In recent years, as long as we talk about harmonic reducers , people in the field of industrial robots will not be unfamiliar. In the past years, this sometimes core component of robots has been occupied by foreign brands for a long time, and the total cost of robots has been about 30%. This reality also objectively pushes up the cost of domestic robotic applications...
The past and present of the harmonic reducer:
In the mid-1950s, with the development of global science and technology, American Mather invented a new harmonic transmission technology based on the theory of thin shell elastic deformation using the principle of flexibility and elastic mechanics of metal. Harmonic transmission technology is mainly used in aerospace, industrial robots, precision equipment, radar communication equipment, printing machinery, textile machinery, semiconductor industry wafer transfer equipment, printing and packaging machinery, medical equipment, metal forming machinery, instrumentation, optical manufacturing. Instruments, nuclear facilities and aerodynamic experimental research.

The emergence of this new technology of harmonic transmission has attracted the attention of all countries. Introduced to Japan in 1970, the birth of Japan's first overall sports control leader - Japan Harmonic Drive Systems Inc. (HDSI). The HarmonicDrive harmonic reducer manufactured by HDSI Corporation of Japan is widely used in various transmission systems due to its light weight, small size, high transmission efficiency, wide deceleration range and high precision. HDSI mainly produces and sells a variety of precision gear units, and is well-deserved as the leader in overall motion control. In order to cover the low reduction ratio field that harmonic reducers cannot cover, HDSI products have also developed the precision planetary gear reducer HarmonicPlanetary. The unique internal ring gear deformation process allows the planetary gears to mesh tighter and eliminate backlash, thus controlling the transmission error within a precise range. HDSI was originally developed only in China, and has long-term cooperation with Yaskawa Electric, Mitsubishi Electric and FANUC.
In recent years, China's industrial robot industry has entered a new historical opportunity period. International robot companies represented by ABB, KUKA, Yaskawa, and FANUC have entered China in a big way, setting up factories and occupying market share. In China, such as mobile phone manufacturing, semiconductor, liquid crystal production machinery and other industries, the demand for small robots is also growing, but for domestic industrial robots, especially harmonic reducers, servo motors , control systems, etc. A large amount of dependence on imports has led to a gap between its competitiveness and foreign companies, but these are the upstream components and key components of industrial robots. According to the International Federation of Robotics (IFR), China imported about 22,000 industrial robots in 2012. China will be the fastest growing industrial robot market in the world . HDSI's harmonic reducer is an irreplaceable component of small industrial robots (below 20kg) or articulated arms, which brings new opportunities for expanding the Chinese mainland market. In January 2011, HDSI established Hamernaco (Shanghai) Trading Co., Ltd. in China, which is a wholly-owned sales subsidiary of its investment in China. Mainly responsible for the technical support and after-sales service of sales, selection and selection of HDSI products in mainland China.
