate as 0.1 to 0.5mm. The reduction ratio can be accurate to 0.1 rpm-0.5 rpm.

It is more commonly used in robotics harmonic drive has much higher fatigue strength, stiffness and life, and the return precision is stable, unlike the harmonic drive as with the use of time to increase the accuracy of the movement will be significantly reduced, so the world's high-precision robot drive more RV reducer, therefore, the RV reducer in the advanced robot drive gradually replace the development trend of the harmonic reducer
Three, harmonic reducer mainly by the wave generator, flexible gears and rigid gears three basic components, harmonic drive reducer, is a wave generator to make flexible gears to produce controllable elastic deformation, and with the rigid gears to mesh to transfer the movement and power of the gear transmission.
Planetary reducer, RV reducer, harmonic reducer working principle is different, the transmission mode is also different, the application industry also makes a difference.
