New oils for oil mist lubrication to reduce fine oil droplets in stray mist
- Texas A and M Univ., College Station, TX (United States). Dept. of Mechanical Engineering
In the widely used open loop oil mist lubrication system, the unused oil mist, called stray mist, is vented out into the atmosphere. The stray mist contains very little oil and applications can easily meet the OSHA requirement of maximum allowable 5 mg of oil per m{sup 3} of air. However, it has been found that for some widely used oils the stray mist contains large numbers of sub-micrometer oil particles. These particles are too small to lubricate bearings and are potentially harmful to the human respiratory system. Several new lubricating oils have been developed and tested to reduce fine oil droplets in the stray mist. The best blend of oil was able to reduce the sub-micrometer particles in the stray mist by about 75% as compared to the version of this oil currently being used. This has been accomplished without any significant change in the parameters influencing the lubrication of bearings.
