CRANKSHAFT

摘要

FIELD: mechanical engineering; heavy-duty machines in rolling. SUBSTANCE: crankshaft has bearing journal and crankpin located at eccentricity and overlapping; they are connected by means of cheeks having convexo- convex form; one surface is concentric relative to surface of bearing journal and other surface is concentric relative to surface of crankpin. Thickness does not exceed amount of radial overlapping of these checks. Crankshaft may be mounted on crankpin of bearing of optimal diameter. EFFECT: enhanced reliability. 2 dwgt
