- Hi, I'm Steve Matthews from ACOEM.
Today we're going to walk through
a precision laser shaft alignment with the ACOEM AT-100,
the newest addition
to our laser shaft alignment product line.
The AT-100 is tablet or app-based
and communicates with the sensors
through a Bluetooth connection.
So the first thing we're going to do is turn on our sensors.
At the same time we open the shaft,
horizontal shaft alignment app on the display unit.
And you can see that the display unit
is searching for the sensors.
And if we touch on the settings icon, we can look
and confirm that my sensors are indeed connected.
See the check boxes are complete
on the sensor serial numbers.
So this generally only has to be done
the first time you use the unit
and after that they connect automatically.
So the first thing we're going to do
is get everything set up correctly.
And in the setup, we have two chain brackets here
and a stationary sensor and a movable sensor.
Generally, the stationary going on the side
that you don't plan on moving
and the move M sensor going on the motor
or the side that you do plan on moving.
And so in the setup,
we have the chain brackets on the shafts
and then we have a laser on each sensor
shooting at the other side.
So this is a dual laser system.
And in that setup, what we need to do is aim the laser.
It is a line laser so it is very easy to aim,
but we do the aiming by moving one sensor
or both sensors up and down on the post.
So now I have each of my laser lines
in the center of each sensor.
The next step, of course, is also going to be
that our sensors need to be square to one another.
And we can double check that
by looking at the angle display on the display unit.
In this case, I have the S sensor at 8.9
and the M sensor at 8.5.
So these should be within about one degree of one another
to start off with.
So now that I have everything set up,
we can go through a precision shaft alignment.
But the first thing I'm going to do is this display
is currently oriented as if you were standing
on my side of the machine for the demonstration.
What I'm going to do for the sake of the camera
is reorient the picture so that the motor
or the movable machine is oriented
for the camera side of the demonstrator.
So this actually comes in handy
during the alignment process also
as you tend to move around the machine
from one side to the other,
the picture can be reoriented to where you stand.
Next step is going to be
to enter the dimensions of the machine.
First thing I need to do is enter from M sensor to S sensor.
In this case we have 180 millimeters.
And then from the M sensor to the center of the coupling,
half of that distance is 90 millimeters.
From M sensor to the front feet of the movable machine,
and this case is zero.
And then from front feet to rear feet, again is 180.
At this stage we select a tolerance
that's generally based off machine speed.
We have four basic tolerances set in the instrument.
But if you want to set your own tolerances,
you can also add a user tolerance.
So today we'll use the 2000 to 3000 RPM tolerance.
So at this point we are set up, have our dimensions,
and can start making our measurements
Measurement icon in the bottom right.
And what we're going to do is call the Verti-Zontal process.
In the Verti-Zontal, what we do
is take a set of measurements.
Requires three measurements.
You can start anywhere and stop anywhere.
And after the measurements are complete,
we're going to do a vertical adjustment
and a horizontal adjustment at the same time.
So measurement icon on the bottom right
looks like a pie chart.
Again, this is our try point measurement method
which means that you can start anywhere
and stop anywhere on the rotation of the shaft.
So there's no requirement to be
at particular clock positions.
To get to the next measurement location,
you simply have to rotate outside the red zone.
There's a red zone and a green zone
drawn around the rotation of the shaft
that you can see on the screen here.
And when the lollipop turns green,
you have rotated far enough to take your next measurement.
We'll take a second measurement.
It's also important that you leave the shaft in place.
In other words, don't rotate it
while it's taking measurements.
So you saw that dancing dial in the center of the screen
that indicates that the AT-100 is taking measurements.
So we just want to leave the shaft in place
while the measurements are being taken.
And then once the measurements are complete,
we have the presentation of data.
And what you have here is the vertical at the top
and the horizontal at the bottom.
Vertical angle and offset.
Horizontal angle and offset.
So the angles are expressed in terms of millimeters per 100
and the offsets are expressed in millimeters.
The adjustments you see here
are some positive, some negative.
And once we get to the next step,
we'll make sense of where this machine needs to go
in the vertical and the horizontal.
So I've got some shims prepped to make this adjustment here.
We hit the shim icon.
Select the shim icon.
And, it draws us a picture of exactly how much shim to add
or remove from the front feet and the rear feet.
You do the same thing to both rear feet
and the same thing to both front feet.
So in this case, I need to add 0.9 in the back
and add 0.5 in the front.
So like I said, I've got some shims
prepared here for this adjustment
and make my rear adjustment first
and then my front adjustment.
Okay, now once again, we call this Verti-Zontal
so we won't be tightening these motor bolts
or movable bolts down because we will be making
a horizontal adjustment at the same time.
Again, the green icon indicates the horizontal.
So we move to the horizontal to make that adjustment.
And the screen shows us how much to move
and it even scales the arrows
based on how bad the misalignment is.
So I'm going to actually move the the rear one first
because it seems to be the worst
and make sure my bolts are backed off there.
And I have 0.37, 0.35.
So I'm going the correct direction.
Went a little bit too far.
And you can see now that the color code
is starting to change from red to orange and green.
We want to get both the angle and the offset in the green.
And you can see we're now within tolerance
and we'll tighten up those bolts
and take a remeasure before we document the final results.
So again, I'm coming back to the position I started in
to repeat the process in the same way
I did the last measurement.
Take my first set of data.
Again, it doesn't have to be in exactly the same spot,
but if you repeat the process the same way
from one measurement to another,
your data results will tend to be more consistent.
Second measurement.
And finally a third measurement.
(silence)
So now you can see we have all green angles offsets
in the vertical and the horizontal
and a green check mark on both vertical and horizontal.
So now we will save this data
into a combined report of this shaft alignment result
plus a Softfoot measurement that we took earlier.
And that is done.
Here we're going to save the alignment.
So there's two steps to this.
We're going to save the alignment.
I'm going to call this AT-100.
(silence)
All right, so that saves our alignment.
And then we're going to produce our final report
by combining the shaft alignment with.
If we had saved data from a soft foot adjustment beforehand,
we can do that as well.
So in generating the PDF report,
there's several lines available for naming,
putting a plant name in, a username in,
a machine name, and any machine notes that you may have.
And so we'll select the AT-100 and Softfoot.
And then save it.
And then this creates the PDF report
which is a combination of those two reports put into one.
And now we have that file saved
for future reference on this device.
So that completes the shaft alignment process
with the ACOEM AT-100.
