ABSTRACT:
The invention comprises a novel method for lubricating and cooling mechanical seals, particularly those seals used in a vertical drill box system. Specifically, the invention utilizes the driving force of the rotating gears in the gear box to convey fluid to an otherwise inaccessible upper seal face. Cooling and lubricating the seal in this manner insures that the various rubber portions of the seal are not degraded by excessive heat. The invention can be utilized in any application requiring sealing of gearing mechanisms from environments containing large amounts of dust or other debris. A preferred application is in mining equipment.
