Amazing!!! The way you visualized a profile shift at 2:45 on the two involutes based on center distance is phenomenal!! You should make a video expanding on the profile shift coefficient and it’s effects on sliding factor and undercut!

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!

I once worked as a shipping clerk at a machine shop that made precision gears that were used to check production gears. Although it was not strictly necessary for my job, I became fascinated with the geometry of gear teeth, otherwise known as involutometry. That was 40+ years ago, but I still find it interesting!

One thing that you didn’t point out, though it’s clear from your animation, is that the force applied to the gear at the point of contact is always perpendicular to the radius of the gear. This means that as the gears rotate they are always producing the maximum torque on each other and it is constant as they spin.

Excellent video presentation. I understand that for gears to mesh properly they have to have the same module, (M1, M2, M3, etc) and I think that is the modern version of the older imperial Diametral Pitch system. For those not familiar with it, could you do a presentation of Diametral Pitch. I know that basically it's the number of teeth per inch of circle circumference. Thanks for making the video and for taking the time to upload.

@BasementEngineer Жыл бұрын

Very well done, thank you! A couple of points, though. Lose the music! It is not necessary. Secondly, you state that the gear teeth flanks slide on each other. In fact on spur gears they ROLL on each other. Certain other gears, such as worm gear and worm, and hypoid gears, see sliding motion and for that reason require a special lubricant. Good animation, and the formulae for the involute curve are the first time I have seen them.

@gergelybencsik8626 Жыл бұрын

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'.

@BasementEngineer Жыл бұрын

@@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.

@BasementEngineer Жыл бұрын

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!
