PART BREAKING METHOD

摘要

FIELD: mechanical engineering, in particular, breaking of pivoting bearing ring and bar type part billets. SUBSTANCE: method involves creating increased stress concentration zone on part surface; applying loading creating bending moment to part. Value of bending moment is determined on the basis of tensile stress not exceeding part material elastic limit. Method further involves exciting ultrasonic vibrations in part. EFFECT: increased efficiency and simplified method. 3 dwgy
