involute gear drawing
involute gear drawing
(OP)
yes i am new to auto cad and engineering in general. I am updating drawings for a turboprop motot and have to draw some involute gears that were drawn in the 50's
i have internal splines that dont give the the base diameter and they want them drawn like a external spline. can anyone help me in finding a web site that will show exactly how to draw involute splines. Or is there anyone out there that can explain it if i give the number i have to you.
Ahead of time thanx to all of you out there.

The demo will allow you to draw a 25T spline only but once drawn you then have a standard to work to.

If you know the cutting/checking data for your splines (they have to be a part of the old drawing) then the rest is just some math and programming. I can create for you the 2D dxf file for such spline (without root fillets, you can add it easily), then you can extrude it to create 3D solid model. I do not use ACAD, I can not create dwg file. If you want it, tell us:
No. of teeth
Module ( or Diametral Pitch)
Pressure angle
Major dia
Root dia

1. the tooth thicknes/space (circular) and the diameter where it is measured, or the size over/between pins
For helical gears I need also the helix angle, but this is not your case.

have free software downloads (40 day trial basis only), for both involute gears and splines. Hope it helps.
