Abstract

See full text

A bearing device with first and second bearing surfaces facing each other and which are moveable relative to one another. The first and second bearing surfaces are separated by a bearing gap filled with a lubricant. The lubricant comprises a carrier fluid and particles which respond to magnetic or electric fields. The particles are suspended in the carrier fluid in the absence of magnetic or electric fields. One or more magnetic or electric field generators are embedded in the first or second bearing surface to generate a localized magnetic or electric field which locally removes the particles from suspension by exerting a field force on the particles. This forms a local flow obstruction on at least one of the bearing surfaces in the form of an agglomerate of previously suspended particles. The local flow obstruction locally obstructs a flow of the lubricant.
