Abstract: The present invention relates to a chain drive, in particular camshaft/camshaft drive for an automotive engine, the chain drive comprising at least two chain gears and a drive chain. Such a chain drive shall be made more compact without excessively great losses in its low-noise characteristics. To this end at least two chain gears are arranged in laterally offset relationship with one another in axial direction. The drive chain is a multiple-track chain. Each of the offset chain gears has assigned thereto a separate track of the multiple-track chain due to the lateral offset. The tip diameters of the offset chain gears are overlapping.
