A Graphical Study of Journal Lubrication

H. A. S. Howarth


This paper visualizes the characteristics of the oil film and the pressures within it for a journal completely surrounded by its bearing. The influences of clearance and viscosity upon the journal friction are quantitatively shown by means of a chart that can readily be used for designing bearings. Several interesting examples are solved by means of this chart.

A few of the characteristics of the journal partially surrounded by the bearing are also shown by curves. The study of partial bearings is not yet completed.
