Summary:A crank drive for a reciprocating-piston engine includes a crankshaft which has at least one crank pin. At least one eccentric is rotatably arranged on the crank pin via which at least one connecting rod is to be rotatably mounted on the crank pin. A piston can be arranged so as to move in a translatory fashion in a cylinder having a variable compression ratio of the reciprocating-piston engine and can be coupled in an articulated fashion via the connecting rod to the crankshaft. At least one actuator shaft is arranged coaxially with respect to the crankshaft, by which actuator shaft the eccentric can be rotated relative to the crank pin by driving the actuator shaft. As a result, the compression ratio of the cylinder can be adjusted. An actuator element, by which the actuator shaft can be driven, is arranged at one end of the crankshaft and adjoins the actuator shaft in the axial direction of the crankshaft.
