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
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!
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
if that didn't clear my concept nothing else can. thank you very much for the video.
Thank u bayya...I understood well...😍😍😍...
Awesome video sir
All topic concept clear
There is no confusion 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Never understood this concept in my engineering studies. Thankyou
best video till now on shaft and hole base system.
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.
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 !
very good description. we can understand simply and all confusions will be finished
Wow!! What a clear explanation 👍👍👍
I just got it in one video after many confusing videos...
Great explanation.
Thank you
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
Super explanation good explanation
wow that explanation was awesome.....thank you so much for taking efforts for animation!
Thank you 💘 from srilanka
Best video and explanation on youtube
Barun Pratap thank you
U r knowledge ful great sir
Fantastic man....very clear. Pls go head with other topics and also other subjects...
easy to understand... well explained.. clear
Sahi hain. Seedhe baat no bakwas.
bruh you are the best!
Nice explanation.sir , can you please upload a video like this on design of limit gauges
Nyc video bhai
Thank you
this video is fully understandable....
Superb
Thank you soo much....best video and explanation
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
Very good explanation
Helpful ✌️
Thank you sir, you actually cleared basic doubt.
Thanks a lot sir!
Pls make more videos on other topics of Mechanical Engineering too.
very special you did it . fantastic.
Mayankraj Prajapat thank you
finally i know what those diagrams meant.... couldn't find it in other videos
Was very useful.thankyou.,
Finally the mystery solved
Perfect 👌👌👌👌👌 explanation sir
beautiful sir...
Thank you sir ✌️ you are saviour 😎
GREAT EXPLANATION THANKS!
Good one👍
anil kumar 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
Thanka a lot bro 👌👌👌
This one was really informative
its really useful... thnx😊

i want a video on go gauge or no go gauge concept with full visualization........ please help
This video is awesome but its not getting attention.
thank you sir
Just awesome
Glory to God 😍😍😍
thankyou sir great work.
Thanks , nice video , 4
good video !

thanks ...it helped a lot
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
Thanks it is good video
