COUPLING MISALIGNMENT

In general, the misalignment capacity of CD Floating Shaft Couplings is related to the speed at which they operate and the mass of the floating shaft, which is governed by its diameter and length. This table shows the recommended maximum allowable angular misalignment:
Speed
DBSE (Distance "C")
Up to 30"
30" - 60"
Over 60"
To 500 RPM 3° 2.5° 2°
500 - 1000 RPM 2.5° 2° 1.5°
1000 - 1500 RPM 2° 1.5° 1°
Above 1500 RPM 1° .75° .50°


By reducing the allowable misalignment (and therefore stresses in the discs) at higher operating speeds and longer DBSEs, the disc pack can better support and stabilize the floating shaft, which will result in longer coupling life, smoother operation, and less vibration to the connected equipment.

DYNAMIC BALANCING

The close tolerances used to manufacture CD Couplings in conjunction with the composite disc pack, make CD Floating Shaft Couplings especially well suited to high speed and long span applications. Occasionally, the application may require Dynamic Balancing of the floating shaft coupling.

This graph illustrates general application guidelines.
