Hey your videos have very good quality. I want to see more videos about machine elements(shaft, belt, chain, bearing). It would help engineering students and others who interested in these.
I loved it! Just subscribed, and it has already proved invaluable to my new design, prototype and fabrication service. We just incorporated a couple of weeks ago; I'm using Solidworks to design prototype parts, which we print up on our Formlabs SLA 3d printer. All the passion and creativity will get us nowhere without fundamentals, and you have so generously and succinctly provided tools for our foundation! Shukriya, CDR Krotchety USN
learn engineering i like your videos too much ............your video is just fantastic i have almost all your video ........you are doing appreciable work please keep on continue.............please make more video and make world knowledgeable.............may god help you...............from India.
Sorry for all the racist comments. The speech is clear and easy to understand for me, and I especailly liked the parts about calculating the allowable parameters using the Lewis formula.
Is the diameter of the two gears at 1:45 the diameter of the root circle, pitch circle, or tip circle? I assume pitch circle since they intersect at a single point but it is unclear in the video because if it is the pitch circle then Dp1 + Dp2 does not equal allowable width. To find the allowable width, you would also have to add the addendum of each gear (assuming the diameters are of the pitch circle). If you don't do this, the teeth will stick out slightly further than predicted with the equation, therefore improperly calculating the space that the gears will take up.
thank you kind sir for your efforts, I really appreciate your work :D peace and many blessings be with you my friend : ) p.s. my wife loves your accent !
This video was very nice. I have a question though @ 3:47. Can I ask what Dp will be used to solve the module? was it dp1 or dp2? Anyone please help. Thank you so much!
if using "diametral pitch" automatically means that u are design this gear in "inch" unit right ? Or else u will use "module" if u are working in "milimeter" .... i have some doubt bout it...
Oh man, I've made plenty of gears, but those equations just came at me from nowhere and meant nothing to me 🤣 Was hoping you'd give us something on how to calculate the shape of the teeth.
Hello, thanks for the great video. Can you please tell me how to find the value of stress in the Agma strength equation and also the values of the other factors, so that we can insert the values in the equation and find the value of 'b'. Thanks again.
I have a pinion with OD = 40 mm and no. of teeth = 13, pitch of rack is 7.9 mm. I want to manufacture similar rack and pinion but i need pinion and rack details for manufacturing. I did some calculations and all my values are matching with the above rack and pinion except number of teeth = 14 but number of teeth are 13 . Why is my number of teeth not matching with the actual value?
The critical value of the stress is dependent on the material you use and this has to be greater than the stress generated as calculated from Lewis Bending Equation
so it means that whatever torque is generated by the output gear, the same torque is transmitted by the shaft on which the output gear is mounted......
The thinking is that the pinion should be a little harder because it has more revolutions and therefore should be a little stronger. The harder tooth will also wear on the softer tooth and you then want that wear on the gear.
Books like shigley, bhandari write the procedure in a very shit way this one is very appropriate and useful and the basic steps can be applied also for helical and worm gear.
Keep people with relevant videos, watch how to do calculations on Gear Drive : ua-cam.com/users/results?search_query=how+to+do+calculations+on+gear+drive
Hey, Miguel Grande And Luisa Uchitel, and everybody else... You can read what speaker is trying to say in English at... www.learnengineering.org/2013/02/spur-gear-design.html
You can find out derive radii of gears by considering speed ratio and space constrains. If gear 1 is lifting the mass, Torque required , T1 = R1xMxg
sir could you plese send this ppt

I always knew engineering was technical, but I never thought something that looks so very simple had such a paramount science behind it...

Your video taught me in minutes what was covered in 4 months in my university
very well presented and coverage of surface stress and load stress very good coverage. Thank you!!

watch again "DESIGN FOR SURFACE RESISTANCE" check its spelling in presentation........

your videos are all wonderfully put together. may the ONE bless your knowledge and bring the learned people to your channel.
Very clear, to me anyway, and I'm as English as they come (as you can see from my childhood photo on the Norfolk Broads!). Great video
Thank You for your Tutorial. It Helps me studying AutoCad.

after shown this lecture especially know about spur gears thanks
Great, I really appreciate your effort
And that's why mechanical engineers are so awesome
Thank you very much.I really appreciate your work.please do post more such type of videos.
Thanks sir great apreciable work
awesome video.That's very simplest gear video,thanks for share in this video.
I found your video very helpful and entertaining, thank you very much sir and keep up the good work.
You are soo damn underrated bro... Thank you soo much

What about fatigue? Wouldn't it be necessary to take into account?
Also, congratulations for the well put video.
So apparently we have to assume t1 and then check it with the interference equation. Whats the best way t1 without just throwing out a random number?
i dont think there is any, its up to your desired design constraints
I have to admit it was a really usefull, and well-structured video.
But i had to stop for a minute to spam 1:03 for a bit :D
i have a big doubt on undercut dimension. can you please explain
very interesting and informative

Watch this video. Very useful
Absolutely true , I will support u guys
Idk what you guys are talking about. That's a pure all-american accent right there!
Great information, thanks for sharing this!
can you upload a video regarding the design of worm gears?? ASAP
Very good explanation
thank you
in the case of chain and sprocket mechanism should we consider these parameters?
This is so interesting and so well put together but I had great trouble in understanding your English Sir
+David Wootton Indian English . The accent is thick and not even for me, and I am Indian
This video is surely gonna help me complete my project. But could you please tell me how did you get that equation for interference at 3:25.
01:02 when you try to start a diesel engine on cold weather 😂
addandam and dandam
Did you make bearing design video? 😢 i really need it
Can you add subtitles to your videos to make it easier for people to understand because I had a hard time understanding what you said
Same to me, I keep replaying the video after seconds so that i can understand sometimes he mixes Hindi and ENG

Hi
What is the centre formulation for joint 2 gears... Or 3
can u upload videos for rack and pinion
calculation
In the lewis bending equation ,why the bending stress is not depending on the material we use?
The critical value of the stress is dependent on the material you use and this has to be greater than the stress generated as calculated from Lewis Bending Equation
@@aswinrajeevan3674 you know that u replied to a question that was asked 2 years ago before u replied.

Angular velocities of two meshing gears cannot be different. But they can have different linear velocities
Vice versa
I'm sorry but what do you say thy represents at 3:40mins?
***** Phi is the pressure angle of the gear.
Which is the software ur using
so it means that whatever torque is generated by the output gear, the same torque is transmitted by the shaft on which the output gear is mounted......
what is the formula to calculate the SAP?
good plz.... keep it up
can you explain the creep-fatigue interaction?
I´m sorry, as a non native speaker, it is very hard to understand what you are saying.
Don't be troubled my friend. I am a native speaker and it doesn't help.

Sir can you tell me " why in design of gear pair, difference in brinell hardness number of pinion and gear is kept 30
The thinking is that the pinion should be a little harder because it has more revolutions and therefore should be a little stronger. The harder tooth will also wear on the softer tooth and you then want that wear on the gear.
