When choosing the coupling type, consider:
1) The size and nature of the torque to be transmitted, the requirements for buffering and damping functions, and whether resonance may occur.
2) The degree of relative displacement of the axis of the two shafts caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3) Permissible dimensions and installation methods, the operating space necessary for ease of assembly, adjustment and maintenance.For large couplings, it should be able to be assembled and disassembled without the need for axial movement of the shaft.
In addition, the working environment, service life, lubrication and sealing and economy should also be considered, and then refer to the characteristics of various couplings to select a suitable coupling type.
For standardized and serialized couplings, after selecting the appropriate type, the model and structure size of the coupling can be determined according to the torque, shaft diameter, and speed.In most cases, the applicable shaft diameter of each type of coupling has a range. The maximum and minimum shaft diameters are given in the standard, or the size series of applicable diameters are given. The two shafts to be connected should be in this Within range.Generally, the diameters of the two shafts to be connected are different, and the shapes of the two shaft ends may also be different.
