<p>A screw conveyor (100) is formed by connecting conveyor units (2), which house screws (3), in the direction of the rotating shafts (3a) of the screws (3). First and second fluid bearing sections (10, 20) are disposed between the connected ends of the conveyor units (2). The fluid bearing sections (10, 20) are provided with rotating rings (30) and stationary members which are subjected to loads from the rotating rings (30). The fluid bearing section (10) rotatably supports, at the pressure generating sections thereof, the rotating ring (30) in the radial direction and the thrust direction without contact. The fluid bearing section (20) rotatably supports, at the pressure generating sections thereof, the rotating ring (30) in the radial direction without contact. A bearing operating medium is supplied to each of the pressure generating sections after the flow rate thereof is controlled by a flow rate control valve (5c) of a control unit (5b) for controlling the flow rate of the bearing operating medium.</p> |
