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.

Noise & lifetime

1. The gear unit is operated at rated speed with a noise of < 75 dB.
2. The noise level is related to installation accuracy, lubrication, temperature, load and other factors.
3. The reducer operates at rated conditions with a life of > 6000 hours.
4. It is not advisable to operate for longer than the rated speed or rated torque, otherwise the life will be reduced.
5. In order to ensure the accuracy and longevity of the reducer, please change the grease after every 2000 hours of operation.

Features of Cycloidal Gearbox Reducer

Less than 1 arc - min Backlash, strong impact resistance, very compact with high torsional rigidity, component in - line version for greater design and space saving flexibility, large transmission ratio range, high transmission efficiency and long working life.

    Shanghai Genius Industrial Co.,Ltd is the branch of Nantong Zhenkang Machinery Co.,Ltd, which founded in 1993, with 30 years of experience in the production of CO2 welding wire feeder, nowadays we occupy 70% Chinese market and 50% global market for wire feeder, long partners of PANASONIC and OTC Daihen.

    In 2009, we started R&D high precison RV reduction gearbox, this is core part of industrial robots, through 4 years research and development, in 2013, our high precision RV reduction gearbox start bulk production. Nowadays we become China biggest RV reduction gearbox manufacturer, realized robotic automatically produce RV reduction gearbox, also we are supplier of world famous company ABB, FNUC, YASKAWA for gearbox.

    As had advantage of wire feeder and RV gear reducer, with accumulated years of welding experience, we decide to R&D welding robot, After more than one year testing, our welding robot developed successfully in 2016, much earlier than other robot manufacturers in China, now our robot already in market for 5 years, still work well, got good comments from customers.
