Temperature reduction using PD additives

摘要

High temperatures have an effect on the lifetime of equipment like bearings, seals or lubricants. Special lubricant additives can help to reduce the temperature of lubricated systems. In addition to lower temperatures, increased energy efficiency effects are often seen in these systems. PD-additives (plastic deformation additives) can lower the temperature in equipment like high loaded gears or roller bearings. The impact of this temperature reduction has often been proven by tests conducted by customers as well as on very special test rigs. This test results are often not comparable with other results. This paper will show the temperature reduction effected by PD additives taking some common test rigs as FZG [1] and FE8 [2] test machine as well some results of customer tests.
