Involute Gears Explained 

This video(-series) is unique. I have not seen anything so clear and still in-depth ever!

Thanks! It's a work-in-progress... imgur.com/a/ng18Bgj I actually didn't know about the 'sliding factor'. Or at least not with this name. Could you give me a source on that?

@@gergelybencsik8626 Contact ratio would be the correct name. Profile shifts affect working pressure angle which modifies the final contact ratio of gear pairs. Can’t wait for the next video!

Couldn't agree more

Absolutely!

Manimazing! 🥳🥸

I'm planning to follow up with undercutting and profile shift. I can't promise angled gears, I need to research them first, and going 3D is a bit of a challenge

@@gergelybencsik8626 yeah its quite a task. keep doing what you like and are good at. I like this presentation style and plan on watching whatever you upload.

Wouldn't angled gear just me cross section of a cone instead of cylinder? Circle to cylinder makes 3d, cylinder to cone makes angled. Just a guess.

@@sirme1798 It probably is exactly this, but I want to see how it behaves with slightly misaligned axles and also how the geometry of helical gears applies to angled couplings (most car differentials)

I am planning to follow up with undercutting and profile shift of involtue gears. After that, I might do one on cycloid gears. If you mean other types like bevel gears or worm gears... I would need to switch to 3D animation for them, and I kinda wanted to stay 2D

yeeeeeess11 🤣

Thanks :)

Well, this sliding topic seems to be a recurring thing that I now must make into part 2 - if I ever finish it. Can you give me a source for your rolling claim? This is where I stand: there is rolling only at the middle part of the flank, at the pitch point, and the closer you get to the root or tip of the gear, there's more sliding. And since the rolling is only momentary, and not sustained over the contact surface, the motion must be categorized as 'sliding'.

@@gergelybencsik8626 In engineering school I definitely was taught of the tooth's rolling motion. When checking resources with google, it appears that the rolling motion is appended with "sliding" motion at the extremes of the tooth engagement. I suspect that much of this type of engagement depends on the accuracy of the tooth form.

I had the opportunity to speak with a gearing specialist who is recognized internationally. He confirmed with what I found and reported on 2 days ago: Rolling motion when teeth are in contact at the pitch circle, and sliding motion as the contact point moves away from the pitch circle. Glad to be able to update my dated knowledge!
