Cycloidal Gear Reducer Drive Heavy Load 2 Stage Reduction RV-320e Nabtesco
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.
Cycloidal Gear reducer widely used in the field of industrial robot , SCARA, positioning axis , AGV, machine tool, medical equipment , indexing mechanism, rotary table, elevator platform , wind energy mechanism , gantry , aeronautics .
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 the past 20 years, we has been focusing on the development and production of the core components of precision robots, precision motors and precision RV reducers.
We has successfully developed RV reducers for robots under 300 kg, with a total of 17 products.
