CHECK OUT THE COMMENTS BEFORE LOOKING AT THE VIDEOS

BUT THE 3D METHOD LOOKS OK !!!!!

Hello carlosban71, if you really need the geometry and resistance formulas it's all on the internet, provide you succed in 'reading' the documents; maybe this is only for the companies that fabricate them but try and search for example:

By subjects :

gleason shaft formulas or spiral bevel calculations

By documents ( PDF ) :

9.8_Calculation-for-Gleason-system-Straight-bevel-gear_TechnicalData_KGSTOCKGEARS

Calculation of Gear Dimensions _ KHK Gears

19830011869

19910021223

And so more ...

So carlosban71, have you done your searches on the Internet, your AutoCAD tests, etc...

There is so much to see on the internet....

Hellocarlosban71, please tell us if you want to draw an APPROXIMATE 3Dmodel of it or the real one.

Ifit's an approximate model I'm afraid it's already going to bedifficult but if I had to do this I would base my concept on theimage here enclosed that is the calculation for : CYLINDRICAL STRAITCUT GEARS and try to make them conical and helical!!!

Igive you this extract of an EXCEL file of mine that I use to drawgears but it's only giving the general dimensions; what is missing isthe ' radius' ( because it's not a radius but a 'developpante decercle' in french ) of the sides of the gears.

Youalso have the link to the CAD Studio TIP 4724 : Involute curvesfor gears just above.

Apply these formulas,

Is this formula good for this type of gear?

I would like to know the calculation why they are of the Gleason type, otherwise I need data and I also calculate the formulas

N=NUMBER OF TEETH

DE=EXTERNAL DIAMETER

Formulas

M= Module= DE/N+2

Dp= Primitive Diameter= M x N

CT= Plot Diameter = 0.96592 x Dp

P= Diametral passage= M x Pi

Di= Internal diameter = Dp-(2M x 1.167)

R1 = Tooth tracing 0.07 x Dp

R2 = Tooth tracing 0.22 x Dp

R3 = Tooth tracing 0.33 x Dp

R4 = Tooth tracing detalle 0.3 x M

Franco's Angle = 90 £/ N
