ABSTRACT:
A sheet metal enclosure surrounds all exposed sides of a floor mounted gear drive housing. An electric fan is mounted in an inlet duct at one end of the enclosure and an opposite end of the enclosure has an outlet duct which has an opening to the bottom. Cooling air is drawn into the enclosure through the fan and exits through the opening. The air encounters the normal protruberances and discontinuities in the surface of the gear housing and baffles mounted interior of the enclosure so that the air flow through the enclosure is turbulent. A part of the air flow is directed beneath the gear housing through a channel formed between spaced lateral feet of the housing.
