内容記述 | Both the experiment by Kingsbury on a full journal bearing using air as a lubricant and its mathematical analysis by Harrison have historical values in the theory of lubrication. Harrison, however, could not integrate the fundamental differential equation in any form convenient for calculation, and he only succeeded in the numerical integration by using the data of Kingsbury. The results of his calculation coincided well with those of Kingsbury's experiment, but his method was very troublesome, and he failed in knowing the whole characteristics of the air-lubricated journal bearing. The authors succeeded in solving the problem mathematically with good approximation, and the pressure distribution in the bearing, the most important characteristic thereof, was found to be given by the following formulas, [numerical formula] where p is the pressuse of air in the bearing clearance, p_0 the pressure which determines the total mass of air in it, η the viscosity of air, r the radius of journal, δ the radial clearance of bearing, U the circumferencial velocity of journal, c the eccentricity (and s^2 = 1 - c^2), θ the angle measured in the direction of rotation from the point of maximum clearance, and ν a parameter. Based on these formulas, the authors deduced the whole characteristics of air bearing, such as friction coefficient, eccentricity and others, as functions of running conditions. Interesting features peculiar to bearings lubricated by compressible fluid were discussed in comparing with those for which the lubricant was assumed to be incompressible. | |||||
