High Torsional Stiffness RV Reduction Gear Minimal Abrasion, Same Qualtiy Nabtesco Reducer RV-50C
RV Reduction Gear important role
RV transmission is a brand - new transmission method. It is
developed on the basis of the traditional oscillating planetary
transmission. It not only overcomes the shortcomings of the general
swaying transmission, but also has a small size, light weight,
large transmission ratio range and long service life. A series of
advantages such as stable accuracy, high efficiency and smooth
transmission.
The presence of the rv reducer allows the servo motor to operate at
a suitable speed and accurately reduces the speed to the speed
required by various parts of the industrial robot, increasing the
rigidity of the machine while outputting greater torque. Compared
with universal reducers, industrial robot joint reducers require
short drive chains, small size, high power, light weight and easy
control.
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.
Nantong Zhenkang has successfully developed RV reducers for robots
under 300 kg, with a total of 17 products.
