Inspect and clean the drive and driven shafts of any burrs, rust, deposits or sharp edges.
Check the dimensions of the shafts and the keys.
Mount the hubs on the respective shafts. Carefully adjust both hubs until there is a 3/16", metal to metal, gap between each hub and the center ring.
Rough align and tighten the foundation bolts on the drive equipment.
Re-adjust the hubs on the shafts such that the gap on each side of the ring is 0.1875" ± 0.020".
Tighten the set screws on the hubs. Use any removable strength thread locking compound such as Loctite® 242.
Align the drive and driven shafts to the specifications provided by the equipment manufacturer. Laser alignment is recommended to get the best coupling performance. If no specifications are available then the following values may be used for general purpose machines like centrifugal pumps and motors
Speed
(RPM) |
Parallel
Misalignment |
Angular Misalignment
(Per 10" Dia. of Coupling) |
| 600 |
within 0.005" to 0.009" |
within 0.010" to 0.015" |
| 900 |
within 0.003" to 0.006" |
within 0.007 to 0.010" |
| 1200 |
within 0.0025" to 0.004" |
within 0.005" to 0.008" |
| 1800 |
within 0.002" to 0.003" |
within 0.003" to 0.005" |
| 3600 |
within 0.001" to 0.0015" |
within 0.002" to 0.003" |
| 7200 |
within 0.0005" to 0.001" |
within 0.001" to 0.002" |
Check the coupling setting dimensions once again to ensure that the gap between each hub and ring is within 0.1875" +-0.020".
Put the Coupling guard in place.
Start and check for any unusual sound or vibration.
Take vibration readings and record the same for future reference.
