CRANKSHAFT AND METHOD OF ITS MANUFACTURE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; internal combustion engines and other machines and mechanism containing main journals and crankpins connected with cheeks through fillets. SUBSTANCE: reliability and operating properties of conjugated crankshaft journal and thin-walled rolled replaceable split bushing (or half-ring) with shaped or cylindrical surfaces are improved by provision of rigid fixing of bushings or half-rings relative to journals by means of special locking half-rings. Bushings or half-rings are installed in circular fillets undercut to cheek and are additionally pressed by screws over of thin-walled bushings. To dismount locking half-rings special are made in cheeks. Inner surfaces of rolled bushing or half-rings can be coated with glue. EFFECT: improved reliability and operating properties of mated crankshaft journal and thin walled split bushing. 10 cl, 28 dwg
