Import Surface

• standard library: import simplecadapi as scad then scad.std.gear.make_helical_gear_rsolid(...); direct submodule import: from simplecadapi.std.gear import make_helical_gear_rsolid

Description

Create an involute helical gear.

Non-zero helix angles use a continuous twisted sweep along the gear axis. An auxiliary-spine rotation law preserves the profile while generating one continuous side face per profile edge instead of one face per loft interval.

Parameters

n_teeth

• Type: int
• Description: Number of teeth (>= 3).

module

• Type: float
• Description: Gear module in mm.

pressure_angle

• Type: float, default 20
• Description: Pressure angle in degrees.

helix_angle

• Type: float, default 30
• Description: Helix angle in degrees.

gear_height

• Type: float, default 8.0
• Description: Gear thickness along Z in mm.

addendum_factor

• Type: float, default 1.0
• Description: Tooth addendum as a multiple of module.

clearance_factor

• Type: float, default 0.25
• Description: Root clearance beyond the addendum, as a multiple of module.

backlash

• Type: float, default 0.0
• Description: Circumferential tooth-thickness reduction at the pitch circle in mm.
