- Product Description
Harmonic reducers are widely used in various fields such as industrial automation, robot arm joints, humanoid robots, semiconductor LCD production devices, photovoltaic equipment, optical instruments, precision machine tools, etc. due to their high torque capacity, high rigidity, high positioning accuracy, high rotation accuracy, rate, high stability, ultra small size, and weight.
Harmonic drive is a type of power transmission that has many advantages over other transmission methods, such as high transmission ratio, high precision, large load-bearing capacity, high efficiency, small size, and light weight. It is widely used in space technology, electronics industry, military industry, robotics, packaging machinery, printing machinery, medical equipment, and other fields, and has a wide range of application space. We generally refer to it as harmonic reducer or harmonic reducer.
After decades of development, the development of harmonic reducers has also been advancing rapidly, and harmonic transmission technology has become increasingly mature. As one of the main components of harmonic transmission, cross roller bearings have also experienced rapid development in China in recent years. Harmonic drive special cross roller bearings have slightly different structures from ordinary cross roller bearings. The basic structural form is similar, basically using an outer ring segmentation type and an inner ring integral structure. Compared with standard cross roller bearings, there are many installation holes machined on the inner and outer rings, especially the inner ring, which generally has three layers of installation threaded holes of different sizes and quantities from the outside to the inside. This is the difference in appearance from basic cross roller bearings. The material is made of GCr15 bearing steel, and the outer ring is heat-treated with integral quenching process, while the inner ring is heat-treated with high-frequency quenching process on the raceway surface, which is the difference compared to the ordinary cross roller bearing process.
