Learn Fusion 360 or Die Trying LESSON 11: Design Gear Box with Stacked Gears for 3D Printing

This video tutorial shows step by step instructions on how to create a 3D printable gear box with stacked herringbone gears. We printed on both a Raise3D and Prusa 3d printer.

I am still with ya on these videos, and my stacked gearbox with herringbone gears - turned out great!

[@samsonaka4058]

Mr. McWhorter, as far as i remember, for the purpose of calculating distance between the centers of the gears there is given a so called pitch diameter. So no need to use outside and inside diameters. Plus, using a pitch diameter you don't need to add a millimeter to avoid jamming of ghe gears. Pitch diameter takes this into account.

I have learned so much working through these videos. Thank you very much Paul for making them. The gear lessons were really interesting. I am so much more confident with Fusion 360 from these lessons.

[@newalla344]

Thank you for the videos, I know you came down to my level, so I could understand what you are trying to teach. I have come a long way after watching them, with a long way to go. Thank you again yes I will be happy to share your videos.

[@martynwimpenny2017]

Another great lesson - only thing is that there is only two more left!

[@chuckwharton3549]

Thanks so much for providing the basic concepts and verbalizing each key stroke. I may be able to do something on my own now. I had same problem as you with the experienced U-Tube instructors (depression and gave up). My experience was on the drafting board and management for a few decades.

[@Walt1119]

Another great lesson Paul! Thank you so much for all your work bringing these to us, I feel so fortunate to have found your lessons, really like learning the Fusion, and can't wait to get my 3D printer! Also looking at your Arduino classes too, want to take those also!!! Thanks again!!!! w.

[@kperalta1701]

On the video at 3:45 you were using the gear parameter "Virtual Teeth" at 26.173 instead of "Root Diameter" of 25.695.

[@brettrosner1895]

Yes, saw that too. It's funny because you want to say something to help, but one would need a time machine and a phone number to do so.

[@mikelsanfelix5722]

exactly, I was yelling at the screen nooooooo, but Paul couldn't hear me

[@neilanderson9137]

Boom and thanks to you Paul I can now use F360. I followed all your lessons and have had a great time learning. Thanks Paul

[@cocfanatix352]

Such a great tutorial series; I really appreciate it. Many Greetings from Germany :)

[@sadqazaria4167]

Thanks for taking the time and redoing the video for us *thumbs up*

[@ernestasvaikasas6528]

Great series, thank you!

[@charlotteswift]

Great video, thanks Paul. Worm and rack and pinion gears look interesting too imho. Last video for a while I hear. Come back soon!!

[@keesvaneekeren7293]

Caution !!! The distance between two gears must be calculated with the pitch circles. Read my comment at lesson 10.

[@joopdewinter6650]

greetings from holland, you are amazing thank you for all your time

[@tomdrought5662]

Loved it. Thank you!

[@gryzman]

couple of comments: - dimensions is something that some commands ask about straight away - so to save time, its best to just put them there. I know that initially this is not good for learning, but few lessons in.. - Rotation - just use the middle button of the mouse, or a keyboard shortcut. Saves you having to escape it. - To move objects closer together - is something that you can do in your slicing software. No need to do it in Fusion :) Great lessons btw ! nice refresher for myself!

[@ThiLI0n]

Hey, thanks for the video. Would you do a video on making herringbone racks?

[@michaelsimons8990]

Great video and practice example. Will you ever go into the automation capabilities of CAM?

[@russbyrer5620]

Paul I love your lessons please keep up the great work. I want to learn Fusion and wean myself from Sketch up Thanks for all you do!

[@paulmcwhorter]

Great to hear!

[@mastergs2]

Hello. Turn off at the preferences->design last position -> 'Auto hide sketch...' to avoid manually turning on sketch after creation. You can close the left 'data panel' to have more space room on desktop. I like watch this kind of films. Thanks.

[@sandeepkumar-by8gs]

thanks a lot

[@woutberggren6192]

Very good presentations, excellent for beginners like myself. FYI: the main reason for helical teeth is to reduce noise; straight teeth connect and disconnect at the same time and thus can produce a rattle. herringbone teeth connect and disconnect gradually and are much more silent. Disadvantage of helical teeth is that axial forces are created which increase the loads on the gear wheels and on the bearings. Heringbone teeth solve this problem. Andre Cirtroen (of the car company) used herringbone teeth in his gear boxes (that is why the Citroen emblem shows two matching herringbones). Could you tell a little bit more about the G-code generator that you use? Many thanks for your excellent lessons.

[@robindriscoll]

I love your videos. FYI. You can turn off hide sketches in your preferences in GENERAL:DESIGN:AUTO HIDE SKETCH ON FEATURE CREATION.

[@donmcdonald4347]

Another wonderful tutorial. I am moving right along with these videos and understand everything thanks to your great teaching. One thing I have seen in Fusion 360 presentations is an entire assembly like this gear box actually assembled and working on the screen in Fusion 360. It would be great to see how to do this by assembling this gear box and spinning it on the screen. As I understand it problems like the posts being too large or gears not meshing properly can be identified by the program and highlighted so that you know where the problems lay. It is this aspect of Fusion 360 that I am most interested in. How do you go about doing this?

[@Krakenhed]

Hi master ;) do we have anything about planetary gearbox?

[@MrIklassen]

I am Printing! Thanks for the Video.

[@paulmcwhorter]

Great!

[@ReneDirks]

Great video series but I still don't understand why you click the dimension away only to tap the D key to dimension. Guess it's something to do with habits... Just tried to loft something, that is quite interesting, maybe a tip for a new episode?

[@arasender]

boom!

[@timvener3723]

Will there be a future video on how to virtually assemble the parts in F360?

[@chuckpickering6040]

Another great lesson! Two questions. What was the reasoning for choosing 12 and 17 teeth for your gears? Odd ratios. Would you show the math for calculating the overall ratio of this design?

[@paulmcwhorter]

No real math . . . just wanted a big and little gear, so get gear reduction.

[@bobbailey7024]

Driven gear divided by driver gear (17 /12) for as many driven and driver gears in the gear train. E.g Driver = 12 teeth and driven = 17 teeth the ratio would be 17/12. As the next 12 tooth gear is fixed to the first 17 tooth driven gear, it becomes the driver for the next 17 tooth gear and so on. (17/12) x (17/12) x (17/12) gives an overall ratio of 2.843171269 : 1. You can also use the pitch circle diameters instead of teeth in the same manner.

[@wardwyseur]

does printing on a raft prevent u of getting a bit of an elephantsfoot?

[@charlotteswift]

If any of you are like me and hate having to write down measurements and use a calculator, you might like to read my comment on lesson 10 before trying this lesson (or you might not)

[@richardriddell4276]

The error in the spacing of the posts came when you copied the wrong diameter down for your gears! Easy mistake to make.

[@utkarshjain8024]

8:29 But you're a mathematician!

[@paulmcwhorter]

There is really a difference between knowing math and doing head math. Like people who can multiply hard problems in their head. I understand math, but work it out on paper.

[@utkarshjain8024]

@@paulmcwhorter true that (BTW, love your videos! I was actually somewhat scared to start working on 3-D designing...your videos are really inspirational!)

We’re well dead now. The third video in a row where you’ve just played with gears. Time to unsubscribe by the look of it.
