MECHANISM DETACHABLE CRANKSHAFT AND ITS ANTIFRICTION BEARINGS Russian patent published in 1998 - IPC

FIELD: mechanical engineering; internal combustion engines; piston machines. SUBSTANCE: crankshaft is divided into parts with their subsequent fastening by attachment bolts after fitting of antifriction bearings onto main journals and crankpins of crankshaft. Crankshaft webs are connected with journals. Limiters are installed between webs. Crankshaft plates form stack inside which crankpin with antifriction bearings is placed.
