Harmonic drive is a kind of transmission that relies on the wave ultrasonic generator to make the soft transmission gear cause the controllable ductile deformation wave to maintain the driving force transmission of fitness exercise. The harmonic reducer came out in the US-Soviet market testing period in the last century. The key is to deal with the urgent requirements of the aerospace engineering fitness sports organization for compact structure, light quality, light weight, large transmission ratio, fast transmission speed, and high transmission precision reducer. The basic principle of harmonic gear transmission was first clearly put forward by former Soviet technical engineer A. Mocha Youwekin in 1947, while British C.WaltonMusser invented harmonic reducer in 1953 according to the requirements of indoor space utilization, obtained a U.S. patent in 1955, and exhibited harmonic reducer products in new york City in 1960. Harmonic reducer three pieces In 1961, harmonic speed reduction was introduced into China, and China has just begun to carry out scientific research on the design, manufacturing and application of harmonic reducer. The composition of the harmonic reducer is shown in Figure 1, including the rigid wheel, flexible wheel and wave ultrasonic generator and other three components. Status of scientific research on indoor space harmonic reducer At this stage, the United Kingdom, Japan, France and other major aerospace industry countries have research laboratories and enterprises mainly engaged in indoor space harmonic production and scientific research. More well-known is the HD enterprise, in order to solve the aerospace engineering four-axis aircraft on the use of indoor space harmonic reducer requirements, set up a scientific research unit mainly engaged in indoor space harmonic reducer, and developed and designed a universal aerospace engineering with harmonic reducer. At this stage, HD enterprise has become the most famous manufacturer of harmonic gear transmission in the world, and has carried out the standardization and generalization of harmonic gear transmission. At this stage, the slightly shorter cup model specifications CSD and SHD in the double arc tooth profile products developed by harmonic transmission co., ltd. have a flexspline length of only 1/3 of that of the basic harmonic transmission flexspline, which not only improves the bending stiffness of transmission, but also greatly alleviates the quality of harmonic reducer. Since the 1990 s in the new century, the United States, the Netherlands, France, France, Germany and other European countries have not only applied harmonic transmission in many industries such as intelligent robots and CNC lathes, but also have just begun to carry out scientific research on the design and application of harmonic transmission in indoor space organizations such as communication satellites. Therefore, the United States in the harmonic reducer design, manufacturing, application and indoor space, such as the level of the accumulation of rich and colorful work experience and basic theory of basic The development trend of harmonic drive technology in China can be traced back to the beginning of the 20th century and the beginning of the 60th century. In 1961, the Shanghai Academy of Textile Sciences introduced this technology into our country. At first, it was only used for national defense and aerospace engineering. It was not until the 1980 s in the new century that it slowly began to be civilian. At this stage, the key to the harmonic reducer used in China's aerospace engineering comes from Beijing Zhongji Kemei Enterprise. The harmonic reducer developed and manufactured by this enterprise has long been used in the Shenzhou spacecraft and its "Yutu" lunar rover. Wait for a multi-model specification indoor space quadcopter. The company is at the leading level in China in the development and application of indoor space harmonic reducer. Yutu lunar rover With the rapid development trend of space robots, aerospace engineering, airline four-axis aircraft, and its medical robots and nuclear power plant manufacturing industry, more stringent regulations have been clearly put forward for the application of harmonic reducers, especially in the volume, quality and transmission precision of harmonic reducers. Therefore, the small displacement coefficient of high precision short flexible wheel harmonic reducer is the development trend of harmonic drive.
