- So now we're gonna go in and perform
the shaft alignment function using our RT-300.
Now, we're gonna make this assumption.
I pulled the guard off here
and this was grossly misaligned,
like you'll often find maybe the cufflinks shoot up.
You're gonna have to replace it.
I've already performed some rough in steps just
to get it a little closer.
Doesn't matter for the laser,
the laser will more than adequately measure,
you know half inch of misalignment,
10 millimeters off,
it wouldn't make any difference.
But I want to rough it in
to minimize forces in the couplings.
So I'm not deflecting the shafts in it.
So now let's go ahead and mount our laser on here,
we're gonna do an alignment check.
So I'll turn on my M-Sensor,
(machine clacking)
mount it to the machine,
and again we're just simulating this
because this is just a little small motorized demonstrator,
but the process it would be exactly the same,
if it was a thousand horsepower machine.
I mount my S-Sensor,
(machine clacking)
just kind of getting roughly in
the same angular position on each one It isn't critical now,
we'll actually let the laser tell us
what our relative angles are on each sensor,
I'll get them snug,
I'm gonna go into the shaft alignment app,
and we'll let it start up,
that it paired to the sensors.
So we paired up to the sensors,
got our beams flashing
and tell my relative angular positions of each sensor.
I'm gonna give these adjusting knobs about a half turn,
just to make sure that they don't accidentally slip during
the alignment process,
so now I'm going to touch on the measure application here
and wants to know how far
the heads are apart from each other,
from the center of M-Sensor rods
to the center of the S-Sensor rods,
are three and a half inches.
So I'll put that value in,
wants to know how far it is from
the M-Sensor to center of coupling,
that isn't quite as critical a measurement,
but I need to try to get it close as I can
and I will call it one and a half inches.
Third dimension is from the M-Sensor
to the center of the inboard feet,
where the shims would go,
and that is two inches.
And lastly distance from the center of the in-board foot to
the center of the outboard foot,
and on this machine,
that is six and three quarter inches.
Last thing I need to tell it is the running speed.
We're just gonna make an assumption,
this is a 3,600 machine,
so we will align to that value,
and now we're ready to take our measurements.
Now, typically I always like to rotate
in the direction of rotation
or rotate my shafts for the measurement,
you don't really have to,
it's just a habit of mine.
So I'm gonna roll all over one side,
check my angles and they are within a half a degree or so,
so they're pretty close,
so I will tell it to measure,
it's gonna show me the image,
giving me some guidance on where to go with it,
and I'm gonna take the first measurement.
I'm gonna take just a moment and now I need to rotate it
at least 30 degrees and one way or the other,
in this case I'm gonna rotate it up straight up to vertical.
I have a little backlash in my coupling,
so I have to control that.
I'm just gonna put this sensor in the lead
and that'll clear that and get these very close
to being the same,
I'll take my second measurement,
and lastly I'm gonna rotate over here somewhere
in the horizontal position,
and I will take the third measurement.
And obviously we do have an alignment problem.
We're gonna save this because you always want documentation,
and we will name this machine fan one as found.
And now that I've saved the data,
is I wanna go to the shim icon,
and it tells me I need to add 21,000,
it's under the two inboard feet,
77,000 it's under the two outboard feet.
So let's do that.
(clacking)
So now I've added in the shims
that I need to correct it vertically,
I wanna go into live mode now
and I'm gonna correct it horizontally.
Now I'm gonna use my magnetic base for my dial indicator
as a steady wrist.
I'm simply going to adjust it,
so it will hold my sensors in a horizontal position,
so I can make the horizontal move hands off.
This way I don't have to hold the machine up try
to hold them still at once.
I'll go by the guidance,
so my RT-300 and it tells me that I need
to move the machine that direction,
so I'll start using jacking bolts,
being careful not to overshoot it
'cause I don't wanna make extra work for myself.
I just wanna get it where it needs to be.
And again, we're not shooting for zeros,
we just wanna get our alignment intolerance.
So that looks pretty good,
and now we will start finger tightened
and bolt number one,
two, three, and four.
(machine clacking)
And now I'm gonna go back to one and snug it just a little,
I don't wanna be too powerful with this,
because you can accidentally move the motor around a bit.
So we're just being very cautious
about how we tighten this up.
The smaller it is,
the more critical that is.
So now I'm gonna tighten one,
go to two,
I'll go to three,
and then lastly I'll go to four.
Now if we did our part,
we should have a pretty good alignment here.
So let's remeasure and see.
So now I'm gonna hit remeasure key,
and tell it I wanna take one more measurement,
I'm in a pretty good place right here using this steady rest
or this dial mag base is a steady wrist,
so I'll go into the measurement icon
and it tells me to rotate over to there.
I've done that already
so we'll take our first measurement.
I'm gonna rotate up to at least 30 degrees somewhere out
of that position.
We'll take our second measurement,
and we'll take one more rotation
to get our third measurement,
and now we have a good alignment.
So it's a really quick process,
onscreen guidance,
we just follow the instructions on the RT,
use a little common sense with this
and we've done a quick alignment job.
Now, do we wanna save this?
Obviously we do, because I wanna show a before and after,
so I just go back into the save icon
and I'm gonna name this machine final.
And so now I'll have both the before and after saved,
and I've got documentation showing
that I have a line in the machine.
So now that we've aligned it,
what do you think we're gonna do?
We're gonna do another vibration test on it,
and see if we've improved the vibration levels on it.
