ABSTRACT:
A continuously lubricated gear type coupling for connecting a pair of substantially co-axially aligned rotatable shafts comprising: a hub having outwardly extending gear teeth and secured to an end of one of the shafts by a key for rotation therewith; a sleeve surrounding the hub and having inwardly extending gear teeth in meshing engagement with the outwardly extending gear teeth and connected to the other shaft for rotation therewith; a plurality of inlet ports for continuously supplying a lubricant to the inwardly and outwardly meshing gear teeth; a plurality of outlet ports for removal of the lubricant from the coupling after the lubricant has lubricated the inwardly and outwardly extending gear teeth; and an annular impeller surrounding the one shaft and secured to the hub to direct the flow of air or corrosive gases away from the key and keyways of the coupling upon rotation thereof thereby preventing the air or corrosive gases from entering the coupling through the keyway and causing corrosion thereof. The coupling preferably includes a sealing mechanism connected to the end of the one shaft and in sealing engagement with the hub to further insure that air or corrosive gases do not enter the interior of the coupling through the space occupied by the key.
