ABSTRACT:
Method of deep-rolling of crankshaft pins by applying different rolling forces over a rotational angle (phi) of 360.degree., such as to produce in each angular position a constant enlargement of the angle (alpha) subtended by the mirror faces i.e. the faces connected with the respective transition radii to provide, at least, in the angular region most subject to damage the desired fatigue strength increase.
