Методи підвищення характеристик радіальних газових підвісів з поздовжніми канавками

Abstract

The article deals with a radial gas bearing with longitudinal grooves of different depths and the effect of grooves, with different incline profile in the direction of gas flow, on the characteristics (radial rigidity, lifting force and gas flow) of the bearing. It turned out that from the proposed forms of the longitudinal grooves of the radial gas bearing, in comparison with the bearing with grooves of constant depth with optimal design parameters, there are tilting profiles of grooves and steps that increase the dimensionless radial rigidity (by 54% and 20%, respectively). The method for calculating the characteristics of radial gas bearings with longitudinal grooves using the methods of splines proposed. The flow rate of gas through the working clearances of bearings is practically independent of the profile of the grooves.
