Gear System Simulator

Five gears in a chain. Change radii or teeth and drive the first gear.

Gear parameters

Adjust each gear's radius (m) or teeth count. Positions update so gears stay meshed.

Drive angular velocity (rpm) for Gear 1

Simulation time step dt (s)

Overall ratio: 1 : 1

Note: adjacent gears invert rotation direction.

Drag any gear to reposition (will keep contact); double-click a gear to lock/unlock its radius.

Physics: frictionless rolling contact (no slip). Angular speeds propagated by gear ratios.
