... of analyzing the contact at discrete positions assuming time-invariant parameters. The normal tooth force along the line of action is predicted by using a gear load distribution formulation and the contact radii and tangential surface velocities are computed from the kinematics and geometry of involute...

Wray; Zhilin Dong The objectives of this study are to experimentally investigate the performance characteristics of similar slipper bearings using different socket geometries. In this study, the lubrication equations for the bearing are derived based upon an assumption...
