How To Design Herringbone Gears in Solidworks for 3d Printing

[@davidg.3249]

Dave great job putting together this video it really helps that you walk through the equation bits slowly and pass through some of the basic things quickly. Thank you!

[@designbydave]

Glad to hear it was helpful.

i've been looking for a tutorial like this for so long i had given up on the project, thank you so much

[@designbydave]

Glad to help!

One way to link the equation for Twist Value to your equations is to enter a dummy value while creating the sweep feature and then to edit the dimension in the graphics area by double clicking the feature. That will bring up the normal dimension editing window which accepts equations. Alternatively, I believe you can type the dimension name into the Equations dialog. In my case this was "D4@Sweep1" Thanks for the tutorial. Found a lot of tutorials that didn't include Involute, or used poor modeling practices. This was really well done.

I'll have to check that out thanks!

This is very professional!! And tnx for the info and link

Glad you like it!

This is great content! Thanks for including the equations in the description in addition to the file link. I can't tell you how many times I've gone to get a critical file for a tutorial and it's a dead link. For the raft, as long as you have good surface adhesion, you can always specify an elephant foot offset in all slicers. In Orca, you can even specify a number of layers to adjust for it. Just a thought, if you do run into an application where your bottom surface needs to be aesthetically pleasing.

Funny you should mention that because currently my web site is broken and I haven't had a chance to fix it!

MechE here, great tutorial. I am working in imperial and am using your guide to get myself up to speed on making smallish (.5-8") herringbone gears for a mechanism I am designing for work. The TwistAngle keeps coming out wonky....like for a diametralpitch of 12, 35 teeth, pressure angle 25, .5" thick and yes I did check to make sure that the angular equation units is set to degrees. Any thoughts?

[@designbydave]

It gets a little tricky and I think the equation i supplied doesn't work in your case. That could use some tweaks. Check this explanation of the theory and you should be able to figure it out. - kzbin.info/www/bejne/qJabXp6Pj8-dr7s Also, if you'd like to discuss further, I've setup a discord server to work on things like this discord.gg/PRC44Wu8

great topic, thanks 👍

Thanks for watching

[@svenkrause3433]

Thank you very much!🙃👍

You're welcome 😊

out of interest, you mentioned adhesive for the hub, but didn't mention what you use - I was not sure what you think works best on the metal-to-3dprinted piece ?

[@designbydave]

3M DP420 is my go-to adhesive of choice for this application. It is rated for metal to plastic bonding. Also commonly used in composites. It's good stuff. Of course, expensive though.

[@Poundy]

@@designbydave ah cool - and of course, unobtanium in Australia :)

[@designbydave]

@@Poundy There are other, similar products out there, from the Loctite brand for example

Great tutorial thank you
