Carrier 17EX specifications Measuring Angular Misalignment Elevation

2.Parallel in elevation Ð This alignment is also made with shims, but it cannot be made while there is angular mis- alignment in elevation.

3.Angular in plan Ð This position can easily be lost if placed ahead of the two adjustments in elevation.

4.Parallel in plan Ð This adjustment cannot be made while there is still angular misalignment in plan and can easily be lost if elevation adjustments are made.

Correcting Angular Misalignment

Preparation Ð Shaft angular misalignment is measured on the face of the coupling hubs or on brackets attached to each shaft (see Fig. 38 and 39). Brackets are preferred since they extend the diameter of the face readings.

Attach a dial indicator to one coupling hub or shaft and place the indicator button against the face of the opposite hub. Position the indicator so that the plunger is at approxi- mately mid-position when the dial is set to zero. Both shafts should be held tightly against their thrust bearings when the dial is set and when readings are taken.

To be sure that the indicator linkage is tight and the button is on securely, rotate the coupling exactly 360 degrees. The dial reading should return to zero. Accept only repeatable readings.

Measurement Ð Occasionally, coupling faces may not be per- fectly true or may have been damaged in handling. To com- pensate for any such runout, determine the actual or ``net'' shaft misalignment as follows:

Check the opening at the top and at the bottom of the cou- pling faces (or at each side when making plan adjustment). Rotate both shafts exactly 180 degrees and recheck the open- ings. Record the difference. (Example below is in inches.)
