Reducer of core components of palletizing robot

In the last article, we talked about the servo system of the palletizing robot. Today, we will continue to talk about another core component of the palletizing robot: the reducer. In the global market, the reducer is monopolized by Japanese enterprises by 85%.

According to the report (the industrial robot industry chain is at the bottom, and domestic brands are rising in the big wave), precision reducer manufacturing has high investment, high technical difficulty and high barriers. As a result, the global market for industrial robot reducers is highly concentrated, with nabotsk of Japan having a monopoly in the field of RV reducers and harmonaco of Japan having a monopoly in the field of harmonic reducers. The two together account for about 75% of the global market, while Sumitomo, a Japanese manufacturer, accounts for 10%. Due to its extremely high technical barriers, the bargaining power of the palletizing robot body manufacturing link to the reducer link is very weak.

RV Reducer, as a reducer with small volume, large transmission ratio, zero backlash and ultra-high transmission / volume ratio, is a pinnacle of the precision machinery industry. The reducer is completely composed of high-precision components and gears meshing with each other, which puts forward high requirements for material science, precision processing equipment, processing accuracy, assembly technology and high-precision detection technology.

The technical feature of Naboo RV Reducer is that it can not only withstand great impact, but also ensure the transmission and accuracy of large torque. Therefore, the requirements for materials, heat treatment, grinding, bearings, assembly and testing are very high. When the reducers of many domestic manufacturers first leave the factory, the accuracy may meet the requirements, or even exceed the accuracy required by the robot movement, but after running for more than a certain time, the accuracy drops greatly and cannot meet the use requirements. Therefore, although many domestic manufacturers have developed and produced reducers, they have no competitive advantage.

As an essential transmission equipment in the modernization construction, reducer is applied in various industries. Taking the palletizing robot industry as an example, with the rise of human resource costs, the demand for reducers will also increase significantly.
