  • Cone locking system for a rotary rock bit
    Patent number: 4098150
    Abstract: The rolling cone cutter of a rotary rock bit is held in place on the bearing pin without the use of the conventional ball bearings. The bit includes a body with a bearing pin extending from the body. A rolling cutter is adapted to be rotatably mounted on the bearing pin. A locking means locks the cutter on the bearing pin. The locking means includes a groove in either the roller cutter or the bearing pin. A flange-type retaining element positioned on the opposite member, either the rolling cutter or bearing pin, projects into the groove and retains the rolling cutter on the bearing pin.
