Abstract
The considering problem in the article connects with solution methods of the specific questions in gas-dynamic lubrication theory. The comparative analysis of analytical and numerical methods for the calculating gas-dynamic bearing characteristics is provided. The main applying aspects of them for the solving of specific gas lubrication theory points are presented. This research is carried out for the investigated gap bearing geometry for the designed ball gyroscope construction. The main mathematical equation and results of developed numerical simulation for the pressure distribution determination are shown.
Highlights
During the gyroscopic technology development, rotor bearing construction has remained one of the main gyroscopy problems
Gas lubrication application for the gyroscopic devices was determined by the tendency of increasing the gyroscope accuracy, rigidity and operating life
The ball gyroscope construction is different from others in quite high resistance to overloads and impacts of external dynamic effects
Summary
During the gyroscopic technology development, rotor bearing construction has remained one of the main gyroscopy problems. The main type of gas bearings as a part of such gyroscopic devices are gas-dynamic bearings (GDB) This is due to a strong requirement for gyroscope weight and size parameters; gas-dynamic bearings do not require additional excess pressure sources such as gas bearings with an external pressurization. The final selection of the rotor bearing type and parameters depends on the field of application, design features, and developing purposes. These aspects of research work were considered in the previous article [2]. It is expected that basing on such type of gyroscope with the hemispherical configuration of GDB will allow creating a reliable and sufficiently accurate inertial navigation system for the solution of relevant problems of metrological drilling process maintaining
