20080202816 | Torque Converter for Use When Drilling with a Rotating Drill Bit - A torque converter for use in drilling with a rotating drill bit, the purpose of the torque converter being to absorb impacts and bring about an axial movement of the drill bit when the torque exceeds a predetermined value. For this purpose the torque converter is composed of two cylindrical string parts connected through the bearing elements. The string parts are connected to each other through helical elements in such a way that relative rotation of the two cylindrical string parts brings about axial movement, which unloads the drill bit. | 08-28-2008 |
