Nabtesco Cycloidal Gearbox Reducer Rv-20E , Cyclo Drive Speed Reducer Small Size Large Deceleration Ratio
Cycloidal Gear Reducer as one of the core technology of robot, the cost occupies about 40% of the whole robot, our RV gearbox small size, large deceleration ratio, low working inertia, small noise, high torsion rigidity, high impact load capacity (can withstand 5 times the rated torque), high working accuracy (tooth gap less than 1arcmin), long service life. We have the most perfect RV reducer comprehensive performance test platform, which can quickly and effectively measure the RV gearbox tooth gap accuracy, transmission accuracy, efficiency, noise, stiffness, vibration and other properties.
The production of Cycloidal Gear Reducer must go through the gear
gap accuracy, noise and stiffness detection, in line with
enterprise standards of products can be delivered.
