Filed:

Sep 25, 1987

Appl. No.:

7/100895

Inventors:

Richard W. Holzman - Waukesha WI

Assignee:

The Falk Company - Milwaukee WI

International Classification:

F01M 500

US Classification:

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.

Abstract:

A gear drive has an enclosed housing that acts as a lubricant reservoir. Hollow, finned heat exchanger tubes are mounted in the housing at a level where they are submerged beneath the surface of the pool of lubricant in the housing. The tubes extend outward of the housing and connections are made external of the housing between the tubes and a source of a cooling liquid, such as water, and a drain.
