Luftkompressorer
NM coupling selection points for compressor drives with cyclic loading and vibration.
Compressor drives can see cyclic torque and vibration, so shaft size alone is not enough. Include the compressor type and operating pattern when requesting an NM coupling.
What to include in the application RFQ
| Punkt | Hva som skal bekreftes |
|---|---|
| Compressor type | Screw, reciprocating or other compressor and the drive arrangement. |
| Speed & power | Normal operating speed and motor/driver power. |
| Load pattern | Starts, unload/reload cycles and repeated shock if present. |
| Justering | Installation alignment condition and any recurring vibration issue. |
Where an NM coupling fits
NM couplings can provide a compact flexible shaft connection for suitable compressor duties. If repeated element damage has occurred, include that history so the drive condition can be reviewed rather than simply replacing the element.
Replacement and installation notes
For replacement work, include the existing coupling marking, photos and measurable hub dimensions. For new installations, provide the shaft drawing or actual shaft dimensions. Align the connected equipment to the machine manufacturer’s requirements before operation.
Request an NM Coupling Quote
Send the NM size if known, both shaft diameters, operating speed, driven equipment and quantity. Add a drawing or photos for replacement work.
