How does the coupling work?
Coupling function
It is used to connect two shafts together. When the machine is running, the two shafts cannot be separated. Only after the machine is stopped and the connection is removed can the two shafts be separated.
Type of coupling
Due to manufacturing and installation errors, deformation after loading, and the impact of temperature changes, the two shafts connected by the coupling can cause changes in the relative position of the two shafts, and often cannot ensure strict alignment.
Couplings can be divided into rigid couplings, flexible couplings, and safety couplings based on whether they have elastic components, whether they have the ability to compensate for various relative displacements, whether they can maintain the coupling function under relative displacement conditions, and the purpose of the coupling.
Rigid coupling
Rigid couplings can only transmit motion and torque, and do not have other functions, including flange couplings, sleeve couplings, and sandwich couplings.
Flexible coupling
Flexible couplings without elastic elements can not only transmit motion and torque, but also have varying degrees of axial, radial, and angular compensation performance, including gear couplings, universal couplings, chain couplings, slider couplings, and so on
Flexible couplings with elastic elements that can transmit motion and torque; With varying degrees of axial, radial, and angular compensation performance; It also has varying degrees of vibration reduction and cushioning effects to improve the working performance of the transmission system, including various non-metallic elastic element flexible couplings and metal elastic element flexible couplings. Various elastic couplings have different structures and significant differences, and their roles in the transmission system are also different.
Safety coupling
Transmit motion and torque, overload safety protection.
Flexible safety couplings also have varying degrees of compensation performance, including pin type, friction type, magnetic particle type, centrifugal type, hydraulic type, and other safety couplings.
