    2012-1-20 · Ball bearings play an important role in various rotating machineries, but the complicated kinematic and tribological features of ball bearings make many aspects of their operating behaviors still inconclusive. Most theoretical analyses of ball bearings up to date are based on either the hypothesis of race control or other empirical models to determine the ball motion of ball bearings…

    2016-5-27 · The development of special grease makes it possible for angular contact ball bearings to operate at high speed and temperature; however, as an important performance parameter, friction torque of bearings lubricated with grease is much greater than that of bearings lubricated with oil-air, and heat generation due to frictional loss is also greater, so it is necessary to predict the friction …

Thrust roller bearings transmit load from one raceway to the other to accommodate radial loads. Bearings like these also have a self-aligning capability that makes them immune to shaft deflection and alignment errors.

    The 'perfect' ball bearings would be elliptical, the 'uniform' alloy would have density gradations, and the 'pure' biological extract would be contaminated with impurities. There are two ways to look at how these residual tidal forces occur. One picture uses the concept of orbital motion and the other uses the concept of gravity gradients.
