Abstract:

The object of this program was to investigate the feasibility of tapered roller bearings to operate under future gas turbine engine requirements of speed and load. A speed of 3,500,000 DN 107.95 mm bore X 32,422 rpm and 5000 pounds thrust load were set as goals. The analytical work involved defining various bearing parameters that would influence the design and performance under high speed operation. A total of thirty bearings were designed and fabricated for the testing portion of the program.
