Abstract

The disclosure relates in general to an oil-mist lubrication system, and more particularly to the propagation of a mixture of oil-mist to bearings of a spindle, wheelhead, or the like by means of a blender-distributor unit. A first controlled amount of air from an air supply unit is fed through an oil-mist unit to produce a controlled high density oil mist. A second controlled amount of air from the air supply unit bypasses the oil-mist unit and is fed into an air chamber of a blender distributor unit. The high density oil mist is also fed into an oil-mist chamber of the blender distributor unit. A plurality of blending nozzles in the distributor unit extend from the exit side of the air chamber. A like plurality of tubes extend from the exit side of the oil-mist chamber of the distributor unit, each tube mounted coaxially within a respective nozzle whereby the blending area of the exit end of each tube within the nozzle produces a lower density oil-mist to be carried to the bearings. Depending upon the number of bearings to be lubricated, more or less exiting nozzles from the blender distributor unit can be utilized with the air pressure and high density oil mist being regulated a…
