STUDIES OF BASIC BEARING DESIGNS FOR AN ADVANCED GYRO TEST TURNTABLE.
Abstract
This report presents a simplified approach to the design of externally pressurized, orifice-restricted fluid bearings, with special emphasis on a configuration suitable for the turntable design of Bausch and Lomb Incorporated. Basic flow relationships that enable the solution by digital computer of flow, film thickness, and stiffness of bearings under all practical operating conditions are studied. Three types of bearings are considered: a pair of opposing-thrust air bearings, an eight-pad oil journal bearing, and an eight-pad air journal bearing. In addition to solving for flow, film thickness and stiffness, a detailed analysis of the load capabilities of the oil journal bearing is carried out, as well as an optimization of the bearing design. The solution of a typical design problem using the methods developed is discussed, together with the new techniques required for a thorough bearing analysis. (Author)
