ABSTRACT:
A drive device (1) for machine auxiliary units (K, L, S/G) for transmitting a machine drive force from a machine (VM) to the machine auxiliary units by a belt. At least one machine auxiliary unit is provided as an electrical machine (S/G) that has either a poly-V-belt pulley to be driven by a poly-V-belt or a toothed belt pulley to be driven by a toothed belt. The belt has a toothed side (R1) and a poly-V side (R2) opposite one another, wherein a machine belt pulley is designed to drive the toothed side of the belt for transmitting the machine drive force, if the electrical machine has a poly-V-belt pulley, or is designed as a poly-V-belt pulley if the electrical machine has a toothed belt pulley.
