Abstract:
The invention relates to a bearing device comprising a first surface and a second surface which are moveable relative to one another, wherein the first and second surfaces are separated by a bearing gap filled with a lubricant, which is a magnetorheological or electrorheological liquid, or a lubricant having a temperature dependent viscosity, or a lubricant having a controllable slip velocity. The bearing device further comprising one or more supply inlets in the first or second surface, and one or more activators embedded in the first surface or second surface and configured to locally increase a viscosity or decrease the slip velocity of the lubricant in at least one obstruction zone, thereby inhibiting a flow of the lubricant in the obstruction zone.
