<p>COOLING SYSTEM FOR GEAR REDUCERS A cooling system for gear reducers having a housing with a lubricant therein, in which a motor for the pump and heat exchanger are mounted on a base structure to form a unitary assembly which can be fully assembled in the manufacturing plant and delivered to and installed at the site of the gear reducer. The temperature of the lubricant in the line from the gear reducer to the pump is sensed by a temperature responsive device and a control valve in the coolant line is regulated thereby for producing an intermittent flow to control the efficiency of the heat exchanger and thereby regulate the temperature of the lubricant in a predetermined range. A second temperature responsive device may be utilized to sense the temperature of the lubricant in the hot lubricant line and to shut down the equipment in the event the temperature of the lubricant, and consequently the temperature of the gear reducer, exceeds a predetermined value. A by-pass line having a relief value may be included between the hot lubricant line and the return line to by-pass the lubricant around the heat exchanger in the event the flow through the heat exchanger becomes restricted and the pressure in the hot lubricant tends to become excessively high. 1.</p> |
