Definitions

  • Rock drill bits used for drilling to a substantial depth into the earths crust normally consist of a number of cutter cones rotating on a stem.
  • the bearing surfaces between the cones and stem are lubricated by a grease.
  • the grease is sealed into the bit before use and it should provide lubrication for the lifetime of the bit, which may be several hundreds of hours.
  • the bit has to be replaced because of wear of the cutting surfaces but, since retrieving and replacing a bit is a time-consuming operation, it is desirable that the bit should last for the full lifetime of its cutting ability and should not fail prematurely through failure of its lubricating system.
  • the environment within which a rock drill bit operates can be severe. Heavy loads may be imposed on the rotating cutter cones, particularly when drilling through hard rock formations and high temperatures and pressures may exist in the vicinity of the bit. Further the bore of the hole being drilled may be filled with drilling mud containing abrasive particles.
  • a particularly suitable lithium complex soap may be formed from 12-hydroxy stearic acid, dodecanedioic acid, distilled tallow fatty acid and lithium hydroxide monohydrate.
  • compositions of the three greases and their characteristics were as shown in Table 1 below:
  • the EP wear properties were measured using the 4 Ball method (IP Test No 239).
  • the flow properties were measured in a suitable rheometer by applying a force (shear stress) to the greases and measuring the rate of flow (shear rate). The apparent viscosities shear stress were then calculated. shear rate
  • Thermo-mechanical analysis is a technique for comparing changes in consistency of a material over a temperature range.
  • a small probe 5 mm in diameter is loaded (0.3gm) against a small sample of grease in a hollow about 1 to 2 mm deep. Starting at room temperature, the assembly is heated at 10°C/minute up to 260°C. As the grease softens, the probe sinks further into the grease, ie the probe height is reduced. If any significant expansion occurs, the probe height increases. If hardening takes place, the probe height changes only slightly with temperature.
  • a commercial conventional lithium soap grease (C) starts to change at 120°C, expands up to 160°C, and then softens rapidly.
  • the commercial aluminium complex soap grease (A) starts to soften almost immediately and is softer than LXB3 up to 200°C.
  • the commercial calcium complex soap grease (B) shows no change in probe height indicating early and maintained hardening.
  • Commercial drill bit grease D1 shows expansion up to 120°C and then a gradual change consistent with hardening.
  • Commercial drill bit grease D2 starts to soften as soon as 80°C and thereafter increases rapidly in softness.
