Couplings are widely used, including equipment matching and user maintenance and replacement, which shows a good situation in terms of usage.In modern industry, most general power machines are connected with working machines by means of couplings.
Plum-shaped elastic couplings are mainly suitable for frequent starting, forward and reverse rotation, medium and high speed, medium torque and high reliability work occasions, such as: metallurgy, mining, petroleum, chemical, lifting, transportation, light industry, textile, Water pumps, fans, etc.
Related government policies play a very important role in promoting the development of the coupling industry.From an international point of view, the coupling industry of all countries received strong support from the government in the early stages of development.
Coupling is a mechanical element that connects the drive shaft and the driven shaft of the mechanical system, and is used to transmit power. It is used by almost all manufacturing machinery.Its basic function is to absorb the eccentricity, deflection angle and axial displacement error of the two shafts, and to transmit power smoothly.
Rigid coupling: It can only transmit motion and torque. There are several failures of drum gear couplings and their causes. It does not have other functions, including flange coupling, sleeve coupling, and clamp coupling The calculation of the coupling and the function of the two types.
After decades of development, the coupling industry in my country has made considerable progress in terms of quantity, quality and technology. The progress is also very great.However, compared with the needs of national economic development and the world level, there is still a certain gap.
Proximal couplings are more and more used in machine tools and semiconductor system manufacturing machinery, which are controlled by servo systems.In these fields, unlike general manufacturing machinery, the coupling requires a high degree of followability of its output relative to its input.
