Abstract
Flooded oil lubrication systems are commonly utilized for many manufacturing processes. However, there is an increasing concern with the flooded lubrication systems due to their biological and environmental impact as well as their maintenance and disposal cost. Polymer-based material, a sponge-like solid lubricant allowing the oil to weep out while in use, provides a promising alternative environmentally benign lubrication solution to satisfy the lubrication requirements for some manufacturing processes. In addition, it can minimize contamination of the coolant system, reduce waste processing and disposal costs, and alleviate the in-plant safety hazard from oil leakage on floor surfaces.
The goal of this study is to develop and improve the current lubrication system by applying a polymer-based near-dry lubrication system in order to replace the oil-flooded transfer line lubrication systems currently in production use. Using a laboratory reciprocating bench test based on the design of experiments, this study characterized the tribological performance of the polymer-based lubrication system under a variety of operating conditions, identified the main factor that impacts the tribological performance of the polymer-based lubrication system, and developed a model to predict the wear loss of the polymer-based lubricant plate. These results provide the guidelines for possible applications of the polymer-based lubrication system used in the manufacturing process.
