Step 4 Precision alignment with a Dial Indicator

This video is about My Movie

[@rinnhart]

Hey, I just wanna say, these basic videos, and their commentary, are really valuable in a contemporary era where I fucking forgot half of that millwright class, but suddenly need to explain precision motor alignment to a suit in the morning. Thanks, gents!

[@Mikesfilmss]

I`m glad it helped!

[@kmdiaries6557]

Thank you for this video. Really helpful. This helped me from hours of studying :)

[@funnystories557]

I just wasted 3 hours in class doing my first coupling alignment lol now I'm here thanks for the great video

[@Mikesfilmss]

Thanks! I hope this was a good resource. I have a lot of students that have to do this alignment and its always frustrating for them. It only gets easier with more experience. Just keep trying, you'll get it.

[@carlloggins9297]

First thing you should do is establish length of rod to achieve distance needed to obtain measurements! Then confirm sag of chain jig!of Especially with those

[@electromechanicalstuff2602]

I'm about to do my first alignment. Without any advice from someone who knows how to do it. And it's a 60hp motor. Lol your helping me show up my boss

[@electromechanicalstuff2602]

@@rajeshkumar-ge2tu what do u mean? Edit. I think you mean it's going to shake so bad it'll shake off the rust.... I used to build turbofan airplane engines and pro mod drag racing engines. Dial indicators are not foreign to me. I got the alignment withing 0.004" in all directions. It's been running over a year now and the wind tunnel operator who runs it says it's quite than it's ever been. So thanks for the comment 👍

There are many factors for alignment two shafts, firts, the Rod SAG compensated measurement, them both shafts must be coupling for eliminate any runout condition, don't forget it the soft foot, saludos desde Sinaloa, México.

[@Mikesfilmss]

Those are found in my other videos! thanks for commenting!

[@mccoy1968]

When doing an alignment, you should install the coupling element and turn both shafts together. This factors out any runout or surface deformities in the coupling hub.

[@Mikesfilmss]

Thats an interesting tip. I have to follow the text book and other resources for these videos. If you have a resource that suggests that, I'd love to get my hands on it.

[@keithscott9774]

Exactly. The angular alignment for example is based on an assumption that the flat surface the wiggler is resting on (pump coupling) is flat and perpendicular to the shaft. A way to not have to rotate both shafts would be to first rotate the coupling on the pump side and confirm the flat face is indeed flat, i.e. the wiggler stayed at the same position. Then you know that face is flat and perpendicular to the pump shaft and there's no need to rotate it. However, keep the tip of the wiggler in the same place on the flat surface for both tests.

[@maxymjobin660]

VIBRALIGN will show you that you NEED to tape it or put the coupling first

[@ShaunHensley]

This is correct.

[@boricuaarecibo9259]

I was wondering the same thing I always do it with the coupling installed

[@nivymonyela8180]

Thank you for this video

[@hepburn118]

Great video mate, but it would be helpful if you showed a bit more of the actual moving of the motor. I would have like to see how your dealt with moving the motor over toward you without ruining the angular adjustment while you were at it. I am talking about the 90 a d 270 degrees points here. I always struggled with that, I would get the angular adjustment correct and go to adjust the side to side and ruin my angular adjustment while I was doing that. Very frustrating. G'day from South Australia by the way.

[@Mikesfilmss]

Thanks! I'm glad this helped you. I plan to re do this video with better cameras and more explanation....and better acting haha. Thanks for the comment and the suggestion

[@ahmadparviz2402]

Good information thank you. However the longer side of dial indicator is used to read zero or any other number.

[@justinwalsh6932]

You always set the plunger to half its travel range, so he is calling the 50thou mark on the dial 0

[@trevorlebert1929]

why not use the long needle for your zeroing on the dial indicator

[@barryhill9723]

Great video - You mention book - where can I get a copy?

[@luishernandez5394]

Also where can i purchase that alignment tool you specifically have in your video?

[@anittajoseph497]

very good informection

[@streamfan6825]

Never indicate on a painted surface... get your chain under control ..... theres a reason why that wiggler has a "ball " end... laying it on the side of the coupling isnt getting you a true reading regardless.....you should honestly pull your couplings and work off the shaft in this situation.... as its the shaft you are aligning... the coupling isnt as important as the shaft in this circumstance as its a flex coupling

[@carley3045]

The face of the mating surface of the 2 part hub would have been a much better surface for your angular reading!

