Checklista f\u00f6r installation och fels\u00f6kning av NM-koppling<\/h1>\n

Correct installation starts before the flexible element is fitted. Clean the shafts and bores, check for burrs, confirm the hub machining, and verify that the driver and driven equipment are mechanically ready for alignment.<\/p>\n

Mount The Hubs<\/h2>\n

Install each hub to the approved shaft position. Confirm key engagement and fastening. Do not force a hub onto a shaft that does not meet the intended fit.<\/p>\n

Align The Shafts<\/h2>\n

Use the equipment alignment procedure to control angular and parallel offset. A flexible coupling can accommodate limited movement, but it should not be used to hide a poor base, bent shaft or bearing problem.<\/p>\n

Fit The Flexible Element<\/h2>\n

Install the element cleanly and without cutting or pinching it. Bring the hubs to the approved spacing and verify free rotation by hand where the equipment procedure permits.<\/p>\n

Commission And Inspect<\/h2>\n

After start-up, check for abnormal noise, temperature rise, visible dust or fragments, hub movement and repeated element damage. If wear returns quickly, investigate load, alignment and environment before replacing the element again.<\/p>\n
