What should be considered when choosing a coupling type?

When choosing a coupling, you should consider the working environment, service life, lubrication and sealing, and economic conditions, and then refer to the characteristics of each coupling to choose a suitable coupling type. The relative displacement of the two shaft axes caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.

The size and nature of the transmission torque required by the coupling, the requirements for buffering and vibration reduction functions, and whether resonance may occur. For large couplings, they should be able to be assembled and disassembled without the need for axial movement of the shaft. The selected external dimensions and installation methods, in order to facilitate assembly, adjustment and maintenance of the required operating space.

Both sides of the sleeve are in the form of elastic chucks, and the middle part of the coupling is an integral sleeve with a damping groove. The vibration damping groove is used to absorb vibration, increase the alignment of the two shafts, reduce the assembly errors caused by the axial, radial and angular displacements of the two shafts, and make the transmission movement accurate. The two sides of the coupling are 2 tightening rings, the shaft is loaded into the chuck, and after tightening the screws, the frictional force transmits torque through the interaction between the elastic ring and the shaft through the interference fit and extrusion.
