Creating a helical gear with pa>29deg

Question asked by Jamie Brown on Sep 8, 2013

Am trying to create a helical gear using the toolbox feature with the following parameters:

 

Diametrical pitch - 2

# of teeth - 31

Helix angle - 12deg

Pressure angle - 35.3deg

Face width - 6

 

The issue is that the program is having issues cutting the teeth with these parameters. i can only get a 29deg pressure angle. Anybody know why this is so and any way around it?

If i reduce the number of teeth, i am able to go a little higer in pressure angle.
