AN INVESTIGATION OF SPIN AXIS INSTRUMENT BEARINGS.

Abstract

The research is concerned with problems arising in the performance of spin axis instrument bearings when used in high angular momentum gyroscope wheels. The main research efforts have been in bearing material develop ments, from which improved materials and treatments have resulted; however, the prevelence of failures through polymerization of the lubricant has focused the research on surface cleanliness and lubrication. In this respect, it is hypothesized that lubricant polymerization may be catylized by surface-adhered particles which remain from the final manufacturing operations. These particles cause freshly cut metal surfaces at the bearing interface which in turn emit exo-electrons which may be instrumental in the polymerization of the lubricant. Preliminary data on the polymerization of lubricants indicate that the rate of polymer formation is strongly influenced by the cleanliness of the bearing surfaces.
