Patent ID: 7682084

Claim:
A screw compressor comprising: a casing; a pair of female and male screw rotors meshed with each other and housed within said casing; radial bearings mounted in sliding contact with rotor shafts of said pair of female and male screw rotors to undergo radial forces transmitted thereto from said rotor shafts; and thrust bearings disposed on both sides of a disc-like thrust member, said disc-like thrust member being fitted on one of the rotor shafts of each of said pair of female and male screw rotors, to undergo a thrust force transmitted from the associated screw rotor to said thrust member, wherein at least one of said radial bearings and said thrust bearings each comprise: a backing strip; a slide member comprising a resin layer and bonded to said backing strip, said bearing undergoing a force through said resin layer; a temperature measuring metallic member, said temperature measuring metallic member being fitted in a fitting hole which is formed from said resin layer side and has a depth exceeding the thickness of the resin layer; and a temperature sensor for measuring a temperature corresponding to the temperature of said temperature measuring metallic member, said temperature sensor being fitted in a hole formed in said backing strip.
