ABSTRACT:
A drilling bit for drilling earthen material such as an oil well rotary cone drilling bit, which includes means for preventing foreign particles such as sand, rock cuttings, etc., from reaching the rotational bearings of the bit cones. This end result is principally achieved by means of a centrifugal slinger disc or wall which is positioned in external concentricity with the drill bit cone bearing, and operates to drive granular particles away from the bearings, thereby preventing such particles from reaching these bearing surfaces. The granular particles are driven by the slinger action through a series of apertures forming a channel running out to a peripheral region of the bit cones. A channel continuation is also provided for lubricating fluid, which many comprise ambient water or oil placed in chambers surrounding the bearings, this channel providing access for such lubricating fluid inwardly to the bit cone bearings. A ring member carrying a plurality of curved vanes, this ring member being externally concentric with the supporting shaft of the cone and located near the outer periphery of the bit cone, may also be employed to prevent larger foreign particles, such as cuttings, from entering into the region of said slinger.
