Gears are circular devices with teeth that transmit rotation across axes. Gears can change output speed by meshing teeth of different sizes. Gear ratio is calculated as input speed divided by output speed
Bevel gears transmit motion between intersecting shafts on conical blanks. Straight bevel gears are most economical, used up to 1000 fpm. Higher speeds can be achieved with finishing operations
Bevel gears have conical tooth-bearing faces and intersecting shaft axes. Most commonly mounted on 90-degree shafts, but can work at other angles. Pitch surface is cone-shaped, pitch angle is angle between face and axis
Worm drive combines worm screw with worm wheel for perpendicular motion translation. Invented by Archimedes, possibly during First Punic War. Gear ratio equals worm wheel tooth count to one. Drive axes are at 90° angles
Mechanism transforms input forces into desired output forces and movement. Mechanisms consist of moving components like gears, belts, and linkages. Franz Reuleaux defined machine as combination of resistant bodies for work
Generates DXF and SVG files for spur gears and rack and pinion sets. Accepts CNC routers, laser cutters, waterjets, and CNC plasma tables. Uses involute tooth form only, not cycloidal or triangular forms. Includes live visualization and CAD/graphics software compatibility
