RV Reduction Gear introduction & development
Compared with the traditional harmonic drive reducer, the RV reduction gear has high fatigue strength, strong rigidity, long service life and stable return accuracy. Unlike harmonic transmission, the motion accuracy will decrease significantly with the use of time. Many high - precision robotic drives in many countries use RV reducers. For the time being, RV reducers have a tendency to gradually replace harmonic reducers in advanced robotic drives.
Nabtesco, Japan: World Speed Reducer
Nabtesco was founded in September 2003. In fact, it is composed of a combination of Teijin Seiki and Nabok. As the world's largest company in the field of precision reducers for industrial robot joints, Nabtesco accounts for 60% of the global market.
The Japanese Teijin Seiki was established in 1944. Around 1980, Teijin Seiki proposed the RV transmission theory and started to apply to the robot industry. In 1986, the Teijin Seiki RV reducer was officially mass - produced and succeeded.
As a manufacturer of motion control systems and components, both companies have mastered high - end core technologies in their specific business areas and controlled a high market share. In 2003, Teijin Seiki and Nabok merged to form Nabtesco, which has developed into a leader in the RV reducer industry, accounting for more than 60% of the market, especially in medium/heavy duty robots, and its RV reducer market. The share is as high as 90%.
In the past 20 years, Nantong Zhenkang has been focusing on the development and production of the core components of precision robots, precision motors and precision RV reducers.
