In a fit such as H7/h6, what would happen if the hole comes in MMC (smallest) and the Shaft/Pin comes in at MMC (biggest) as well. Is there an unspoken rule in the workshop such as a Shaft/Pin should never be made at MMC. Always remove another...0.002 - 0.003? And what are the possibilities that a Hole will come in at MMC (at lower limit).
Zero line means no deviation from the basic size. Right now size increases at upward direction but if you take at bottom of shaft as basic size and zero line then size will increase in downward direction. And fundamental deviation curves will exchange position and so on..... Please watch the video again. You will get it. Thank you
thanks sir, It was really very helpful for me i was always getting confused between shaft and hole basis system . sir can u please explain the TAYLORS PRINCIPLE . in your nxt video THNX
as in case of interference fit diameter of shaft always greater than diameter of hole , we need to increase diameter of hole by indirect heating (to avoid changes in material property of the hole, for example heating a bearing in oil bath) enough to enter the shaft and locate on defined position. or in some cases we use liquid nitrogen to shrink shaft diameter so that it will enter the hole and locate at its position.
by expanding (increasing) the hole diameter using indirect heating methods mostly and if interference is less then just applying force. nole: on shft end there will be chamfer to ensure location in the hole.
By applying pressure with huge amount of applied force to shaft by forcefully forcing into hole so as to make sure that shaft holds tight with hole and minimise vibration while working
Can who clear up for me these following question? please! -Based on which basis we choose the appropriate tolerance? In addition to basics such as: +Tolerance system of the hole, shaft + Assembly type:( clearance, transition, interference) -I have the assembly between the hole with the shaft, the nominal diameter 20. But there are three cases happened: Case 1: Both hole and shaft are plastic. Case 2: Both hole and shaft are metal. Case 3: One of the two parts is metal and another is plastic. So, what difference in the above three cases when we choose the tolerance for them?
1st of all it depends on Purpose of assembly Magnitude of load Type of load (radial, axial etc.....) Then size of job. In the questions you asked when material of construction is plastic it is clear that load is minimum. So it will depend on type of load & purpose of assembly.
Thanks so much for answered my questions, about the second question sorry but I don't still understand so much. Do you have any document explant how to choose the correct tolerance of the assembly has the different material? Thanks again!
Never understood this concept in my engineering studies. Thankyou
Awesome video sir
All topic concept clear
There is no confusion 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
if that didn't clear my concept nothing else can. thank you very much for the video.
Thank u bayya...I understood well...😍😍😍...
That's a great work.. I have been searching for this for a very long time.. Now it's clear.. Thank you.
Enjoyed the video in a nice understandable way . Thank you dear brother for this.
best video till now on shaft and hole base system.
So much technical content in such a short video.............Thanks a lot....keep the good work
Really a good description ! no one has used images in this much good way !
Wow!! What a clear explanation 👍👍👍
I just got it in one video after many confusing videos...
Great explanation.
Thank you
very good description. we can understand simply and all confusions will be finished
Good video. Well explained and appropriate visual aids
Such a nice video ....i hv clearly understand my doubt in between transition and interference fit ....thank u so much...
Thank you so much for sharing...... A easiest n a clear explanation
wow that explanation was awesome.....thank you so much for taking efforts for animation!
Fantastic man....very clear. Pls go head with other topics and also other subjects...
Super explanation good explanation
Best video and explanation on youtube
Barun Pratap thank you
Thank you 💘 from srilanka
U r knowledge ful great sir
easy to understand... well explained.. clear
Thank you soo much....best video and explanation
Thank you sir, you actually cleared basic doubt.
this video is fully understandable....
very special you did it . fantastic.
Mayankraj Prajapat thank you

Thank you sir ✌️ you are saviour 😎
Perfect 👌👌👌👌👌 explanation sir
Was very useful.thankyou.,
Thanks a lot sir!
Pls make more videos on other topics of Mechanical Engineering too.
bruh you are the best!
GREAT EXPLANATION THANKS!
very good video. my all confusion has gone away
Nyc video bhai
Thank you
This one was really informative
Sahi hain. Seedhe baat no bakwas.
Very good explanation
thankyou sir great work.
Thanka a lot bro 👌👌👌
Helpful ✌️
its really useful... thnx😊
fit interpretation video uploaded check it. may be useful for you and thanks for your comment.

Hello
finally i know what those diagrams meant.... couldn't find it in other videos
How do you fix the zero line? Why should the zero line not be there at the bottom of the shaft?
Zero line means no deviation from the basic size. Right now size increases at upward direction but if you take at bottom of shaft as basic size and zero line then size will increase in downward direction. And fundamental deviation curves will exchange position and so on.....
Please watch the video again.
You will get it.
Thank you
Superb
beautiful sir...
Good one👍
anil kumar thank you
god bless you sir, thank you very very much
Nice explanation.sir , can you please upload a video like this on design of limit gauges
Finally the mystery solved
Just awesome
Glory to God 😍😍😍
useful video...Thank You
fit interpretation video uploaded check it. may be useful for you and thanks for your comment.
thanks ...it helped a lot
thanks sir,
It was really very helpful for me i was always getting confused between shaft and hole basis system .
sir can u please explain the TAYLORS PRINCIPLE . in your nxt video THNX
thank you sir
this is sooo helpful!
good video !
Rakesh Potluri thank you
one question , how can we fit shaft in hole in interference fit?
as in case of interference fit diameter of shaft always greater than diameter of hole ,
we need to increase diameter of hole by indirect heating (to avoid changes in material property of the hole, for example heating a bearing in oil bath) enough to enter the shaft and locate on defined position.
or in some cases we use liquid nitrogen to shrink shaft diameter so that it will enter the hole and locate at its position.
by expanding (increasing) the hole diameter using indirect heating methods mostly and if interference is less then just applying force.
nole:
on shft end there will be chamfer to ensure location in the hole.
By applying pressure with huge amount of applied force to shaft by forcefully forcing into hole so as to make sure that shaft holds tight with hole and minimise vibration while working
i want a video on go gauge or no go gauge concept with full visualization........ please help
Great
Thanks , nice video , 4
superb
Thanks it is good video
thanks sir....it helped!
Super teaching sir
Thank you
nice video

very clear
Nice sir
It's good
This video is awesome but its not getting attention.
nice
thank you. so much
thanks
I'm observing..
sir iss topic pe eek hindi ma bhi video banaya na. english ma clear se samaj nahi ata ha.
Sir l'm do't understand zero line
aap engineering sikhane lage to kabila engineer banaana tay hai
Anna tamil language video anupunga
sir gr information hindi me mile to aor accha rahega
thank you sir
I like it tight
Dylan T yea me too bruh
