CouplingThe main technical requirement of assembly is to ensure the coaxiality of the two axes. Excessive coaxiality error will cause additional load on the coupling, drive shaft and its bearings, which will cause vibration of the machine, premature wear of the bearings, Failure of mechanical seals, and even fatigue fracture accidents.
The deviation of the coupling during assembly:
1. The two halves of the coupling are parallel and centered.
2. The two halves of the coupling are parallel, but not concentric.
3. Although the two halves of the coupling are concentric, they are not parallel.
4. The two halves of the coupling are neither concentric nor parallel.
The coupling is correct in the first situation and does not need to be adjusted.The last three are incorrect and all need to be adjusted.
