ABSTRACT:
The specification discloses a bearing lubricating system including a shaft having two inner raceways formed therearound and a concentric bore formed in the shaft. Passageways communicate between the bore and the inboard portion of the inner raceways. Balls are provided having radii slightly less than the arc radii of the raceways. The bearing structure is completed by an outer ring having two outer raceways formed therein. The outer raceways in the outer ring are separated more than the separation between the inner raceways in the shaft such that the balls contact the inner and outer raceways at an angle to a plane perpendicular to the axis of the bearings. As a result, the balls contact the inner raceways on the outboard portion of the raceways to prevent the balls from contacting the opening of the passageways into the inner raceways. The bore formed in the shaft is threaded along its entire length and is loaded with a suitable lubricant. A set screw is threadedly engaged in the threaded bore to form a reservoir of lubricant communicating with the passageways leading to the inner raceways. By selectively advancing the set screw in the threaded bore, lubricant is forced through the passageways and expelled onto the inner raceways where the lubricant is applied to and picked up by the balls as they move in the raceways.
