Abstract
The dynamic equations of motion of ball-bearing separators were solved using certain simplifications to make computer analysis feasible from a cost point of view. A typical turbine engine bearing, employing solid lubrication, was used for a trade-off and optimization study of ball-separator design. The effects of varying geometric parameters of the separator were studied, along with different friction and traction coefficients and operating speeds of the bearing. The computer analysis indicated that the ball-pocket collision forces are significantly affected by the geometry of the ball separator (particularly the working clearances), and are also sensitive to the traction and friction coefficients of the materials and lubricant system. Presented at the 39th Annual Meeting in Chicago, Illinois, May 7–10, 1984
