Abstract: A parched subregime of elastohydrodynamic lubrication is proposed, lying between starved and mixed. Parched EHL is necessary to describe instrument ball bearing behavior, for example: long term ...

Abstract: Load carrying capacity between the balls in a retainerless bearing, theoretically zero, is shown experimentally to be large enough to allow for full complement operation.

Abstract: A sphere rolling between a stationary and a spinning plane traces out a spiral path, even under quasistatic conditions. Published theory suggests that radial creep due to pivot produces the ...

Abstract: We made an experimental investigation of the motions of the retainer in an instrument ball bearing during stable operation and during squeal. Radial motions of the retainer were measured with ...

Abstract: The NASA Ball on Plate Tribometer was built for the investigation of boundary lubricated rolling. Its contact conditions are easily calculated, and can be adjusted to match a range of real ...

Abstract: This 1961–1962 lubrication digest reviews developments in fluid-film and rolling-element bearings, lubrication for bearings, gears, and automobiles; and covers basic work done in the general areas ...
