CRANK MECHANISM SYSTEM FOR THE TRANSFORMATION OF RECIPROCATING LINEAR MOTION INTO ROTARY MOTION, PARTICULARLY SUITABLE FOR RECIPROCATING ENDOTHERMIC ENGINES

摘要

The present invention relates to a crank system for thetransformation of reciprocating linear motion into rotary motion,particularly suitable for reciprocating endothermic engines, comprising awheel or rotating connection rod (2), idly provided on the engine piston (5)pin (3), and a cam (1), provided on the output shaft (6), having aperimetric profile made up of at least two segments or cam arches for theoptimisation of the engine cycle strokes, said wheel (2) rotating along theprofile of said cam (1) with a coupling characterized by the absence offriction or by a minimum friction.