[@AlC92575]

[@jameslauinger296]

Both shafts need to turned as one unit (at the same time) and your reading the dial with the Wrong end of the needle!

[@slimmmerman]

You had 50 at 12:00 not 0 but other than that you have me totally confused... thanks for the refresher!You do realize that the long pointy end of the finger is the indicator?

[@shyamcharankumbhakar2184]

[@jloc803dw]

I was thinking the same thing and on the second go around, he was still zeroing to the short end of the dial. But, I still appreciate the video and look forward to finding more of them as I continue down my Mechatronics training at Valencia College, Kissimmee, FL.

[@stephendavis1572]

Great video. Unless these are stainless steel shafts, could you just use a mag base to hold your dial indicator?

I wouldn't because of rigidity. I am not sure of a scenario when a magnet base would be better.

[@carlosmueller1276]

We have been having problems aligning our pumps in the boiler room & recently our manger purchase the same type of indicator but it has two dials , to chain vises, swivel joints, & variety of tubing to mount the indicator. Well, my question is , is it still possible to get proper alignment if I already had the coupling come together or do I need to start back over , & go through each steps as you instructed . Of course the manual tells you to do it one way but being a visual learner , I would prefer to do it your way.

[@Mikesfilmss]

Hello! I think I understand your question and yes you can leave the coupler together. I think if you read a few comments below mccoy 1968 tells me that`s what I should have done for a better alignment. I`ve worked with people who swear by leaving the coupler out and other people that swear by leaving it in. This video is based on the textbook we use and it says to leave it out. I`ve never used your style of alignment tool so I hope this helps! good luck with your alignment!

[@giltupaz5979]

yes,that's rim n face alignment.how about d amt. of shims in near n far foot?you did not show d triangulation computation.

It`s called the Millwrights & mechanics guide 5th edition. by Thomas Bieber Davis & Carl A. Nelson. Its a pretty good all round book and it`s one of the few books that actually has shaft alignment. I think you can pick up a cheap copy off amazon, good luck.

[@Kmn0219]

Is it important to be that accurate? What happens if youre are off by hundreths of a mm?

[@Mikesfilmss]

In short, yes this is very important but that might not answer your question. Below is link to a study on bearing life. about 3/4 of the way down the page is a chart showing that if a shaft is 20mil out it can have 50% decrease in life. This might be an extreme but the article has other levels of misalignment. www.efficientplantmag.com/1999/04/study-shows-shaft-misalignment-reduces-bearing-life/ hope this answers your question.

[@paulpaul4921]

OMG you did the alignment turn it just the motor shaft, that's it's wrong,you need to turn bouth shaft from 0 till 180 and better two have 2 axial dial set up and 1 for radial...And also when you touch the shims it's good to do just in one side (left or right) and make other side like that on horizontally your motor remain in position without not moving..I hope you understand what i say...

[@mechtech2686]

If float of shaft is less then no need to 2 axial dials. It is mostly use when float of shaft is more and normal axial misalignment avoid for flexible coupling spacer .!! also no need to moving both shaft here

I have been a millwright for a number of years and I haven’t used this method in a long time. With the advancements in laser alignment over the last 5 to 10 years why would anyone use this method?

[@Mikesfilmss]

I personally only know of a few places still doing this method but it is on a few pre-employment tests and I believe it is on the NCCER test for millwrights (Don`t quote me on that I`ve never taken the test). I think it also helps student visuals types of alignment but yes most of our curriculum is centered around laser alignment. Hope this helps you!

[@hightekinc723]

Cost of the laser

[@jodyrolandconstruction6577]

Tom Kane the vast majority of companies can afford laser alignment tools. As close to perfect as they do the job companies can’t afford to not have them. Also I’m not knocking this method at all. Just noting that laser alignment is so much better.

when "shimming" your motor whether adding or subtracting NEVER loosen all 4 bolts at same time.. good way to lose your work... do 1 side at a time.. if you dont you will be chasing your alignment alot of times...

The reason they sent 2 dial incisors is to use reverse dial method a reading value of 0 in the horizontal plane is almost never the correct final result you need to alow for themral growth a simple rule of thumb .00083 per inch at 100 degrees of temp rise all the people i have taught Lazer alignment to all benefit from learning rim and face dial indicator first.that is the method you showing on your video
