bevel gear generator
Bevel gear generator
Make a meshing pair of 3D printable bevel gears at 90°: set the teeth on each, module, face width and bore, then download the STL free.
Need more than sizes?
A hub with a set screw on each gear, a shaft angle other than 90°, spiral teeth, a housing that holds both shafts. Describe it, and Voloom builds it from your sizes.
Good to know
Bevel gears turn a drive through a right angle. Each is cut for its mate: both cones share an apex, so a pair only meshes with the tooth counts it was made with (equal counts make a mitre pair). Keep the face width under a third of the cone distance or the small ends of the teeth get too thin to print. Teeth are 20° involutes thinned by 0.15 mm so printed gears do not bind; the pair is placed at its exact centre distance, meshed.
How it works
- 1Set the sizes. The bevel gear rebuilds when you let go of a slider.
- 2Turn it in the preview and check the overall size.
- 3Download the STL or 3MF, one file per part, and slice it.
What you can change
Pinion teeth: 8 to 60.
Gear teeth: 8 to 80.
Module: 0.5 to 4 mm.
Face width: 3 to 25 mm.
Bore: 2 to 12 mm.
When sizes are not enough
This is a real parametric model, built on a CAD kernel, not a mesh stretched to fit. Walls stay the thickness you set when the bevel gear grows.
For anything the sliders do not cover, such as ports in the right places, mounting holes, text or a logo, describe it to Voloom. It starts from these sizes and builds the part from scratch.
About STL
STL (Stereolithography). The default 3D printing format since 1987: a bare list of triangles. Every slicer reads it, but it has no units, no color, and no parts.
Units: None in the file. Slicers read the numbers as millimeters. Up axis: Z. Opens in Bambu Studio, PrusaSlicer, Cura, OrcaSlicer, and Blender.
Questions
- Is the bevel gear generator free?
- Yes. You get 3 runs a month without an account. Sign in with your email, free, and there is no limit.
- Do I need an account?
- No. Change the sizes and preview as much as you like. Downloads count toward the free runs; signing in, free, removes the limit.
- Can I add cutouts, holes or a logo to the bevel gear?
- Yes. Use “Describe the rest” under the preview. Voloom takes your sizes into a prompt, you add what you need in plain words, and it builds a new parametric model you can keep editing.
- Can I get a STEP file?
- Yes, from the editor. Open your bevel gear in Voloom and download STEP on the Maker plan, for Fusion, SolidWorks or FreeCAD.
