FIELD: mechanical engineering. SUBSTANCE: elements of crank cheek and journals are heated up to 600-700 C on both sides of fillets to depth and width of (3-5)R for crankpins and of (6-7)R for main journal, where R is radius of fillet. Section of crankshaft is deformed at this temperature under press by multiple bend. EFFECT: improved straightening capabilities. 4 cl, 1 tbl, 1 dwg
