Liquid Bearing Gyro Investigation.

Abstract

The objective of this program was to fabricate and test two liquid hydrodynamic bearings to be subsequently incorporated into a liquid bearing gyro. The liquid bearing design consists of a spiral grooved journal bearing with two 'in-pumping' thrust plates. The low viscosity hydrocarbon bearing fluid is captured in the bearing gap by preloaded mercury ring seals at the ends of the journal shafts. The seal capability has been shown to be greater than one atmosphere under static conditions and greater than two atmospheres under dynamic, running conditions. Instrumented tests show the inherently, noise free operation of the liquid bearing.
