In the Chinese robot industry has been valued as a key component of the reducer, and the core components in today's world market is monopolized by foreign enterprises, domestic robots are also facing this problem at this stage is always awkward, robot reducer Market Monopoly, the popularity of domestic reducer can not achieve full import substitution. The reducer is used to precisely control robot movements and to transmit greater torque. There are two kinds of RV reducers installed in heavy load positions such as stand, big arm and shoulder, and harmonic reducer installed in light load position such as small arm, wrist or hand. RV reducer by Japan nabtesco monopoly, Japan Hamonake dominant harmonic reducer.

The harmonic reducer structure is relatively simple, only three basic parts, plus Hamonake patent has expired, the domestic harmonic reducer is not large compared to the gap with foreign countries. Suzhou green harmonic reducer has been widely used in domestic robots.

From the size of the market, according to the 2020 robot fleet of 800 thousand units, namely the increment of about 600 thousand Taiwan dollars, a multi joint industrial robot according to the different needs of a number of 4-6 shaft reducer, taking the median of 5, you need 3 million reducer. Optimistic estimates, domestic enterprises to get 50% of the market share, a single reducer 4000 yuan calculation, the scale of 6 billion yuan, on the count, the replacement demand will not exceed 7 billion yuan.

Therefore, our domestic companies more access to the value of the speed reducer, speed reducer Co. Ltd. Zhejiang Fu harmonic Mr. Zhang Jie received us, is a very young entrepreneur, to some extent, he is more like a researcher proficient in technology, began to speak off the reel, talk about reducer Market and Industry Amidst the winds of change. Familiar. And the idea of conversion is very fast, the domestic reducer the price range, market share, industry application and supporting peripheral products, can be a very detailed list clearly, what things can be done, what to do in the future, what things are not afraid to do, he talks very calm, it seems no industry in the traditional ideological baggage.

At present, China annual market sales of industrial robots isabout 70 thousand, but the market share may not be domestic harmonic reducer possession, of course RV reducer together the world situation is not very realistic, in accordance with the robot in the factory work 16 hours a day to count, the accuracy of life ontology robot at home is hard to reach 2 years. At this time, there are many reasons for the robot body to find the accuracy loss of the robot. There are many reasons. The servo motor, the control system and the reducer are likely to have problems. Most of the body manufacturers will consider the harmonic reducer wear problems. Because the use of 2 years, more than 10 thousand of the use of long, harmonic reducer more or less wear phenomenon, this can not be avoided. This is also the problem of domestic reducer manufacturers have been trying to overcome, to overcome the harmonic reducer life problems, this is also the Japanese harmonic drive company has been studying the problem. The characteristics of harmonic reducer are large reduction ratio and large rigidity. The difference between our reducer and the foreign reducer is that in the material aspect, the foreign reducer has already realized the material lightweight, they used the new material is three kinds of metal materials, alloy, it is difficult to analyze. The reducer for steel used in domestic reducers is essentially steel. The density of the metal will not change, even if the punch is not changed, the weight will be changed a lot. The core parts of the robot are lightweight, and foreign countries are in front of us. As with material, reducer manufacturers foreign transmission efficiency, load test, loss and so on have detailed test data as the research basis, this can be seen from HD Company of Japan's album accumulation of their R & D strength and technology, this is our domestic reducer manufacturers need time to accumulate, not just investment the equipment can be done. Precision, material and technology are different from those of foreign reducer. However, in the non-standard machinery field, the domestic harmonic reducer is still relatively stable performance. This is a relief.
