Requirements of Good Shaft Alignment / Good Coupling Setup
- it should be easy to connect or disconnect the coupling.
- it does allow some misalignment between the two adjacent shaft rotation axes.
- it is the goal to minimise the remaining misalignment in running operation to maximise power transmission and to maximise machine runtime (coupling and bearing and sealings lifetime).
- it should have no projecting parts.
- it is recommended to use manufacturer's alignment target values to set up the machine train to a defined non-zero alignment, due to the fact that later when the machine is at operation temperature the alignment condition is perfect

Famous quotes containing the words shaft and/or coupling:
“The subterranean miner that works in us all, how can one tell whither leads his shaft by the ever shifting, muffled sound of his pick?”
—Herman Melville (1819–1891)
“The time of the seasons and the constellations
The time of milking and the time of harvest
The time of the coupling of man and woman
And that of beasts. Feet rising and falling.
Eating and drinking. Dung and death.”
—T.S. (Thomas Stearns)
