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

Açıklama

This is a parametric double 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°)Pressure angle: 20° (normal)Gear type: Double helical / herringbone (continuous Sykes type, no center groove)Standard: Based on involute gear geometryUse cases:High-load power transmissionThrust-free parallel-shaft gear drivesCNC machinery3D printingMechanical design prototyping⚙️ Generate your own double helical gear (any parameters):https://meta-matic.com/en/3d/double-helical-gear/You can freely adjust:ModuleNumber of teethHelix angleBore diameterFace widthand instantly download a STEP file.Why this matters:Most models here are static.This system allows you to generate exactly what you need.Note:A double helical (herringbone) gear joins two opposite-hand helical halves back-to-back, so the axial thrust of each side cancels out.The module is the normal module; the transverse module is calculated internally as m / cos β.
