Alignment of sliding bearing couplings
Thread Content
This post was last edited by Zui o Hongchen on 2017-3-28 at 15:54. When adjusting the alignment of couplings, how is alignment done for couplings on equipment supported by sliding bearings? What are the differences from aligning couplings with rolling bearings? Are there any relevant documents or materials available? Thank you! When adjusting alignment, disconnect the coupling – what is the difference between the results obtained with and without disconnection, and which method is simpler and more accurate?
There isn’t a big difference. It involves cold state, hot state alignment. Generally, a centering curve is provided.
When aligning the couplings, separate the two couplings for adjustment – is the resulting alignment accurate?
Centering is about the axis. It’s not a coupling.
But generally, the axis alignment is achieved through a coupling; then why would one need to disconnect the coupling?
Alignment has nothing to do with the coupling. The coupling has machining errors. Precise alignment is required; the coupling cannot be used as a reference. Disconnecting the coupling facilitates alignment.
When adjusting the disengagement of the coupling, do the rotors on both sides rotate at the same time and at the same angle? If not, how to ensure coaxiality!
