Abstract
A fluid dampened support for a rolling element bearing such as a ball bearing, needle bearing, roller bearing and the like. The fluid dampened support includes a network of closely spaced beams which support the outer race of the roller bearing for movement in any direction. A liquid is provided in the spaces between the beams to dampen such movement. The structure and space between the beams is designed so as to provide virtually any reasonable damping characteristics. By providing such damping characteristics, the bearings are able to limit or damp out the vibrations occurring when the supported member passes through natural frequencies before reaching operating speed. This allows use of the rolling element bearing in high speed equipment such as compressors and turbines.
