Treadle with Cord and Pulley: Ideal Diameter Comparison
Compare effective driver and driven pulley diameters, circumferences and ideal speed ratio. Actual RPM requires a shaft-speed input and real transmission behavior.
Treadle to Disk via Connecting Rod: Ideal Geometry Comparison
Explore a treadle-and-pitman arrangement beside a simplified in-line slider-crank angle comparison. The calculation does not solve the full treadle linkage.
Spring-return Treadle to Pulley Mechanism: How It Works, Parts, Diagram, and Uses Explained
Spring-return treadle to pulley converts foot strokes into shaft rotation via a crank and return spring. Sizing, formulas, and real workshop examples.
Crank with Treadle Mechanism Explained: How a Foot Pedal Drives Rotary Motion, Parts, Diagram
Explore a foot treadle, pitman and crank. Calculate target foot stroke, crank throw, pitman ratio and peak downstroke torque for the stated mounting geometry.
