Parametric Helical Gear Generator (STEP, Customizable, CNC & 3D Printing)

This is a parametric helical gear model generated using an automated CAD system.

Unlike fixed models, this gear is not a one-off design — it can be regenerated with different parameters.

Specifications of this model:

Module: [X]

Number of teeth: [X]

Helix angle: [X]° (5–45°)

Helix direction: Right-handed / Left-handed

Pressure angle: 20° (normal)

Standard: Based on involute gear geometry

Use cases:

Smooth, quiet power transmission

Parallel-shaft gear drives

CNC machinery

3D printing

Mechanical design prototyping

Why this matters:

Most models here are static.

This system allows you to generate exactly what you need.

Note:

Helical gears mesh more gradually than spur gears for smoother, quieter operation, but they also generate axial thrust.

The module is the normal module; the transverse module is calculated internally as m / cos β.
