Very good video! One mistake - it said that the gears slide smoothly. The gears do not slide! All of the contact between the gears is ROLLING contact! That's the reason for using the involute shape!

Great video, very informative. Incredibly unpleasant and distracting background muzak. Thanks

Very cool. You made HackADay.

Thank you so much for making these animations and giving these explanations!!!

Awesome man, thanks a lot, 4h of lectures in 6 min is crazy

“Hold on a second, lemme get this backlash out.” -nobody

crazy video

which are the parametryc ecuations?

The videos are great work - it took me whole weeks to find out the same things myself. I was willing to design some transmission mechanism using rolling instead of sliding - no luck so far, but perhaps it's possible using some intermediating bodies. Rolling friction instead of rolling cause a lot more energy loss. It would be great if somebody would make an episode or even better an app/algorithm that You type gear parameters and it outputs parameters on charts marking at what point other charts get them maximal values. So for an instance You type meshing wheels diameters and it shows You the most optimal closest gear sizes for given parameter we want. Do we want maximum performance (the least energy loss), do we want maximum strength ? Do we want maximum angular precision ? - I would advice helical (twisted) gears in that case. Do we need more strength ? (thicker gear with more contact area or bigger tooth). Do we need the least backlash (no clearance). I think that there could be a separate episode about the clearance itself - how do we cut the clearance ? equal gap from the gear edge, or, we cut the clearance with some angles - how to position them ? are 2 smaller gears meshing (causing contact) at once better than 1 bigger ? What's the optimal tooth width ? I forgot the context and wasn't digging into it too much, but at some point You said that some module proportion is standardised certain way and You don't know why, but that's the way it is - I bet that it's got something to do with being able to mesh with different diameter gears at once. Personally I found out that as many as short tooth's You've got as most energy efficient it goes as it becomes more like just rolling 2 pipes on each other, but it can withstand less load so You can widen the gears (increasing the mass and overall contact surface, but distributing the pressure on bigger surface. The question is at what width the gear is to wide ? If the gear needs to rotate at constant speed as heavy it is as good as more inertia, gives less angular accelerations - least backlash, but in case you need the gear to transfer accelerations you want it to be as light as possible to do not delay power transfer. After months of thinking about gears and bearings for my innovative engine project I designed a bit improved gears that should waste significantly less energy, last longer, stay cooler (less thermal expansion) and run smoother (with the least angular accelerations - in theory good designed gear is not having a backlash, but in practice all of them does, even the helical ones), but I'm still asking myself all the questions looking for potentially better solutions than using gears...

1 min of clear explanation

Brilliant video!

This is amazing work. Very well presented.

fantastic explanation!

Damn dude this animation is amazing. I made a similar one a few years ago but this is so much better.

Excellent explanation! Thanks so much for this!

excellent! thank yoi

please, i download the code and tried to open it in pythonanywhere but it doesn't open because some problems in the code can you please help me with that problem

i was stuck at involute circles for a good 2hrs. this video resolved my confusion in 5mins

you are a beast i love you

Thank you. That was quite helpful and you explained clearly. also the animations are astonishing👌👌

May you provide a video designing gears into Autodesk inventor or solidworks?

Awsome

The explanations and animations are simply wonderful - thank you so much for taking the time to compose this series.

everthink is cool but the music in the background is very disturbing

You've taken a potentially difficult concept and explanation and delivered it beautifully - the animations are superb also - thank you

Отличное представление!

Beautiful explanation thank you so much!

That’s a great animation

The video about involute gear was great, please make more like it👌

cant believe this is free. Thank you so much

Excellent video. Why is it so hard to find good explanation of the reason behind gear shapes?

The best explanation I have seen by far.

Very good video! Thank you.

Clearest video i watched see.

Thank you so much for this great video!

Absolutely amazing video! You took something that was hard for me to understand from other places and broke it down into a 1 minute video, and now I can start to understand more complex explanations of aliasing. Thank you!

Was going to suggest Kalman but then i saw it at the bottom of the ocean. I think Filters that are easy to implement are the best in most scenarios

the music is too loud it makes it hard to focus on your voice

Terrific explanation. Would love a series where you go over other filters like you mentioned with the iceberg.

Awesome video! thanks

Brilliant. New subscriber question: What's the average percentage difference in slip-free rotations vs. real-life rotations with slip for an average situation, say Honda accord driven gently vs spiritedly (lots of acceleration) at something like 120 km/h on average? Is it "a couple percent" or more like 0.1 or less%

Nice! Regarding your last argument: It can be shown mathematically that there has to be sliding, or rotation will not be smooth.

Kuch samaj nahi aa raha hai

I was so concentrated and that face in the end made me giggle😄 thanks, great explanation

Saviour ....

hahaha nice bro easy and straight to the point

Bro amazin explanation I loved this mini serie, thank you so much for you work!

Very well explained! As noted in the description, the main source is tec-science with their latest recording of th-cam.com/video/lMmWsbdTDng/w-d-xo.html. But I would say this version is shorter with the same amount of information involved. Thanks!

Lose the 'music'.

Amazing video!! This helped so much!!!
