Development And History of Harmonic Reducer

The development and history of harmonic reducer can be traced back to the 1940s. At that time, the former Soviet Union first proposed the transmission device using mechanical waves to control the elastic deformation of flexible components to achieve the transmission and conversion of motion and torque, and in 1947 produced the world's first harmonic friction transmission principle using harmonic transmission. In 1955, the United States proposed the concept design of harmonic gear transmission mechanism, and obtained patent authorization in 1959. Since then, harmonic gear transmission technology has been rapidly promoted in the former Soviet Union, the United States and other industrial developed countries, and has been introduced into practical development by Japan.

With the continuous progress of science and technology and the continuous upgrading of industrial demand, harmonic reducer has been widely used in robot, precision machining equipment, aerospace, radar equipment, medical equipment and other fields. In recent years, the global robot industry has developed rapidly, and the output of industrial robots and service robots has been increasing, making the demand for harmonic reducer in the robot industry continue to increase. In addition, harmonic reducer in addition to the robot precision transmission field can also be widely used, the application industry is expanding to high-end CNC machine tools, semiconductor manufacturing equipment, medical equipment and other fields.

In China, the research and production of harmonic reducer has also made great progress. Since the 1960s, China has begun the development of harmonics. In recent years, with the rapid development of robotics and other industries, China's speed reducer market has exceeded 2 billion yuan, of which harmonic speed reducer occupies an important share. At the same time, China's aerospace industry is also carrying out scientific research and application development of indoor space harmonic reducer.
