It is true that helical gears can handle more speed than spur gears and are used in almost all car transmissions. Nevertheless many racing transmissions and most motorcycle transmissions are using spur gears.
Correct, racing cars/motorsports use spur gears in their transmission due to their higher efficiency. In addition, spur gears don't generate any thrust (axial loads); thus, the overall transmission design can be lighter which is critical in a motorsport configuration (To handle the axial loads, helical gears necessitate the use of heavy-duty transmission casings, shafts, and bearings). Still, the incredibly high noise the spur gears generates makes them less desirable for being used in the transmission of regular cars (except the rear gear in older cars that used to be a spur gear).
@@CAEPlus Why don't automotive transmissions simply use herringbone gears to null the axial thrust, rather than transmitting it to the bearings? Is there an advantage to using helical gears with axial bearings, instead of using herringbone gears and radial-only bearings?
@Carl Hansen Herringbone gears are substantially more expensive to manufacture, and can be tricky to assemble.
@@stevenrs11 Thank you for answering and that makes perfect sense. So it is a matter of tradeoffs, that axial bearings are a more economical choice to herringbone gears, in terms of which one is easier to construct.
Are there any performance tradeoffs between the options of herringbone gears with radial-only bearings vs helical gears with axial bearings? Such as does one of these have better friction or efficiency characteristics?
@@CAEPlus yeah the noise is bit annoying ruclips.net/video/dmJH84FnQa8/видео.html
Indeed it's a great slide, waiting for lessons
Thank you! Glad you found it useful. We are planning to roll out some lessons in the near future. Please stay tuned for more details.

Excellent teaching skill.
Many thanks!
Thank you.
You're welcome!
The part where you are talking about a high point gear. I can't help but link that to machining on a lathe. Most people think having the tool at center of the part is ideal. It isn't. And being under the centerline would cause the part to climb over the tool. Which I assume would have almost the same effect with this style of gear. I only mention this because in turning on a lathe, you want the tool slightly above center.... "for better wear resistance" on the tool. (And a more consistent cut) Seems a bit coincidental, doesn't it? Almost like one learned off the back of another manufacturing style. 😅
This video is powerful video
Glad you found it useful!
May i know what's the name of your background music? so calming, nice explanation btw
Well-Done
Thank you!
The best video a bout Gears i ever seen ...
Thank you for your kind comments!
Great Videso for Gears! mark
Glad you liked it. Thanks for watching!
Something I didn’t see mentioned is how to choose the number of teeth to use in each gear when their ratios are low (but not 1:1) or the number of gears to use for high ratios. In particular, would it make sense to use numbers that are relatively prime in order to evenly distribute the wear between pairs of meshing teeth? What are the pros and cons of using a few large teeth versus lots of small teeth?
this is a material question, so the best way is to think about this in a extreme way. if I make really really small thin teeth like we are talking tin foil thin then rather then turning the gear it will fail because the foil thick teeth bend and break. so that's why you don't want too thin. so rather then starting with 2 gears lets start with 1 gear. so their are 360 degrees in a circle let's pretend each gear is 1 degree you have a stick that's on a line that enables you to push only one gear at a time. you push the 360 teeth gear and move the gear exactly 1 degree you push it 360 times and you have made 1 rotation let's say you lifted a 1 pound weight 1 inch in doing so. now let's say we have a gear that has 30 degree gear teeth meaning their are 12 of them on the circle, you push it with your stick on a line and you move the circle 30 degrees you push the gear 12 times and you make 1 full rotation and lift the 1 pound weight 1 inch. the weight and the distance stayed the same so it takes less torque to do it 360 times vrs 12 times. the lever, pully and gear are all the same they are taking doing something a lot and trading for using greater effort the lever moves a greater distance, the pully uses more rope, the gear turns the circle a smaller amount all basically the same thing.
thanks
You're welcome!
It makes sense for helical to produce axial thrust. But when using two gears that have opposite angles shouldn't they cancel each other?
