The curve diamondjim created is right. If you want it more accurate, just set the variant "pnts" bigger.
There are several involute equations, his is right.
Here below I attached a lisp file which creates involute curve only, it can also create "short" or "long" involute, that means: the curve...
I am working on a surface which a 3D curve revolves along another straight line, and I want cut this surface with a plane to see the intersection.
But solid can not do the job.
Hi, Gearman
The gear we cut with shaper was an internal ring gear, after resharpening (like you said, it was to certain nagative value), the root diameter got smaller, the tip of planetry gear hit the root.
The shaper cutter had a too big tip relief angle. here below is my post about this...
Hi, ERT
Thanks for your concern, and your advice.
I am an assembly processsing engineer, designing tools to assemble gear boxes. Our factory makes spur and helical gears. I think to understand gear by geometry is the base of all other respects.
And all respects of gear are associated: too thin...
Gear transmission is the transmission of two partial spheres which have their own centers and axles.
I believe the spur gear is the particular condition of bevel gear, when the apex is at the infinite distance and the shaft angle is 0. So equations for bevel gear can be used for spur gear.
So I...
I believe that will be the same as press lock and press release, just inverse the direction of it.
You can see a kind of ball pen anyway, press the tip out, and press the tip back. disassemble it and see what's inside.
