E02. Eccentric Slider Crank Mechanism
full metadata

The slider-crank is a basic mechanism to convert circular motion into oscillating linear motion or vice versa. The eccentric-slider is a topological cousin to the slider-crank in that it has four links, one sliding joint and three cylindrical joints. In the E series of models, Reuleaux created seven variations of this kinematic circuit by changing the ratio of the diameter of the cylindrical joints to the lengths of the links. Reuleaux called this variation “pin expansion.”
