Abstract
An integral fan and airflow guide including a hub having a frusto-conical outer surface, and a plurality of fan blades circumferentially spaced apart about the hub and radiating outwardly from the hub. The frusto-conical outer surface having a plurality of circumferentially spaced apart slots that separate inclined segments of the outer surface to define respective airflow guide surfaces. The plurality of fan blades are integral with the respective airflow guide surfaces. The inclined airflow guide surfaces cooperate with the fan blades to direct impelled air axially and radially outwardly for improving the cooling of a machine component, such as a hydrostatic transmission, that is obstructed from airflow by a pulley or other obstacle.
