Test Results Report and Design Technology Development Report - HLH/ATC High-Speed Tapered Roller Bearing Development Program.

摘要

The high-speed and load capability of tapered roller bearings has been demonstrated by several research and development programs conducted jointly by the Boeing Vertol Company and the Timken Company. Tests were conducted on a 3.5-inch bore (6500series) tapered roller bearing operating at 16,000rpm (20,000 fpm) and supporting a thrust load of 5500pounds and a radial load of 7500pounds. Although the tests were successful and demonstrated the high-speed capability of tapered roller bearings,additional experimental testing appeared necessary to evaluate the tapered roller bearings selected for the HLM/ATC drive system.
