Zusammenfassung:The invention relates to a crankshaft ( 1 ) for a reciprocating internal combustion engine, in which the connecting rods are mounted, with an eccentric sleeve ( 4 ) connected in between, on the crankshaft journal ( 3 ) of a crankshaft ( 1 ). A rotation of the eccentric sleeve ( 4 ) with respect to the crankshaft journal ( 3 ) therefore leads to a change in the effective length of the connecting rod. The rotation of the sleeve ( 4 ) is brought about via an electric or hydraulic motor ( 7 ) which drives a worm ( 6 ) which engages in an outer toothing ( 5 ) of the sleeve ( 4 ). By means of the active drive, rotation of the sleeve ( 4 ) is ensured even if the auto-rotation is impaired due to the occurrence of wear. Furthermore, a self-locking design of the worm gear has the effect of the sleeve ( 4 ) being retained in its set position when the drive ( 7 ) is switched off.
