Information
In the previous article, we talked about the servo system of the palletizing robot. Today, we continue to talk about another core component of the robot: the reducer. In the global market, the reducer is monopolized by Japanese companies with an 85% share.
 
According to the report (the industrial robot industry chain has a big bottom, domestic brands have risen in the big wave), precision reducer manufacturing, large investment, high technical difficulty, and high barriers. For this reason, the global industrial robot reducer market is highly concentrated, among which Nabtesco has a monopoly position in the field of RV reducer, and Hamernaco of Japan has a monopoly position in the field of harmonic reducer, which together account for the global total. About 75% of the market, another Japanese manufacturer Sumitomo accounted for 10%. Due to its extremely high technical barriers, the bar code robot body manufacturing process has a weak bargaining power for the reducer link.
 
RV reducer, 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 composed 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.
 
The technical characteristics of Nabo's RV reducers are that they can withstand large impacts and ensure high torque transmission and accuracy. Therefore, the requirements for materials, heat treatment, grinding, bearing, assembly and testing are very high. Many domestic manufacturers of speed reducers may meet the requirements when they leave the factory, even exceeding the accuracy required for robot movement. However, after running for more than a certain period of time, the accuracy is very severe and cannot meet the requirements for use. Therefore, although many manufacturers in China have developed and produced reducers, they have no competitive advantage.
 
As an indispensable transmission equipment in modern construction, the reducer is used in various industries. Taking the palletizing robot industry as an example, as the cost of human resources increases, the demand for speed reducers will also increase significantly.
