A Variational Method for Solving the Isthermal Problem of the Hydrodynamic Theory of Lubrication for a Thrust Bearing Having an Undeformed Pad,

Abstract

The article deals with the problem of the hydrodynamic theory of lubrication of the pad of a thrust bearing with a rectangular supporting surface. Integration of the Reynolds equation was performed in an approximate manner by the Kantorovich variational method. The solution of the problem was determined in the second approximation. Characteristic curves were constructed for the parameters which determine the carrying capacity, the force of friction, the point of approach of the resultant forces of pressure, the consumption and temperature rise of the lubricant. An example of calculation of the thrust bearing is given.
