How to model this splined shaft?

Anonymous · ‎02-03-2018

Hi all - I am new to Fusion 360. Had been using Solidworks 2013 year and year ago, but have since fallen out of practice. I have read a number of tutorials on spur gears and such but I can't figure out the best way to model this part. I've attached a picture. The absolute OD (the tip tips of the splines) is 21.40mm and it has 66 splines which is very, very fine. This is to mesh with a handle and not another spline/gear. Also, the thread down the center is also unimportant for the time being.

I can sort out the other details but the splines are annoying me!

Can anyone make suggestions for a newcomer on how to lay this out?

Thanks!

Can you File>Export and then Attach your *.f3d file here?

I would do an Extrude and pattern or a Sweep and pattern - just like in SolidWorks.
