Involute vs. V-Splines

Involute vs. V-Splines

Involute vs. V-Splines

(OP)
   
 
I am interested in opinions regarding choice and application of involute vs. v (e.g. 70 degree) splines.

Are v-splines self-centering as with involute?

Are v-splines any cheaper to machine?

As well, does anyone know of v-splines in common use in say driveshafts or couplings?

RE: Involute vs. V-Splines

I'm not sure I've ever seen a V-spline, though I'm sure it's possible to make them.

As for machining, they would be about the same.  But in production, nobody machines involute splines; they are ROLLED, very quickly, by squeezing a round blank between sliding toothed plates.  Just like you make a clay cylinder between your palms, but with a little more force involved.

RE: Involute vs. V-Splines

Involute splines are rolled if little
guys but are cut for larger modules or
smaller diametral pitch.  I think only
because the involute spline is common
that they might be more cost effective
as the tooling is readily available.
It might be better if you had posted this
to the gear and pulley section.
An involute spline is just a special
stubbed gear.
