This online tool simplifies the creation of involute gear profiles. Specify the number of teeth, module, and fine-tune parameters like clearance and backlash. The tool then generates accurate gear profiles based on the input and allows users to download them as DXF files for seamless integration with CAD software.

Basic Lewis bending estimate for the active gear. Geometry values come from the gear generator above.
This calculator provides a simplified Lewis bending estimate for spur gear tooth-root stress. It accepts either transmitted torque or tangential force at the pitch circle, converts between them using the pitch diameter, assumes the load is represented by the optional service and distribution factors, and assumes the selected Lewis form factor is appropriate for the tooth count and pressure angle.
The pass/fail result compares calculated bending stress against the entered allowable bending stress and target safety factor. It does not replace a full AGMA or ISO gear rating and does not check contact stress, pitting, wear, scuffing, fatigue life, lubrication, heat treatment, rim thickness, shaft or bearing deflection, manufacturing quality, or detailed dynamic effects.

Barth velocity factor is disabled, so rotational speed does not affect bending stress.
