We have already discussed “Basics of shaft alignment” and “Shaft
alignment terminology” in our previous post. We have also studied in our
previous post about the need and advantage of successful shaft alignment for
maintaining the healthiness of our equipment. As we have already discussed the
various terms and terminology used in shaft alignment and also we have
discussed the activities those are very important to follow before the final
shaft alignment
.
I will request to all my colleague, friends and readers to read “Basics of shaft alignment”, “Shaft alignment terminology” and "shaft alignment procedure" before reading this article to complete understanding of precision shaft alignment in step by step.

Shaft alignment plays a very crucial role to secure
a healthy maintenance system, so let us start the main subject now without
wasting your valuable time.
We were discussing the shaft alignment in our
previous discussion “shaft alignment procedure”. Now we need to follow the below activities to
secure the final shaft alignment.
Fixing of coupling with driver and driven shaft
Now we need to install the coupling (we are
considering here the gear coupling) with driver shaft and driven shaft, before
installation of gear coupling we need to check the coupling bore size and shaft
size and there must be tolerance as per specified by the manufacturer.
There must not be any axial or radial play between coupling hub and shaft and driver and driven shaft should rotate freely with coupling hub fixed on the respective shaft. After successful installation of gear coupling on shaft, we need to position the driver and driven unit over the respective base plate.

Preliminary inspection of angular measurement
After positioning the pump and motor over base
plate, we will measure the angular measurement between both coupling hubs with
the help of feeler gauge. During inspection of angular clearance between both
coupling hubs, we need to check angular clearance at four locations i.e. first
at 00, second at 900, third at 1800 and fourth
at 2700. We need to adjust the angular clearance below 0.05 mm total
indicated runout at all four above locations.
Preliminary inspection of parallel measurement
Once we have adjusted the angular clearance with specified
dial testing indicator reading i.e. 0.05 mm, we need to measure the parallel
alignment of both coupling hubs with the help of straight gauge. First we will
measure the parallel offset in horizontal axis and after that we will measure
the parallel offset in vertical axis.
We must note it down, during preliminary alignment, we will have to recheck the alignment if we are doing any changing whenever we change the position of equipment to secure the parallel/angular alignment. Suppose if you are doing any changing for parallel alignment, you need to recheck for angular alignment and vice-versa because any changing in position of equipment may change the alignment.

Piping and duct work
Once we have completed the preliminary alignment, we
will have to fix the piping and duct work with the pump and we will check for
any stress during connection of piping and duct work with the pump. We will
remove if there is any stress whether stress is in horizontal or vertical
position.
Dial indicator application to determine the total indicated runout
Once we have completed all the piping and we have
also secured the angular alignment as well as parallel alignment with 0.05
total indicated runout. We will check the shaft alignment with the help of dial
indicator. We will align the shaft with a target of 0.02 mm total indicated
runout.
We will use rim and face indicator method of to
secure the final alignment of shaft. We will also discuss Rim and face method of
shaft alignment very soon.
Fabulous post admin, it was too good and helpful. Waiting for more updates.
