Abstract:
A lubrication retainer and distribution system for a worm gear and the mating worm. Porous pads saturated with lubricating fluid are attached to both sides of the worm gear and located so that they spread slightly and wipe the high ridges of the worm. To equalize the fluid distribution between the pads, at least one through hole is formed in the worm gear between the pads, and the hole's size is selected so that capillary action transfers the fluid between the pads as required. Also, to retain the lubricating fluid on the worm, "O" rings are fitted tightly upon the worm shaft just beyond the spiral thread of the worm to act as barriers to prevent fluid from escaping from the system along the worm shaft.
