Abstract:

Spherical roller bearings have typically been used in applications with speeds limited to about 5000 r.p.m. and loads limited for operation at less than about 0.25 million DN. However, spherical roller bearings are now being designed for high load and high speed applications including aerospace applications. A computer program, SASHBEAN, has been developed to provide an analytical tool to design, analyze, and predict the performance of high speed, single row, angular contact including zero contact angle, spherical roller bearings. The material presented in this document is the mathematical formulation and analytical methods used to develop computer program SASHBEAN. For a given set of operating conditions, the program calculates the bearings ring deflections axial and radial, roller deflections, contact areas and stresses, depth and magnitude of maximum shear stresses, axial thrust, rolling element and cage rotational speeds, lubrication parameters, fatigue lives, and rates of heat generation. Centrifugal forces and gyroscopic moments are fully considered. The program is also capable of performing steady-state and time- transient thermal analyses of the bearing system.
