Bevel Gears vs. Crossed Helical Gears

Crossed Helical Gears Vs. Bevel Gears
•••
I talked about crossed helical gears (also known as screw gears) in my last video, and I wanted to highlight the difference between these and another type of perpendicular meshing gear- the bevel gear. Bevel gears are much better in high torque/high speed application, but the restriction is that the shafts must intersect at a point. Crossed helical gears have shafts that don’t intersect which give a ton of design freedom. The cost is that they aren’t as efficient and also only really work at lower speeds and lower torque applications.

Good on you for flipping the comments in the section into more cool content. All of history is made up of many people concurrently finding things out. You’d spend your whole life just researching to make sure you know everything out there. Keep up the cool work!

[Algardraug]

I think it was very clear that you created a proof of concept for your own application of the gears in the last video.

[Warthog]

I printed the gears yesterday and I can definitely see the amount of friction on it

[court]

Usually only the spider gears are straight cut bevel gears. The ring gear and input will be hypoid gears.

Actually you will find them in a "Torsen-differential" in a car, where the friction is key for the torque transfer mechanism.

Thank you! I was legitimately getting mad at the comments on the last video of people claiming you are trying to "claim" inventing the cross helical gears. All I saw was you providing a proof of concept for 3D printed gears.

car differentials are actually often use beveled helix gears. It's so the drive line can enter the diff from above the wheel axles. So its actually using both techniques in one!

[poorboys]

I appreciate but more so respect you making this video clarifying the bit about not inventing it. I was one of the (I assume) many who made a smart-ass comment about that in the last one. So well done, sir! And (as if you care), in my opinion, this deserves an atta boy and a hardy pat on the ass!

[trancetechkid]

Wow. A well explained, well thought out video with a host who can speak properly on a subject he is well educated on. This is the most refreshing thing I’ve seen on YT in a long time.

I love this. There’s a lot of content online hyping up unique mechanisms like they’re better than the more common stuff, but although they’re interesting and cool a lot of this technology is niche for a reason and the more common and mundane things are often more successful because they’re actually better. Simplicity is the backbone of good engineering, stronger, cheaper, better.

A Torsen limited-slip diff uses helical gears 🙂 But doesn't transfer all the torque through them in that way.

[JustRollin]

YouTube is lacking a lot of good mechanical engineering content. I'm glad to see this video.

[abbetkahjit]

Love your videos man, as an engineer I love seeing all sorts of new mechanical apparatus’s

[jamesmancini]

I love seeing a young person who is actually interested in learning about engineering. God bless him.

You got a new subscriber just because of how you responded to all the smart comments on your last video, your channel is great and I liked it but this was cherry on top that you took time to explain yourself and educate people like me that don’t know much about this

[KnownPhoenix]

This is actually pretty cool and I love that you mentioned what your job is. I've been working more and more on my car but I'm pretty illiterate so finding out more about what you do might give me the path I need. Thank you for providing that first step, I hope to be as educated as you! Keep going, I'm joining this road with you

[StateGenesys]

Amazing that you actually explained why the gears are better, and their actual weak points. 20/10 video, needs to be trending tbh

[HCivicFg]

Great video addressing comments. Wonderfully done.

[photondebuger]

Helical gears are in transmissions too they are mostly just like parallel in their axis right but is used because they are more quiet than straight cut gears. Really cool stuff
