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 |

If
it's an approximate model I'm afraid it's already going to be
difficult but if I had to do this I would base my concept on the
image here enclosed that is the calculation for : CYLINDRICAL STRAIT
CUT GEARS and try to make them conical and helical!!! I
give you this extract of an EXCEL file of mine that I use to draw
gears but it's only giving the general dimensions; what is missing is
the ' radius' ( because it's not a radius but a 'developpante de
cercle' in french ) of the sides of the gears.  You
also have the link to the CAD Studio TIP 4724 : Involute curves
for gears just above.

So carlosban71, have you done your searches on the Internet, your AutoCAD tests, etc... There is so much to see on the internet....

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 ... |

CHECK OUT THE COMMENTS BEFORE LOOKING AT THE VIDEOSBUT THE 3D METHOD LOOKS OK !!!!!
