摘要： A screw compressor comprises a casing and a pair of male and female rotors respectively having herical teeth and grooves formed in their outer peripheries. The rotors are arranged within the casing in meshing relation to each other through the teeth and grooves. Each rotor is rotatably supported by a pair of first and second radial plain bearings and a thrust plain bearing which is arranged at an end of the rotor shaft and adjacent the second radial plain bearing. Each of the thrust plain bearings is of dynamic-pressure type in which with rotation of a corresponding one of the shafts of the respective rotors, pressure is applied to lubricant by sliding movement of the thrust plain bearing to produce an anti-thrust force. The lubricant for each of the second radial plain bearings and for a corresponding one of the thrust plain bearings is fed to a space between the second radial plain bearing and the thrust plain bearing, and is distributed to the second radial plain bearing more in amount than that fed to the thrust bearing due to a difference between flow resistance with which the lubricant passes through the second radial plain bearing and flow resistance with which the lubricant passes through the thrust plain bearing.

摘要： A multi-lobe foil gas bearing which can accomplish high accuracy rotation by means of a stable fluid lubricating film without being affected by a rotational position or a driving system of a journal at the time of starting is provided. Since two foils are arranged with different phases in a circumferential direction so that each vertex part of one of the two foils is positioned in an arc surface part of the other foil in a plan view seen from a shaft end of the journal, a part having low rigidity and a part having high rigidity of the multi-lobe foil gas bearing compensate each other to eliminate a local part having low bearing rigidity. As a result, it is possible to eliminate a phenomenon such as moving or leaning of the journal at the time of starting, while the fluid lubricating film can exist over the entire circumferential surface of the journal to keep stable high accuracy rotation of the journal.
