View Full Version : Cutting involute splines in a coupling hub

07-18-2003, 06:25 PM
[1]Could someone please advise me on how to cut 30 degree involute splines (9 teeth 20/40 DP, major diameter 0.500" )in the bore of a carbon steel flexible coupling hub.
This is a "one off" application to drive a small hydraulic pump (SAE AA PTO pad)
I have a vertical mill and a rotary table.
[2]As an alternative is there a source for 0.500" splined bore spider type couplings?
What I have seen so far does not go below a
0.625" spline size
Thank you.
