Slider-crank mechanism for long stroke 3

Crank length: a Conrod length: b Eccentricity of the slider crank mechanism: e (distance between rotary axis of the crank and line tracing by a point on axis of the slider pin) Key factor for this mechanism: e = b – a Stroke length of the slider: L = (a.b) So theoretically, with a given crank of constant radius a, it is possible to get the stroke length L as long as desired by increasing the conrod length b. If b = a; L = 4a See: Here: a = 30 ; b= 60 ; L = 1
