Selection
Selection of Coupling Type When selecting a coupling type, the following items should be considered.
① The size and nature of the required transmission torque, the requirements for buffering and vibration reduction functions, and whether resonance may occur.
② 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.
③ The allowable dimensions and installation methods, and the necessary operating space for easy assembly, adjustment and maintenance. For large couplings, it should be possible to disassemble and assemble under the condition that the shaft does not need to move axially.
In addition, the working environment, service life and conditions such as lubrication, sealing and economy should also be considered, and then a suitable type of coupling should be selected with reference to the characteristics of various types of couplings.
