Selection of coupling type When selecting a coupling type, the following items should be considered.
①The size and nature of the torque to be transmitted, the requirements for buffering and damping functions, and the possibility of resonance.
②The degree of relative displacement of the axes of the two shafts caused by manufacturing and assembly errors, shaft loading and thermal expansion deformation, and relative movement between components.
③Allowable dimensions and installation methods are the operating space necessary for ease of assembly, adjustment and maintenance. For large couplings, it should be possible to disassemble and assemble without the need for axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing and economy should also be considered, and then refer to the characteristics of various couplings to select a suitable coupling type.