Thanks for your question! Correct, the axial thrust force can be canceled by using a double helical gear (herringbone). Even though there is a net zero axial force on the shaft with a double helical gear, the axial loads should not be ignored. These forces create a moment that must be counteracted by the bearings and must be included when calculating bearing loads during the gear engineering design process. This is one of the main reasons why helical gears have a lower efficiency than spur gears. I hope we were able to answer your question!
This was a good one
Glad you enjoyed it!
Am I the only one that hates the music? And why do I think that it is totally unnecessary?
We got few comments about the background music and will adjust it in our following videos. Thanks for your comment, though!
And for us old farts the background noise makes it very difficult the hear
@@andrewwolf4430 We will get this fixed in our following videos. Thanks for your comment!
You might want to watch and listen to your video before you send it out.
@Boyd Pennington Of course, we check our videos before posting them on RUclips as we take the effort to create them 😉 (which, by the way, takes a very long time). The background music level sounded okay to us, but after receiving the feedback, we will reduce it in our upcoming video.
I was just chillin but now after completing half of it I have a pen and a paper in my hand lol
We are thrilled to hear that our video has sparked your interest to the point of taking notes! 😊
Nice video....
Thanks for the visit!
I really enjoyed the video, but the music was a bit too loud. Otherwise, best gear video I've seen so far
Glad you liked it. Noted about the music! Thanks for your kind comment!
If you ever do a more indepth video on gears, you should also address harmonics, as that is a crucial design feature for gearboxes most people overlook.
Very good point! We are planning to cover more complex gear mechanisms (Planetary gear, strain wave gear, etc.) used in transmissions/gearboxes in a separate video. Thank for your comment!
Very nice
Thank you!
Wonderful video, good work! Too bad you had to put music in it.
Happy you liked the video! Next time we will adjust the music level. Thanks for your comment, though.
I can't believe you have less subscriber than 1 million. It was a great video useful for everyone not just for mechanical engineering students.
Thanks for your kind words! Really glad you liked it.
@@CAEPlus Maybe if you eliminate the background music?
If you had a spherical ball would it allow better turns? Like a Dyson ball?
Correct, a gear similar to the spherical ball in Dyson vacuum cleaners can offer improved maneuverability and ease of turning. For instance, unlike traditional gears that primarily rotate along one axis, a spherical ball gear will be capable of moving in any direction. This omnidirectional functionality allows for sharper, more fluid turns in the mechanical linkages connected to the gears, thereby improving overall operational efficiency.
Recently, Japanese engineers and scientists have conducted significant research on spherical (ball-shaped) gear designs. This innovative work is currently still in the research and development phase, reflecting ongoing advancements in the field of mechanical engineering.
Please let us know if you would be interested for a video on this subject.
Thanks for your comment!
Solid video. Nice background music.
Glad you liked it! Thanks for your nice comment :-).
Yes the music is a distraction??
does the worm gear and the wheel gear attached to it move in the same direction? And also, if we were to have a straight bevel gear with two gears horizontally on it would they both move in the same direction?
Thanks for your question, and sorry for our late response.
Actually, the axes of rotation of the worm gear and the pinion are different. So the direction of rotation will be on different axes. However, if you mean, the worm gear can rotate in both directions with a helical gear? The answer is "Yes"; worm drives can be built with helical gearing that is either right-hand or left-hand, allowing them to rotate in clockwise or counterclockwise directions. For instance, a right-hand helical gear rotates the worm clockwise or vice versa.
Regarding your second question, if a straight bevel gear has been meshed with two gears horizontally, each of the meshed gears will have an opposite direction of rotation. So if you are looking at the bevel gear from the side, one gear will be rotating clockwise and the other counterclockwise.
I hope we were able to answer your question.
The bevel gear you are describing sounds like a crown gear. A crown gear is a bevel gear taken to the extremes, so it can interface with a spur gear on the perpendicular shaft, rather than another bevel gear.
i like how they made the subscribe button glow
👍
Excellent video, educative and on point.The background sound is a bit too loud, louder than your own voice.
Happy you liked it. Thanks for the tip!
Hello, great! Do you have 3D models to print them?
