## What is GearMesh Backlash Lab?

GearMesh Backlash Lab is a paid, local-first metrology desk for spur and helical gear pairs. Enter module, tooth counts, pressure and helix angles, profile shifts, center distance, and target backlash. Calculate transverse module, pitch diameters, ratio, nominal center, center delta, and a backlash-centered shim direction estimate. Record readings by station with temperature, indicator load, and notes; compare mean and range. Audit geometry, coverage, backlash band, runout, and center distance. Export JSON or CSV and duplicate revisions. No login, IAP, ads, analytics, tracking, cloud, AI, or backend. Verify changes against manufacturer tolerances and contact pattern.
