Abstract
Lubricating nutating single cone drill bit (10, 100) includes bit shank (12, 112) with axially skewed journal (18, 118) rotatably retaining cutter body (22, 122). Bearings (26, 28, 30, 32; 126, 128, 130, 132) can enable rotation of cutter body (22, 122). Lubricant can be dispensed to a gap between journal (18, 118) and cutter body (22, 122) from lubricant chamber (76; 176, 179) having plunger (80; 180, 183), the gap bounded by first (66, 166) and second (68, 168) radial dynamic seals. Fluid passage (90, 190) extending through bit (10, 100) can communicate with fluid inlet port (88, 188) on proximal end (16, 116) of bit shank (12, 122). Fluid passage (90, 190) can further communicate with first fluid outlet port (98, 198) on distal end (36, 136) of journal (18, 118) and with second fluid outlet port (94, 194) formed on lateral portion of bit shank (12, 112).
