Analysis of Defective Hydrostatic Radial Bearings for Five Megajoule Homopolar Generator
MetadataShow full item record
Hydrostatic bearings were designed for a five megajoule homopolar generator since they offered the advantages of low shaft friction, high load capacity and high stiffness independent of shaft speed. The original bearings were satisfactory except for electrical pitting. A redesign using a high pressure laminated (G-9) fiberglass cloth reinforced melamine-formaldehyde resin composite resulted in a defective design. Design parameters are given with a complete analysis showing where the design was defective along with a satisfactory solution used in a subsequent redesign.
