What is the difference between planetary reducer, RV reducer and harmonic reducer? 1. planetary reducer is an industrial product. Planetary reducer is a transmission mechanism. Its structure is closely combined with an internal gear ring on the gear box housing. The center of the ring gear has a sun gear driven by external power. Between the two, there is a group of planetary gear sets composed of three gears on the tray, this group of planetary gears relies on the output shaft, internal gear ring and sun gear support to float during the period. When the power on the input side drives the sun gear, it can drive the planetary gear to rotate and follow the trajectory of the internal gear ring to revolve along the center. The rotation of the planet drives the output shaft connected to the tray to output power. A mechanism that uses a gear speed converter to reduce the number of revolutions of the motor (motor) to the desired number of revolutions and obtain a larger torque. In the reducer mechanism used to transmit power and motion, the planetary reducer is a precision reducer, such as PGM planetary reducer of Shenzhen Dongma Electromechanical, Hubei planetary reducer, etc. The reduction ratio can be accurate to 0.1 rpm -0.5 r/min minutes. 2. RV transmission is a new type of transmission. It is developed on the basis of traditional needle pendulum planetary transmission. It not only overcomes the shortcomings of general needle pendulum transmission, but also has a series of advantages such as small size, light weight, large transmission ratio range, long service life, stable precision, high efficiency, stable transmission and so on. increasingly widespread concern at home and abroad. RV reducer is composed of cycloid pin wheel and planetary bracket with its small size, strong impact resistance, large torque, high positioning accuracy, small vibration, large reduction ratio and many other advantages are widely used in industrial robots, machine tools, medical testing equipment, satellite receiving systems and other fields. Compared with the harmonic drive commonly used in robots, it has much higher fatigue strength, stiffness and life, and the return difference accuracy is stable. Unlike harmonic drive, the movement accuracy will be significantly reduced with the increase of use time. Therefore, RV reducer is mostly used in high-precision robot drive in many countries in the world. Therefore, this kind of RV reducer has the development trend of gradually replacing harmonic reducer in advanced robot drive. 3. harmonic reducer is mainly composed of three basic components: wave generator, flexible gear and rigid gear. Harmonic transmission reducer is a kind of controllable elastic deformation of flexible gear by wave generator and meshing with rigid gear to transmit motion and power. Planetary reducer, RV reducer, and harmonic reducer have different working principles, different transmission methods, and different application industries
