Power Transmission Calculators
Plan gear reductions and chain drives, then generate laser-cut sprockets, spur gears, ring gears, racks, cycloidal drives, and pin gears as STEP, DXF, or SVG files. Each tool runs in the browser, shows its assumptions, and works without a sign-in or download.
Chain Sprocket Generator
Size an ANSI roller chain sprocket, check chain speed, and download a laser-cut plate version as STEP, DXF, or SVG or order it from Fabworks.
Open calculator
Spur Gear Generator
Draw an involute spur gear and its mate from module or diametral pitch, tooth count, and pressure angle, then download STEP, DXF, or SVG or order them.
Open calculator
Motor & Gear Ratio Calculator
Size a motor and gear train for a target speed and torque, or for a mass or inertia you need to accelerate. FRC mode adds motor presets and a gear catalog.
Open calculator
Roller Chain Length Calculator
Find the roller chain length in links for a center distance, or the center distance for a link count, with wrap angle and ratio.
Open calculator
Internal Ring Gear Generator
Draw an internal ring gear and its mating pinion from module or diametral pitch, tooth counts, and pressure angle, then download STEP, DXF, or SVG or order both.
Open calculator
Gear Rack Generator
Size a gear rack and its pinion from module or diametral pitch: rack length, travel per turn, and linear force, then download STEP, DXF, or SVG.
Open calculator
Cycloidal Drive Generator
Size a cycloidal reducer from ring pin count, pin circle, pin size, and eccentricity, then export the disc, pin ring plate, and output plate as STEP, DXF, or SVG.
Open calculator
Pin Gear & Lantern Gear Generator
Generate a gear that meshes with round pins on a laser-cut pin wheel or pin rack, then export STEP, DXF, or SVG or order it.
