CouplingThe function and principle of

1.CouplingFEATURES

Used to connect two shafts together. The two shafts cannot be separated when the machine is running. The two shafts can be separated only after the machine is stopped and disconnected.

2.Couplingtype

The two shafts connected by the coupling, due to manufacturing and installation errors, post-bearing deformation and temperature changes, will cause changes in the relative positions of the two shafts, and often cannot be strictly aligned.According to the elastic unit of the coupling, the ability to compensate various relative displacements, that is, whether the connection function can be maintained under the relative displacement and the use conditions of the coupling, the coupling is divided into rigid coupling, flexible coupling and coupling.

rigidityCoupling: It can only transmit motion and torque, and does not have other functions, including flange couplings, sleeve couplings, clamping shell couplings, etc.

Flexible coupling: a flexible coupling without elastic elements, it can not only transmit motion and torque, but also has different degrees of axial, radial and angular compensation performance, including gear couplings, universal couplings , Chain coupling, slider coupling, etc.

The flexible coupling of elastic elements can transmit motion and torque; it has different degrees of axial, radial and angular compensation performance; it has different degrees of damping and cushioning, which improves the working performance of the transmission system, including the flexible coupling of non-metal elastic elements Flexible coupling with metal elastic elements.The structure of various elastic couplings is different, and their roles in the transmission system are also different.

Coupling: Transmission of movement and torque, overload protection.Flexible couplings also have different compensation properties, including pin type, friction type, magnetic powder type, centrifugal type, hydraulic type and so on.
