The invention relates to a crank and connecting-rod assembly converting the straight reciprocating motion into rotational motion, particularly applicable to endothermal reciprocating engines The assembly comprises a roller (2) or a rotating connecting rod (7) loosely mounted on a bolt (3) and a cam (1) forming one piece with an outer shaft (6), which has a peripheral profile composed of at least two circle segments or arcs for optimizing the working cycle strokes, the roller (2) following the profile of cam (1) in a mere slide free and consequently wear free rotational motion
