Coupling Information:

Type of Coupling
The two shafts connected by the coupling, due to manufacturing and installation errors, deformation after loading, and the influence of temperature changes, will cause changes in the relative positions of the two shafts, which often cannot guarantee strict alignment. According to whether the coupling has elastic elements, whether it has the ability to compensate for various relative displacements, that is, whether the coupling function can be maintained under the condition of relative displacement and the purpose of the coupling, the coupling can be divided into rigid couplings. Flexible couplings and safety couplings. The main types of couplings, their characteristics and their role in the role of the transmission system Remarks
Rigid couplings can only transmit motion and torque, and have no other functions including flange couplings, sleeve couplings, jacket couplings, etc.
Flexible Couplings Flexible couplings without elastic elements can not only transmit motion and torque, but also have different degrees of axial, radial and angular compensation performance, including gear couplings, universal couplings , chain coupling, slider coupling, etc.
The flexible coupling with elastic elements can transmit motion and torque; it has different degrees of axial, radial, and angular compensation performance; it also has different degrees of vibration reduction and buffering, improving the working performance of the transmission system includes: Various non-metallic elastic element flexible couplings and metal elastic element flexible couplings, various elastic couplings have different structures and differences, and their functions in the transmission system are also different.
Safety couplings transmit motion and torque, overload safety protection. Flexible safety coupling also has different degrees of compensation performance, including pin type, friction type, magnetic powder type, centrifugal type, hydraulic type and other safety couplings
