Most high-end CAD software includes a "Toolbox" or specific gear generator add-in. These are best for integration directly into an assembly file. They allow for instant insertion of mates and constraints.
A: Theoretically up to 45°. Above 45°, axial thrust becomes enormous, and the gear becomes a "cross-helical" (screw gear) with very low efficiency. helical gear generator
The generator automates these calculations, outputting a 3D model or a profile that can be manufactured. Most high-end CAD software includes a "Toolbox" or
: Easily switch between Left-Hand (L) and Right-Hand (R) gears to ensure a perfect mesh. axial thrust becomes enormous
