Abstract
A compensating drive for driving a compensating shaft of an internal combustion engine, comprising a toothed belt or a chain, which connects a crankshaft driven wheel of the internal combustion engine to a drive wheel on the compensating shaft or shafts, in which case the crankshaft driven wheel () and/or the drive wheel or wheels () of the compensating shafts () are shaped to be non-circular in such a way that they transmit to the drive a variability, which at least partially compensates the vibrations produced during the rotation of the crankshaft ().
