The working principle and characteristics of elastic coupling

    Flexible couplingPrinciple: The device mainly transmits the torque produced by the prime mover to the driven mover.It can compensate the axial, radial and angular deviations between the prime mover and the driven mover due to manufacturing errors, installation errors, deformation after loading, and temperature changes.Utilize the elastic function of the diaphragm (or elastic body) to undertake the torque transmission of connecting the main and the driven motor; to compensate for the three-way displacement of the two axes, and to absorb and isolate the vibration.Among them, the backlash-free elastic coupling is more superior: it has the characteristics of small structure size, light weight, large transmission torque and high precision.It can more effectively improve the quality and stability of the transmission machinery.
    Flexible couplingThe main features:
1. The flexible coupling has a wide application range, especially suitable for medium, high speed and high power.
2. The flexible coupling is easy to install, use and maintain, has a long service life and a simple structure.
3. The elastic coupling can work under high temperature below 300℃ and corrosive occasions.
4. The elastic coupling can compensate the offset errors in the axial, radial and angular directions.It has the ability of absorbing and isolating vibration.
5. The elastic coupling has no noise, zero clearance, constant speed, and does not need lubrication.
    The elastic movable pin coupling is a new type of high-performance coupling developed by my country. It combines the advantages of the existing standard elastic couplings with different structures. For example, there are advantages of the plum-shaped elastic coupling: the elastic element is squeezed , Simple structure and high reliability.Overcome the shortcomings of the quincunx-shaped elastic coupling: the half coupling must be moved when replacing the elastic element, and the double-flange quincunx-shapedFlexible couplingAlthough the elastic element can be replaced without moving the half coupling, the structure is complicated, the cost is high, the mass and the moment of inertia are increased, and the application range is limited.When the same torque is transmitted, the radial dimension is much smaller than the GB4323 elastic sleeve pin coupling, with light weight and small moment of inertia.　
The flexible live pin coupling has a wide range of applications, involving various fields of the national economy. In addition to high temperature and high speed special working conditions, shaft transmissions of various mechanical products can be selected. It can be widely used in metallurgy, mining, lifting, and transportation. , Petroleum, chemical, shipbuilding, transportation, textile, light industry, agricultural machinery, printing machinery and pumps, fans, compressors, machine tools and other mechanical equipment and industry shafting drives, will gradually replace the widely used plum-shaped flexible coupling , Elastic sleeve pin coupling, elastic pin coupling, elastic pin gear coupling, core elastic coupling, elastic quick coupling, roller chain coupling and gear coupling Corresponding specifications in standard couplings.
