Great minds think alike! 😉 Our team is working around the clock for the past two months on a video about bearings. I appreciate your suggestion and rest assured, it's already in the works. Our estimated time of upload on UKposts is Aug 1, 2023. 🤞

Cheers! 🙂

Cool, happy you found them interesting. Thanks for your visit!

You're welcome! I'm glad you found the information helpful. Best of luck with your exam! ✌

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 ukposts.info/have/v-deo/nJ17fG5rfaSCwmw.html

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!

You're very welcome! Glad you liked it.

Thanks for liking!

Many thanks!

Definitely, with your support 👍. Thanks for your comment!

Glad you you liked it!

You're welcome! Glad you liked it.

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.

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!

Glad you enjoyed. Thank you!

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

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!

Glad you enjoyed it!

Thanks for your kind words! Really glad you liked it.

@@CAEPlus Maybe if you eliminate the background music?

Thanks for the information!

Glad you liked it! Thanks for your nice comment :-).

Happy you liked the video! Next time we will adjust the music level. Thanks for your comment, though.

Reply based on Google translation 🙂: Glad you liked it. Thanks for the comment!

Thank you very much Sir! 😊

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.

Thank you!

Glad you liked it! Sure, we will adjust the background music in our future videos. Thanks for your comment!

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.

We are thrilled to hear that our video has sparked your interest to the point of taking notes! 😊

Thanks for watching!

You're right!

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.

Noted. You're welcome and thanks for your comment!

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.

Glad you liked it. Thanks for the note! We have reduced the music volume level in our newer videos.

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!👍

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!

👍

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.

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.

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.

Ok, glad you liked the video. Thank you!

Noted! Thanks for your comment.

Yes, we covered the types of gear in the beginning (as you mentioned) and then went through some of the gear design fundamentals. In the video's last section, we explained the application of each gear in a real engineering device.

Great eyes! 😉We missed the typo. Just fixed it. Thanks for the note! 👍
