Zero Backlash Hollow Shaft Precision Reducer Gear Rv, Repace Nabtesco Rs-320CA
RV Gear Reducer requirements
RV Reduction Gear, 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.
Market status of RV Gear Reducer
There are two main types of reducers currently used in the field of robots, one is the RV reducer and the other is the harmonic reducer. In the articulated robot, due to the higher rigidity and rotation accuracy of the RV reducer, the RV reducer is generally placed at a heavy load such as the base, the boom, the shoulder, etc., and the harmonic reducer is placed on the arm, wrist or hand. For high - precision robot reducers, Japan has an absolute leading edge.
At present, 75% of the precision reducers in the global robot industry are monopolized by Japan's Nabtesco and HarmonicDrive (commonly known as RV reducers and harmonic reducers in the industry), including ABB, FANUC, The reducers of international mainstream robot manufacturers such as KUKA are provided by the above two companies. Nabtesco's RV reducers account for about 60%, and Harmonica's harmonic reducers account for about 15%.
In 2010, Nantong Zhenkang Welding Electromechanical Co., Ltd.(our cooperative partner) was developed for high - end industrial applications (industrial robots) transmission core components RV reducer and series AC servo motors, and put into mass production, which has been widely recognized in the market.
RV Gear 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 .
RV Gear Reducer application
High - end intelligent equipment industry such as industrial robots, external shafts, precision machine tools, radars, and medical devices.
