Abstract: A mechanical drive system includes a mechanical drive component, an enclosure, and a centrifugal fan. The mechanical drive component has a housing and a rotatable shaft supported within the housing. The enclosure is disposed on the housing and a wall of the housing has an output opening therein through which the rotatable shaft of the mechanical drive component extends and another of wall has an intake opening therein. Surfaces of the housing and the walls of the enclosure define an air passage channel extending from the intake opening to the output opening. The centrifugal fan is aligned and in fluid communication with the output opening of the enclosure. The impeller is operatively connected to the rotatable shaft.
