Defining Angularity in Shaft Alignment

Nov 27, 2012· Since the coupling faces and the shaft centerlines are perpendicular, exactly 90 degrees, the slope change across the coupling faces is the same as the slope change along the lengths of the shaft centerlin In other words, if the coupling faces have a slope of 2 mil per inch, the shafts also have a slope of 2 mil per inch...

Shaft Alignment

The total indicator reading gives the actual difference in distance between the coupling fac Because of the dial position relative to the face of the coupling, bar sag will not have an effect on face readings It will still be an issue to consider when taking rim readings though Figure 40 shows a typical setup for taking the face readings...
