Cutter Diameter Spiral Bevel 2

[mfgenggear]

Hi All hope all is good.
I looking for calculations for spiral bevel gears , figure out the cutter diameter required.
and also good programs that can create the model with out paying an arm and leg.

Good to be back

Hi Mfgenggear
Good to have you back; I hope all is good with you.
Here's a source I find to be excellent:

https://books.google.pl/books?id=La...g 2.3 Bevel gear geometry calculation&f=false

And the cutter diameter:

Hope it helps.

Hi Spigor

Thank You kindly for that info..
maybe would it be possible to save me time and do you know the formulas.
for cutter radius
cutter center distance.

this is for my own knowledge ..
I will be corresponding with Klingeinberg & gleason..

Mean while I will be reading the books you provided.

Very Truly

mfgenggear,

ANSI/AGMA 2005-D03 has all the equations you're looking for. Also includes calculation methods (section 6) and standard cutter sizes (app. C) for specific manufacturers (Gleason, Klingelnberg & Oerlikon). Definitely worth purchasing a copy.

GearTrax does a very nice job modeling spiral bevel gears with SolidWorks or Inventor. License costs about $1300.

Hope that helps.

Hi Terry
Hope all is well thank you for the Tip.
I am semi retired. but I have come out of retirement.

Well, nowadays the cutter diameter is optimized to the application and manufacturing method. So it is not really a single formula, you could see how it is done in the sources we have quoted. But the old rule was that the cutter radius should be similar to the mean cone distance Rm. The formula to get that is:

m z2
Re = ---------
2 sin(S2)

where S2 is the pitch cone angle of the gear, m is the outer transverse module and z2 is the number of teeth in the gear

B
Rm = Re - -
2
where B is the face width

Before that there was an even older rule that the cutter radius should be similar to the outer cone distance Re.

Hope that helps.
Out of retirement?
