Gears are such an incredible invention! They're fundamental in so many machines and devices, from watches to cars. It's fascinating how different types of gears can be designed to suit specific applications, each one playing a crucial role in making things work smoothly and efficiently. The science and engineering behind gears really showcase human ingenuity and our ability to solve complex mechanical problems. It's always exciting to learn about the basics and see how these components have evolved over time to become essential in our daily lives! 🌟👏🏼💡
Overall, this is a highly informative and enjoyable video for anyone interested in engineering. It showcases your talent and expertise while providing valuable insights and inspiration to fellow enthusiasts. Keep up the great work, and I look forward to watching more of your content in the future 👍👍👍
Wow! Thank you for this great video. i am working a transmission project where i have to calculate the gear dimensions and gear placements from scractch. This video provided good intro
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?
@@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?
Excellent and you're very welcome! 🙂 We are glad it was helpful to you in your machine design studies. If you have any more questions or need further assistance, please feel free to contact us.
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 TH-cam is Aug 1, 2023. 🤞
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. 😅
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!
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.
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
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!
@Boyd Pennington Of course, we check our videos before posting them on TH-cam 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.
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
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.
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
