ABSTRACT:
Cooling apparatus is disclosed for drives of the type having a housing containing a sump for a fluid which is heated by the generation of heat energy during operation of the drive. The heat energy is generated by relatively moving torque transmitting members, such as clutch and brake units, connected between the drive input and output shafts. A centrifugal pump located within the housing below the level of the fluid is driven by the input shaft and circulates fluid to a heat exchanger disposed about the outside surface of the housing. The cooled fluid is returned to the fluid sump and a brake reservoir which assures an ample supply of fluid to the brake at a relatively low pressure. A fan carried by the input shaft blows ambient air over the heat exchanger and exterior surface of the housing to enhance the level of heat dissipation.
