Abstract
The paper describes investigations into the performance characteristics of ball-bearings and roller-bearings running under conditions similar to those encountered in gas turbines. The majority of the work was carried out on ball-bearings, suitable for shafts of 2 inches diameter, which were run under various combinations of radial load and thrust load. Modifications were made to diametral clearance and track curvature of the bearings and to the material, design, and dimensions of the cages. The effects of these on bearing performance are given and discussed. Investigations on larger (5-inch bore) bearings indicate additional precautions necessary with this size. Work on roller-bearings was confined to the 2-inch size and the variables investigated included diametral clearance of bearing and end clearance of rollers. An interesting comparison is provided by the performance of a cageless roller-bearing.Keywords
