FIELD: mechanical engineering. SUBSTANCE: proposed sectional crankshaft consists of separately made webs of cranks, main journals and crankpins with inner through holes. Main journals and crankpins are installed in antifriction bearings. Elements connecting main journals and crankpins with webs of cranks are essentially layers of connecting material applied to main journals and crankpins of crankshaft. Said material features reversible memorized shape effect. EFFECT: simplified and facilitated assembling of crankshaft, improved strength and increased service life of crankshaft. 5 cl, 1 dwg
