ASSEMBLING-DISASSEMBLING ICE CRANKSHAFT Russian patent published in 2017 - IPC F16C3/12 

FIELD: mechanical engineering.

SUBSTANCE: dismountable crankshaft comprises two coaxially main journals (3, 10) and a root sleeve (8), two crank neck, made in the form of rod sleeves (7, 9) connected with two main journals (3, 10) and root hub (8) through the cheeks (6a, 6b, 6c, 6d) and fixed against rotation therein. The retainer is in the form of at least one projection disposed on the end surfaces of the necks (3, 10) and bushings (7, 8, 9), and at least one of the joined jaws (6a, 6b, 6c, 6d). The distance from the rotational axis to the axis of the cylindrical surface of the sleeve of the crank (7, 9) is greater than the minimum radius adjacent to the crank sleeve (7, 9) of the cylindrical surfaces of the crank journal (3, 10) and the root bushings (8), connected with it. The end face main journals (3, 10), the root bushings and connecting rod (7, 8, 9) in direct contact with their end faces with projections of the cheeks (6a, 6b, 6c, 6d) having a bore. Root and connecting rod bushing (7, 8, 9) with jaws (6a, 6b, 6c, 6d) are connected tetrahedral wedges (11, 12, 13), providing a power connection, while self-promotion is prevented by the wedge lock nuts with locking washers.

EFFECT: use in the construction of collapsible crankshaft ICE V power connections indigenous neck, a native bush and connecting rod bushings with cheeks preserves for a long time reliable operation, as well as simplification of its design through the use of a minimum number of components simple to manufacture, and also improves its repairability.
