Nabtesco RV Series Robot Arm High Precision Gear Reducer

Brief Introduction of Nabtesco RV Series Robot Arm Gigh Precision Gear Reducer
RV reducer is based on the drive of oscillatory transmission, a series gear
branch input multi-synchronous input shaft roller power transmission to ensure
that it covers a high-precision drive, high stiffness, high load
characteristics. The products were patents, patent No.: 97100463.3

Because of its superior performance, roll tooth drive can be widely used in
petrochemical, metallurgical mine, light pharmaceutical, food oil, textile
printing and dyeing, overweight, such as transportation and construction
machinery industry machinery used for deceleration. If necessary, it can also
be used with the growth rate, It is worth mentioning that the roll transmission
gear has extremely carrying capacity, can achieve high-precision, high-
stiffness compound rolling live transmission gear was developed and patents for
invention was accessed. Such precision reducer is particularly applicable to
robots, CNC equipment, aerospace equipment, defense equipment and weapons
requirements of high-precision control of the transmission system.


1. Multi-tooth meshing-High load capacity

2. Simple Structure. No indispensable output institutions as in cycloid reducer

3. High-speed motor can be connected to drive, and this would be benefit to the
requirement of sensitivity of intelligent control system

4. Basically can achieve rolling meshing, transmission with high efficiency.
CORT reducer normally be used in the speed ratio of (i=40~180), the mechanical
efficiency of 80-90%

5. Bigger transmission ratio, compact structure

6. Big output rigidity, slight backlash

7. When do transmission, torque fluctuations less.

Product Test:

The CORT precision trasmission reducer samples which is designed and developed
by our company have been rigorous performance tested. The test include:
Transmission characteristics experimentation, precision and backlash testing,
drive stiffness testing and testing.

The performance test commissioned by the: National Reseach Center of harmonic,
the state keystone industrial harmonic drive base, Beijing Zhongjikemei
Harmonic Drive company LTD: Responsible. It is worthy to note that: The
experimental results show that, CORT reducer precision and backlash are less
than 1 arcmin, and it has reached the international advanced standards.

Application of RV:

1. Stacking
2. Welding
3. Packing
4. Automation equipment
