As one of the three core components of the robot, the reducer has been deeply concerned by the development of China. Nowadays, under the rise of a number of domestic enterprises, the development of China's reducer is accelerating, and the breakout is expected!
As we all know, the reducer is a kind of reduction gear in modern machinery, which mainly plays the role of matching the speed and transmitting torque. In the robot industry that has been rapidly emerging and developing in recent years, the speed reducer is not only considered to be one of the most important components of the robot, but also considered to be the key to the breakthrough development of the industry.
But in fact, for industrial robots, its own speed control function can also be realized by the power source servo motor. Why is it so important to look at the speed reducer? That is because, due to the particularity of repeated operations of industrial robots, it has high speed positioning requirements with high positioning and repeated positioning accuracy. This is obviously not satisfied by the servo motor that provides power, so it must rely on the reducer to provide accuracy. Effective protection of the work.
In addition, the reducer also plays the role of transmitting torque in the industrial robot. On the one hand, it can release the load pressure by itself to reduce the power loss of the servo motor; on the other hand, it can maintain a suitable and stable speed operation to ensure long-term, Periodic robot work accuracy.
Based on the above functions and advantages, the reducer has always been regarded as the focus of the development of the robot industry by various countries. China also regards the reducer as the key to the rise of the robot industry. Therefore, in recent years, with the vigorous development of industrial robots, the actual demand for speed reducers for robots in China has also ushered in a rapid rise.
Opportunities and challenges in China's market
At present, the reduction gears for robots can be roughly divided into five categories according to their structure. Among them, RV reducers and harmonic reducers are the most mainstream. The former is suitable for medium and heavy-duty industrial robots, while the latter is mainly used for light industrial robots or robotic arms. Above.
In the development of these two types of main reducers, the overall size of China's market in 2017 was about 3.7 billion yuan, and the RV reducer and harmonic deceleration accounted for 2 billion yuan and 1.7 billion yuan. The overall market development is relatively good. At the same time, under the blessing of an average annual growth rate of 18%, it is estimated that the domestic scale will exceed 6 billion yuan in 2020, and the development potential is enormous.
However, under the good market development, the domestic reducer is not smooth sailing. Despite the strong demand for automation, the maturity of the robot industry, the growth of the reducer market, and the support of government policy dividends, it has brought development opportunities to domestic reducers; but at the same time, domestic products are in technology, brand and market share. The weakness also makes the development of China's reducer face a severe challenge.
Today, China's reducer market is basically monopolized by foreign companies headed by Nabtesco and Hamernaco. Their products account for more than half of the domestic market share, and the core technology of the reducer is firmly controlled by them. Even if we look at the world, the two companies have an absolute advantage. They have made it difficult for Chinese companies to turn over with the remarkable strength of the industry.
It is gratifying that the enthusiasm of Chinese enterprises has not been ruined. In recent years, China has also emerged as a group of powerful enterprises. Among them, in the field of harmonic reducer, the emergence of Wuxi Green, Dongguan Benrun and other companies, in one fell swoop close the technical gap between domestic and foreign harmonic reducer, domestic products in the performance of the basic pursuit of catching up and beyond;
In the field of RV reducers, although the technical difficulties have been delayed, domestic products still have fatal defects such as poor performance, fast heating, high noise and short life, but Nantong Zhenkang, Qinchuan Machine Tool, Wuhan Essence, Zhejiang Hengfeng Taihe The rise of Zhejiang Shuanghuan Transmission and other enterprises also blew the horn of domestic brands counterattack!
What is the way out for domestic reducers?
Of course, China can make a significant breakthrough in harmonic reducer. On the one hand, the patents of related companies that have mastered the core technology have expired, the technical restrictions have been relaxed, and on the other hand, the structure of the harmonic reducer is relatively simple. The difficulty is not that big, but the RV reducer is not the case.
Due to the deadlock of the RV reducer technology, the basic process and structure are more complicated, and there is no shortcut to walk. It can only rely on time to grind. Therefore, the RV reducer is undoubtedly the main difficulty in the breakthrough of China's reducer. At the same time, according to industry insiders, industrial robots are developing in a light and small direction. Although this has a certain driving effect on the growth of harmonic reducers, it is undoubtedly a difficult situation for China's RV reducers. .
So, where is the way out for China's RV reducer in the future? The author believes that it is necessary to explore and find out from three aspects. First of all, we must continue to expand production capacity, increase the production capacity of enterprises and increase the mass production of products, which will highlight the price advantage of domestic enterprises. If foreign companies are trapped by the delivery cycle and supply cycle, if Chinese enterprises can solve the capacity problem, It will have a serious impact on foreign brands.
The second is to insist on technical research. The technology of RV reducer is a long-term, high-input, slow-reward, and heavy-capital process. Even today's giant companies rely on the accumulation of time to achieve extraordinary achievements. Therefore, Chinese enterprises must have patience, persistence, conviction and craftsmanship, and we can achieve results step by step.
Finally, it is necessary to play a spirit of collaborative innovation. RV is an industry direction from a model, relying not only on the independent strength of Nabtesco, but also the support of all enterprises in the entire industry. Therefore, Chinese enterprises should also play a spirit of collaborative innovation, and form an industry synergy through strong alliances, cooperation and exchanges to achieve an effective breakthrough in the development of corporate issues.
