Helical gear in Creo Parametric 

Parameter consideration: no_of_teeth = 20 /*any teeth value normal_module = 3 /*any teeth value normal_pressure_angle = 14.5° & 20° /*Standard value width = 20 helix_angle = 26 /*normal_pressure_angle = αn /* transverse_pressure_angle = αt /*helix_angle = β Relations for helical gear: transverse_module = normal_module / cos (helix_angle) pitch_dia = transverse_module*no_of_teeth normal_circular_pitch = pi * normal_module transverse_circular_pitch = pi * transverse_module transverse_pressure_angle = atan((tan (normal_pressure_angle))/(cos(helix_angle))) addendum = normal_module dedendum = 1.25*normal_module outer_dia = pitch_dia+(2* addendum) root_dia = pitch_dia - (2 * dedendum) base_dia = pitch_dia*cos(transverse_pressure_angle) normal_teeth_thickness = normal_circular_pitch / 2 transverse_teeth_thickness = transverse_circular_pitch / 2 lead = pi * pitch_dia / tan (Helix_angle) root_fillet = 0.38*transverse_module semitopping = 0.1*transverse_module Involute equation: theta = t*90 base_radius = base_dia/2 cir_len = (pi * base_radius * t ) / 2 X_PNT = base_radius * cos(theta) Y_PNT = base_radius * sin(theta) x = X_PNT + ( cir_len * sin(theta) ) y = Y_PNT - ( cir_len * cos(theta)) z = 0

Literally very much useful sir thanks for the parametric formula, i have made both gears by ur method and done absolutely perfect with animation ☺️

gears and turbine/compressor/fan blades are one of the most technical design models in cad

great mind comes with great knowledge.

Great Explanation and knowledge base. Would like to know how do we add addendum modification coefficient to this model as this factor is considered in gear specific software like Romex

Is there a way to add the helical sweep direction, LH or RH, to a family table? This would allow the ability to family table the gears all in one family table.

Thank you sir

Thankyou 🤗🤗🤗🤗

super sir

Hello please make video on sieve web belt sprocket

very thank sir

Please make video on all bevel gear design using creo

amazing 💞

Amazing !!!!!

Hello, if we wanted to modify the formulas and relations to make an internal helical gear (for a planetary gearbox ring gear), how would we do that?

Jay Hind Sir Satyendra Sir, Please make a video on Gear Box

sir please explain the curve equation.

Please video on worm gear

SIR ,WHEN CHANING THE TEETH DIRECTION FOR HELICAL GEAR 2, THE PROCESS FAIL TO OCCUR,, HELP ME

How to design an internal helical gear in creo?

I drew that with Blend !! Is it ok ..?? Please guide..

Sir... Do we need to make some changes in formulae while designing helical gear with modified addendum correction? If so please guide me.

Make video on warm gear please

Sir Can you please make a video of shrinkwrap part file and shrinkwrap feature

You can start an online class for learners....

Do you know how this flat gear is drawn? cdn-adffp.nitrocdn.com/crbUCoDsRphTMSdwYVBXyPMAWsKkoBOp/assets/images/optimized/rev-228bac1/wp-content/uploads/2021/10/fishing-reel-gear-ratio.png
