Introduction of RV reducer

The RV reducer is developed on the basis of the traditional cycloid planetary transmission,and it consists of cycloidal-pin wheel and planetary rack. It not only overcomes the drawback of cycloid drive,but also has a series of advantages such as small volume, light weight, large range of transmission ratio, long service life, stable precision, high efficiency, smooth transmission which is widely used in industrial robots, machine tools, medical testing equipment, satellite receiving system and other fields.RV reducer is one of thekey components needed for robot joints, and it accounts for about 40% of the cost of the robot, therefore, its performance directly affects the repeat positioning accuracy, stability and reliability of the robot. It has higher fatigue strength, stiffness and longevity compared with the harmonic drive which is commonly used in robot, besides its backlash accuracy is stable, not like the harmonic drive that the movement accuracy could be significantly reduced as time goes on. Therefore, the RV reducer is massively used in advanced robot driving.

Product feature

1）  wide range of gear ratio

2） highTorsional rigidity, the output mechanism is planet carrier which is supported at both ends, using the rigid big disc at the left of the planet carrier to output, the big disc is bolted with the working mechanism，and its torsional rigidity is higher than the output mechanism of general Pin-cycloidal gear planetary reducer，with fewer elastic return difference under the nominal torque

3）  Transmission efficiency

4）  The bearing capacity of unit volume is small. The first level of RV reducer using three planetary wheel, the hard surface gear of cycloidal-pin wheel of the second level is multi-teeth meshing, this determines that it can transfer bigger torque with small volume; besides, in the process of structural design, the driving mechanism is put in the base bearing of the planetary carrier to narrow the axial size so that the volume is small when transmit the same torque and power.

Guide for selection

First of all, determining the working condition of coefficient according to the load condition before determine the output torque,and then choosing the reduction ratio and model size,at last, determining the specific specifications and performance ratio.
