Improve component design and strengthen manufacturing of high-quality couplings

in the manufacturing industry, parts occupy an important position in manufacturing equipment. These small parts are like blood vessels connecting people's hearts. Although they are light, they play a role in connectivity. Among them, the coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of cushioning, damping and improving the dynamic performance of shafting. With the development of science and technology in recent years and the improvement of manufacturing industry's requirements for precision production, the construction of coupling also needs to move towards the direction of national high standards

according to insiders, standard manufacturing refers to manufacturing according to national standards, while enhanced manufacturing refers to manufacturing superior to national standards. The product quality of the two is different. For couplings, whether rigid or elastic, most of them have clear strength performance indicators such as structural shape and size and nominal torque of the coupling, which is the standard basis for coupling manufacturers to manufacture couplings. However, the quality of the coupling will be different if the position of the nominal torque of the coupling in the field of lithium battery and lithium battery recovery is different

experts say that the nominal torque of the coupling is reflected in the coupling accessories, and the strength of the two halves of the coupling is equal to or lower than the strength of the coupling accessories, which will lead to the early scrapping and failure of the two halves of the coupling (due to the reciprocating start and stop or a little overload of the transmission system); The intensified manufacturing of coupling means that while the coupling accessories reflect the nominal torque, the strength of the two halves of the coupling is higher than that of the coupling accessories, which is an effective means to improve the quality of the coupling. The improvement of this quality often leads to the dynamic setting of the coupling, the working mode and operating parameters of the friction tester, and the manufacturing cost increases, resulting in the high price of the coupling, which makes it difficult for the coupling users to accept, The latter is mainly from corn or other sugar containing crops (such as cassava). The competition node should be the matching state between the strength of the two halves of the coupling and the overall performance of the specific transmission equipment

for example, the material standards of the two halves of the drum gear coupling include 45# steel, 42CrMo steel and 40Cr steel, and the corresponding heat treatment includes quenching and tempering treatment, nitriding treatment, etc. the manufacturing cost of the coupling is different, the price of the corresponding coupling is also different, and the quality of the coupling is different, This requires professional coupling manufacturers to communicate with coupling users to optimize the design and manufacture. The same situation also exists in other rigid or elastic couplings, such as cast steel and forging materials of diaphragm coupling and corresponding quenching and tempering treatment. This is the difference in quality and price between standard manufacturing and enhanced manufacturing of couplings, and it is also the reason for the expansion of the scope of coupling accessories

it is understood that the diaphragm coupling is a high-performance flexible coupling with metal elastic elements. It relies on the elastic deformation of the diaphragm to compensate the relative displacement of the two connected shafts. It does not need lubrication. It has compact structure, high strength, long service life, no rotation clearance, and is not affected by temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance and anti-corrosion. It is suitable for the shafting transmission in the working environment of high temperature, high speed and corrosive medium. It is widely used in the shafting transmission of various mechanical devices, such as water pumps (especially high-power and chemical pumps), fans Compressor, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), ship high-speed power transmission system

the author learned that the JZM diaphragm coupling for heavy machinery developed by Botou Yuze Machinery Manufacturing Co., Ltd. has the characteristics of high mechanical strength, large bearing capacity, light weight, small structural size, high transmission efficiency and transmission accuracy, good reliability, convenient assembly and disassembly, no relative sliding, no lubrication, long service life, no noise, acid, alkali resistance and corrosion resistance. It can be used in high temperature, low temperature and oil Working environment with water and corrosive medium. It is suitable for medium, high speed and high torque shafting transmission. And the shafting transmission with little change in the load of various mechanical devices, which has strong universality

as China's manufacturing industry is gradually moving towards "high precision", the coupling equipment, as an important member, also needs to be synchronized. Relevant manufacturing enterprises should show "craftsman spirit" and take seriously the production and testing management of equipment quality. Promote China's manufacturing industry to further fulfill the made in China dream
