Abstract: It has been shown that half-frequency whirl is influenced by orifice location, number of grooves, groove location, and so on. This paper presents test results which show the effect of geometry ...

Abstract: Performance of advanced air-breathing propulsion systems can be significantly improved through the utilization of effective sealing devices. One of the areas in which immediate benefits are ...

Abstract: The design and experimental evaluation of a series-hybrid thrust bearing, consisting of a 150-mm ball bearing and a centrifugally actuated, conical, fluid-film bearing, is presented. Tests were ...

Abstract: The classical differential equations of motion of the ball mass center in an angular contact thrust loaded ball bearing are integrated with prescribed initial conditions in order to simulate ...
