- Hi, I'm Steve Matthews with ACOEM.
Today, we're gonna walk through the process
of doing a precision shaft alignment
with the AT-200 laser shaft alignment system from ACOEM.
The first thing we'll talk about is the initial setup.
The initial setup,
you can see I've already got my chain brackets
mounted on the shafts.
There are also optional magnetic brackets for this device.
The first thing to do is to turn the sensors on.
This will prepare the sensors for Bluetooth communication
with the display unit or the tablet,
and if we go into
the horizontal shaft alignment app on our tablet,
the settings icon will show us
that indeed my two sensors are communicating
via Bluetooth with the device,
so at this point, I can also just hit the check mark,
but in this case, we'll be conducting this video in metric,
so here, I also have the opportunity
to change from inch to metric,
and that's part of the settings menu here,
so once I have my settings
all clear for the alignment,
I can see there are green lights and values
for the S and the M sensor,
so I know everything's connected properly.
Next is final setup of the sensors on the shaft,
and in the AT-200,
along with all
of our laser shaft alignment systems at ACOEM,
it is a dual-laser system,
so there's a sensor on the M sensor.
We have a movable and a stationary.
Movable is generally an electric motor,
so that's the machine we plan on moving,
and there's an M sensor and a S sensor.
Each one has a sensor.
Each one has a laser,
and so the setup is as simple as
if you look at this range,
which is 30 millimeters, 30 millimeters of sensor surface,
there's a little triangle mark in the middle,
so we basically wanna get our lasers
roughly in the middle of the sensing surface,
and that's very easy to do
at any distance,
so we clip our sensor
onto the posts,
and then, finally, we wanna make sure
that our sensors are square to one another
to start off with,
and so that is done by,
generally, you can get there visually
if you just look at the,
if you look at the sensors and the posts,
you can kind of see how square they are to one another,
and then, you can double-check over here on the screen.
I have my M sensor at 9.9 degrees
and my S sensor at 9.8 degrees,
so we just wanna get these
within about 1 to 1 1/2 degrees of one another.
Now, to get started,
we'll put in the dimensions of the machine,
and the first dimension to put in
is from M sensor to S sensor.
In this case,
we have 180 millimeters.
Hit the check mark when you have that dimension in,
and then, the second dimension
is from the center of the coupling to the M sensor.
In this case, we have 90 millimeters.
M sensor to the front feet of the movable machine.
In this case, we have 0 there,
and then, front feet to rear feet on the movable element.
Again, we have 180 millimeters.
Next, we'll be selecting a tolerance.
Tolerance is based on machine speed.
We have four tolerances available in our chart
that's built into the AT-200,
but you can also put user-selected tolerances in
that can be saved for future alignments,
so once we have the tolerance set,
we can begin taking measurements.
Now, the measurement icon is in the bottom right,
and in this device, our GuideU process
is one that highlights in yellow
what the next step in the process is,
so this is our measurement.
Now, before I start,
we'll explain briefly the different measurement techniques
that are available in an AT-200.
Today, we're gonna do this alignment in express mode.
Express is a way of measuring
in which the measurements are taken automatically
at each measurement location,
and is very useful if you're working alone.
We also have tripoint,
so tripoint is this one at the top
that looks like a pie chart.
Tripoint is simply just like express mode,
however, the user must touch the measurement icon
for each measurement,
so there's an actual engagement on the screen.
There's also the traditional clock mode
with inclinometer values and without inclinometer values,
and there are some applications
where each of those is useful,
so today, again,
we'll be doing this alignment in express mode,
so what that means is that when I drop below 9:00
and then turn back up above 9:00,
it will automatically begin sampling measurements,
and you can see that
as the icon dances on the screen,
and so once it's complete taking a measurement,
then I can rotate to the next measurement,
so it's important not to rotate while it's measuring,
but all we we have to do is rotate outside of the red zone,
so you can see that's not,
you know, a full rotation.
We can start anywhere and stop anywhere for measurements.
However, for our final measurement,
what we'll do is stop at the 3:00 position,
and this will put us in the correct position
to be able to look at our horizontal data live
when we do the vertizontal adjustment,
and we'll get to that in just one moment,
so as you can see,
we have an alignment
in which this is a fairly unique result,
but we have vertical values that are in the red,
so the values are outside the tolerance range,
and horizontal
that are in the green.
However, we gotta get all four in the green
for the tolerances to be good.
Now, before I move on here,
I want to show the orientation of the picture,
so currently, this picture
has the motor on the right-hand side,
which is oriented
for a person standing on my side of this machine.
