Helical Gear · 模型 137331
From The Tutorial - https://www.youtube.com/watch?v=-7mgUi4_jSQ First time tried. Very excited, Parametric design. Parameters:- No_Of_Teeth - 32 Normal_Module - 2.8 Pitch_Diameter - 100 Normal_Pressure_Angle - 20 Helix_Angle - 26 Width - 25 Helical Gear formula:- Transverse_module = normal_module / cos (helix_angle) Normal_circular_pitch = pi * normal_module Transverse_circular_pitch = pi * transverse_module Transverse_pressure_angle = atan((tan (normal_pressure_angle))/(cos (helix_angle))) Outer_Diameter = pitch_diameter + (2 * normal_module) Root_diameter = pitch_diameter - (2 * 1.25 * normal_module) Base_diameter = pitch_diameter * cos (transverse_pressure_angle) Normal_tooth_thickness = (pi * transverse_module) / 2 Lead = pi * Pitch_diameter / tan (Helix_angle) Involute curve Equation (Cartesian Coordinates):- Base_radius = Base_diameter / 2 Angle = t*90 Cir_len = (PI * Base_radius * t ) / 2 X_PNT = Base_radius * cos(Angle) Y_PNT = Base_radius * sin(Angle) x = X_PNT + ( Cir_len * sin(Angle)) y = Y_PNT - ( Cir_len * cos(Angle)) z = 0
