This involute gear generator is an free online tool used to create precise gear geometries for mechanical systems. Gears are essential components in machines because they transfer motion and torque between rotating shafts.
The most common gear type in engineering is the involute gear, which is based on a mathematical curve that ensures smooth meshing and constant velocity transmission.
This gear generator allows you to create custom spur gears and export them as DXF or SVG files for CAD software, CNC machining, laser cutting, 3d printing and 3D modeling.
The exported 2D curves contain only arcs (for tip and root circle) and high precision splines (DXF) or Bézier curves (SVG) - no faceted polylines approximations.
The tool calculates the exact tooth profile based on the input parameters and generates a precise and accurate 2D representation of the gear.
The key parameters define the basic shape of the gear such as size or diameter and affect operating forces.
The additional parameters define the detailed shape of every teeth such as height, width or solidity
All these values define the geometry of the gear and ensure correct meshing between connected gears.
DXF is widely used in CAD and CNC manufacturing. It is ideal for precision machining and industrial production. Typical applications include:
SVG files are vector graphics commonly used for laser cutting and digital fabrication.
The generated gears can also be used for 3D printing projects. By importing the SVG or DXF file into CAD software, you can extrude it into a 3D printable model.
Typical applications include robotics prototypes, custom gearboxes, replacement parts, and educational mechanical projects.
Because of these advantages, involute gears are used in automotive systems, industrial machines, robotics, and consumer products.
Simply enter your desired parameters, preview the generated gear, and export it as DXF or SVG. No download and no installation is required — everything runs directly in your browser.
