- So now we're gonna go into the alignment process.
We've run into vibration diagnosis on this machine
and we know we have a misalignment problem.
So I already matted my sensors up on a machine.
In this case, since this thing is so small,
and this is a nice little trick to use in industry too.
I'm gonna use my magnetic brace
or my dial indicator mag base as a stop.
So I'm gonna use that on one side
and we are gonna go into the shaft alignment app,
and we're gonna put in our dimensions
and we'll take a quick measurement on this
and see if we're out of alignment.
So we'll give it just a second to pair up.
We will adjust down our sensors as we need to,
to make sure that they are seeing each other
at about the same angle.
Go down here to the measurement.
And it wants to know the distance between the laser heads
from the stationary to the movable.
And that is 88 millimeters.
The second dimension is from the center of the M sensor
to the center of the coupling.
And we're pretty close to 46 millimeters.
Distance from the center of the M sensor
to the center of the in-board foot,
where the shims would go.
And that is 55 millimeters.
And lastly, the distance from the center
of the inboard foot to the center of the outboard foot.
And I will use my tape measure
and we can see that that is 170 millimeters.
Now we have to choose the running speed.
And remember, this runs about 3,600.
So we'll go 3 to 4,000 RPM
so we can set our tolerance level.
And now we're ready take our measurements.
So I'm gonna rotate this over to one side.
I'll let my little mag base hold this still.
I will check my angles to see that they are pretty close
and touch on the measurement icon.
It's gonna give me some guidance on what I need to do.
So I've rolled over to there,
and now I'll take the measurement.
Now I need to rotate at least 30 degrees
in one way or the other. So I'm gonna rotate this up
toward 12 o'clock, toward vertical.
Take my second measurement.
And lastly, I'm going to roll back over here
somewhere on the other side of the machine
and take my third measurement.
So obviously we're out of alignment.
We have three that are out of tolerance.
One kind of close,
but we're gonna have to shim this to fix it.
So let's go ahead and do that.
But before I do, I wanna save this data.
This is really important
that you've saved the before and the after,
just to prove that what you did made the machine better.
And I'm gonna name this machine "before".
Now that it's saved into our tablet on the RT300,
we can go right into the shimming process.
So it's telling me I need a .45 millimeters
on the inboard both sides,
and 1.7 millimeters on the outboard.
So let's go ahead and do that.
So now I've put in my shims that the RT300's called for
to make my vertical correction.
I'm simply gonna roll my sensors over to horizontal,
go into the live mode.
And it's going to show me
which direction I need to go and how far,
and I'm just gonna follow the arrows for guidance.
And I'm going to use my jacking bolts
to start positioning the motor.
Taking my time, going to the biggest arrow
to making a correction.
In this case it's on the outboard.
And I just want to sneak up on it
and bring this machine into alignment horizontally.
And that's pretty close.
So now we've made our horizontal corrections.
I'm gonna hand tighten my bolts down,
one to two to three to four,
and I have these numbered and I suggest you do as well.
Just follow a numbering sequence each time.
It really doesn't matter which one is which,
as long as you establish your tightening sequence
and tighten the same way each time.
And I usually wanna watch the screen
to make sure I'm not overaggressive in my tightening,
'cause if you tighten too much at once,
you'll tend to move the motor
just a little bit side to side.
In our case, we don't wanna do that.
On this it really isn't a big deal,
but if this is a 3,000 pound motor,
I don't wanna be pushing it around any more than I have to.
So just take your time on tightening.
We got it just snug,
so it looks like we're still in tolerance.
So now let's take our final measurement,
hopefully it's final,
and see if we've corrected our misalignment problems.
So I've rotated over to the nine o'clock position.
I'm gonna take the first measurement.
I'm gonna rotate up somewhere near the 12 o'clock position.
Make sure that the lasers are sitting still.
I'll take the second measurement.
And I'm going to rotate back over
toward the nine o'clock position.
And I'll take my third measurement.
And if we did our job correctly
we should have a well aligned machine, and we do.
So now we wanna document this.
You always wanna be save the before and after.
So we're gonna save this and we're gonna call it "final".
So now we've saved our before alignment
and our after alignment.
And we think that was the majority
of what we had going on that was wrong with this machine.
So the next logical step would be to remove our lasers,
power the machine back on
and let's take another vibration measurement
and see if we corrected our problem.