We'll make this a little bit more useful for the camera
by flipping that picture around
and orienting the motor
to be on the left-hand side
according to the orientation of the camera,
which is on the opposite side of the machine for me,
so you can walk around the machine
and reorient this as many times as you want,
so once again, we've got the vertical values
and the horizontal values,
and then, we'll walk into, touch the shim icon,
and go straight into our vertizontal alignment process.
Vertizontal is a word that we made up at ACOEM years ago
to describe doing an alignment in one step
where we make a vertical adjustment
and a horizontal adjustment at the same time,
so the first of those
is going to be the vertical adjustment,
and you can see here
that this graphic
makes sense of plus and minus numbers,
so instead of trying to figure out
does plus mean take away shims or minus mean add shims?
This graphic will show you with the arrows going in
that it means to add shim,
and if we were taking shims out,
it would have the arrows going the opposite direction,
so in this case, I need to make some adjustments
in the amount of
0.9 millimeters on the rear feet,
and I have some shims here already prepared,
and I put that 0.9 in both rear feet,
and I'll put the 0.5 in both front feet,
and now, the chances are,
once I move to the horizontal position,
I will no longer have green there,
and I'll probably have to make some adjustments
after making the shim change,
so here I go from the vertical to the horizontal
with the horizontal icon,
and once you touch that,
it brings up the horizontal data, which is now live
because I've positioned the sensors
at the 3:00 position.
It can also be positioned at the 9:00 position either side,
but I wanna have the sensors
on this plane that I plan on moving,
so you can see the arrows are scaled
for how much adjustment I need to make,
and again, I can tell which direction to move.
I'm looking at it upside down,
but I'm sure it's very clear on the camera side of this
that I need to go that way,
and as I do so, the numbers get lower,
and the actual icon of the machine
starts to adjust with your movement,
and make sure I'm loosened up so I can move here,
and so now I am,
whoop, I just went just a little bit too far there,
and you can see the icons
are starting to change the angle on the offset
from red to green or orange.
Orange means that you're within
twice what the tolerance is,
and, of course,
green means that you're within the tolerance,
so the objective here is not necessarily to get to 0,
but just to get to green,
so once we get within that tolerance,
we will tighten the machine up.
You can see this warning icon comes up
that tells me whether or not
my sensors are still square to one another.
It's a bit of an indicator
to tell me if I have a lot of looseness
that's affecting the measurement in the coupling,
so we will remeasure at this point,
and then, in the final step,
in the final step, we will document this alignment.
Once again, it's important to leave the shaft stationary
while the measurement is being taken.
Okay, so now that I have my,
all my measurements are complete,
I have green and I'm within tolerance.
There are just a couple more things to cover here,
and that is before we get to the reporting,
we'll show you some other settings
that are available in the AT-200.
Number one is we can change the color of the motor,
make the graphics a little bit more realistic.
We can also change the type of machine that we are aligning,
so that the picture sort of corresponds
to the type of machine that we have.
In this case, I've selected a pump,
so when I create this report,
it's gonna have a red motor and a pump on it,
and then, finally,
we did this alignment with standard tolerances,
which are angle and offset at the coupling.
There are additional features available in the AT-200
where you can select a spacer shaft tolerance type
or a coupling gap tolerance type
in that where you put in the angularity
in terms of so many millimeters
per diameter of coupling,
so just a couple different ways
that you can enter tolerances
depending on how you want these presented
in the data and in the reporting,
so now that we have that completed,
we will save this alignment,
and I'll flip this around here so I can read it,
and I'm gonna call this alignment
AT200.
Okay, and there's a quick snapshot of the data being saved,
so now, I'm gonna create a report,
so I'm saving the alignment data
but then creating a report
in which I can label the plant name,
the machine name, the username,
and there's another field for additional notes,
and then, I'm gonna select
which data I want presented in this report,
so in this case, I want my AT200 data.
Just before I started,
I took a picture of my demonstration unit here,
so I'm gonna put that picture in the report,
and then I'm also going to put,
I believe I have a softfoot measurement
that I can also put in the report,
so then I create the PDF report.
Excuse me. Pressed the wrong icon.
I create the PDF report
and give it a name,
and then, I'll show you here
what that's gonna look like.
All right, now we've got that report created.
It's a PDF.
I've got softfoot measurements, picture of the machine,
and my final alignment results,
so that is the complete alignment process
with the ACOEM AT-200.