Hi, unfortunately we don't have the STL files handy for these type of gears. We are planning to add them sometime soon in our membership plan, so you can download them for there. We will inform you as soon as they are ready.
lovely my boy
Thank you very much Sir! 😊

هذا الفيديو رائع جداً
Reply based on Google translation 🙂: Glad you liked it. Thanks for the comment!
what programs are you using, please can you write
We use multiple different software to create these videos and it requires a good skill set to utilize those software. For instance to achieve high accuracy for the gears ⚙️ geometry we 3D modeled them with a CAD software. There are multiple CAD software available in the market (SolidWorks, CATIA, ProE, Siemens NX, etc.). Any of them can be used for this purpose.
I dont know what i have done right but i like it! I watch videos like this, im a pretty good skateboarder, own a 3d printer, play D&D, im really well in shape ,have an active social live and a girlfriend… 😂 i shouldn’t exist
Thanks for watching!
You're right!
Can you please tell me the artist and song name? It's perfect for studying. The video is great by the way.
Have you covered strain wave drives as well as cycloidal disk drives?
Thanks for your comment! Actually, "Strain wave gearing" is a special type of gear, and its working fundamental is very similar to a ring gear. Regarding the "Cycloidal disk," we will be creating a video for hydraulic gear pumps and will cover a similar coupling drive in that video. Our intention for this video is to introduce the most commonly used gears in the industry. I hope we can cover the two other types of gear/coupler in our following videos.
@@CAEPlus ok sweet. I know a fair amount about the 2, but I just wanted to see if there was a video you had produced on the topic. They are a lot less known. I’m excited to see those videos. I’ll make sure I have my notification bell checked for this channel
@Stonedyeet Of course, thanks for following our channel!👍
Hello there. Great video. Very informative. I appreciate the music and was wondering what the name of the music is?
Hi Alex,
Very glad you enjoyed the video! Also, thanks for your nice comment.
Sure, please let me check with our animator and get back to you with the name of the music .
Did you finally manage to get the information about the track name? Superlative video! Excellent explanation and animation and wonderful music!@@CAEPlus
Great video .. U just need to lower the music volume a little bit
Glad you liked it! Sure, we will adjust the background music in our future videos. Thanks for your comment!
very nice.
but how we can make such a video ? I should have to learn graphic design to make such interesting video ?
awesome video, just the music a bit too loud
Glad you liked it. Thanks for the note!
We have reduced the music volume level in our newer videos.
Are elliptical gears still made?
As far as we know, yes, elliptical gears are still made and in use and are an important component in specific mechanical applications where their unique properties are required.
Music is too loud and strictly not necessary. Good video.
Noted! Thanks for your comment.
Please give me your suggestions for the software you used to make such vedioes
Actually, we use multiple different software to create these videos (engineering, animation, graphics design). So each team/person creates their section in the corresponding software, and later we assemble the footage into one part.
Used to be control of valve any
I am not sure if this is a question or just a comment.
Correct, the camshaft function is to ensure the engine's inlet and exhaust valves are operating at the right time, with the exact stroke and in a precisely defined sequence.
👌👌👌
🙏
nice but the background music is way too loud, the voice should be well above the music
Thanks for the feedback. We have fixed this issue in our recent videos. Please check them and let us know if you are happy with the changes.
From a visual perspective, your video is terrific. However, I bailed quickly after tiring of the needlessly loud background music.
wow
Hope you liked it!
Great video but the music is unnecessary distraction. Thank you
Ok, glad you liked the video. Thank you!
Thank you for sharing this video, what is the purpose of the music? DISTORTION
Noted. You're welcome and thanks for your comment!
Your video is very efficient and quality but a little bit occurrence that the background sound is very annoying. It is difficult to concentrate your voice due to annoying background sound
Glad you found the video useful.
Yes, we have took note about the background sound and have adjusted its level in our newer videos.
Thanks for your comment!
The bgm spoiled the narration despite excellent narration
Glad you liked it!
FYI: That’s not a pic of ‘double bevel’ it’s a herringbone (double helical) - matter of fact there’s no such thing as a ‘double bevel’ gear.
Great eyes! 😉We missed the typo. Just fixed it. Thanks for the note! 👍
Spur/helical gear + Ring = {Planetary gear}
Very true! Didn't think of it this way 😉.
