SpurMesh Gear Calculator

SpurMesh is an offline mechanical engineering tool engineered for machinists, robotics mentors, mechanical engineers, and 3D printing makers who need reliable gear geometry calculations in workshop environments. Designed specifically for hands-on fabrication, SpurMesh operates entirely on-device without cellular connectivity, mandatory cloud logins, or recurring subscription fees. Calculate critical spur gear dimensions directly at the machine tool or workbench. Key Engineering Features: - Pitch & Module Conversions: Seamlessly convert between diametral pitch (DP), metric module (m), and circular pitch (CP). - Gear Geometry Solvers: Compute pitch diameter, outer diameter, root diameter, addendum, dedendum, and tooth thickness in standard and custom pressure angles (14.5°, 20°, 25°). - Center Distance & Meshing: Determine exact shaft center distances for mating gear pairs, including backlash allowances and clearance margins. - Gear Ratio Analysis: Evaluate single-stage reductions, velocity ratios, and contact ratios to verify smooth mechanical mesh. - Android Share Integration: Share computed gear specifications directly with teammates via standard Android share targets, CAD messaging channels, or workshop logs. - Workshop Ready: Works completely offline in fabrication shops, machine bays, and field service locations with zero latency and no cloud dependencies. - Privacy First: Operates with zero user tracking, analytics trackers, or account requirements. Built for high-precision workflows in robotics fabrication, rapid prototyping, and manual machining.
