Yes well I knew I was over my head when I saw the long addendum and all the gear generating software at my disposal blew up. There is no existing drawing that shows the theoretical new tooth profile. I thank you all for your input and I have already contacted a gear manufacturer about a DXF profile.
What I'm hoping to achieve is to simulate the movement of the teeth in mesh to try and determine why they are vibrating, possibly due to gear wear & root depth. It is suspected that the pinion flank is being hit upon engagement.
Thank you all for the information.
The gear actually has 216 teeth. I have aCAD & Inventor so I can model the gears and then do an analysis. I suspected the tooth thickness was increased.
Thank you for the quick replies;
I have little experience developing gear profiles, especially non-standard ones. The mating bull gear has 216 teeth and the pinions outside diameter is 20in. I don't have the diameter for the bull gear but I have approximated a working depth of 2 1/8in.
What I...
I'm trying to get an involute profile for a non-standard pinion that turns a rotary kiln for a pulp company. The given information I have is:
Outside D = 20in
Diametral Pitch = 1
# of teeth = 17
Pitch Diameter = 17"
150% High addendum
Pressure Angle = 20°
Center Distance = 116.5in
The long...
