Electric Motor Cycloidal Gearbox Reducer Stable Accuracy Transmission, Nabtesco RV-40E
Cycloidal Gearbox Reducer is the most rigid low - vibration reducer in industrial
robots (mainly spraying, spot welding, arc welding, handling and
assembly robots). It is very beneficial to improve the motion
accuracy and dynamic characteristics of industrial robots. It is
also the core component of industrial robot transmission.
It has a series of advantages such as small size, light weight,
large transmission ratio range, long service life, stable accuracy,
high efficiency and stable transmission.
Industrial robots use RV reducers from the first joint to the
fourth joint. RV reducers are required for all joints of heavy -
duty industrial robots. On average, each industrial robot uses 4.5
RV reducers. At present, 75% of the precision reducers in the
global robot industry are monopolized by Japan's Nabtesco and
HarmonicDrive.
Zhenkang was founded in 1993. It started with the wire feeder of
electric welding machine. It is a manufacturer that has been
involved in RV gearbox for robots earlier in China, currently
we have RV gearbox E series RV-20E, RV-40E , RV-80E,
RV-110E, RV-160E, RV-320E, RV-450E and C series RV-10C, RV-27C,
RV-50C, RV-100C, RV-120C, RV-200C, RV-320C, RV-320CA.
