NM coupling guidance for mixer and agitator drives with changing process loads.
Mixer and agitator torque can change with viscosity, fill level and whether the machine starts under load. Include process duty together with the motor or gearbox data.
What to include in the application RFQ
| Punkt | Hva som skal bekreftes |
|---|---|
| Process duty | Material, viscosity range and loaded/unloaded start condition. |
| Drive | Motor or gearbox speed and power. |
| Shaft interfaces | Both shaft diameters, keyways and restricted mounting length. |
| Cycle | Starts, stops, reversals and batch frequency. |
Where an NM coupling fits
NM couplings suit many general mixer drives where a compact resilient connection is appropriate. Higher shock, severe cyclic duty or unusual environment may call for a different coupling construction.
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.
