Cycloidal Gear Speed Reducer Motor Multiteeth Contact, Nabtesco Rv-320CA
Cycloidal gear speed reducer 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.
As a small volume, large transmission ratio, zero backlash, ultra - high transmission / volume ratio reducer, is the pinnacle of the precision machinery industry, the gearbox is completely made of high - precision components, gears mutual engagement, puts high demands on materials science, precision machining equipment, machining accuracy, assembly technology, and high - precision inspection technology.
Widely use in the high - end intelligent equipment industry such as industrial robots, external shafts, precision machine tools, radars, and medical devices.
In the field of global industrial robot core components, the Japanese reducer brand Nabtesco has long occupied 60% to 80% of the international market share of precision reducers for industrial robots. We have developed an RV gearbox that can replace the Japan Nabtesco reducer.
Cycloidal Gear Speed Reducer features
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, long working life .
