PURPOSE:To widely simplify construction, by applying bearing construction, integrally formd with a thrust bearing, bearing metal, thrust receiver, suction port, Oldham's guide groove, etc., and a suction line integrally formed with the bearing device. CONSTITUTION:A thrust bearing 35, bearing metal 37, thrust receiver 38, Oldham's guide groove 43, suction port 44, etc. are fitted to an integrally formed bearing 7, then an Oldham's coupling 34 is inserted into the bearing 7. A rocking scroll 2 is fitted to a crankshaft 6 from the above of the Oldham's coupling 34, and a fixed scroll 1 is fixed from the below to the bearing 7 by bolts 78. Then a balance 10 is mounted from the lower part of the crankshaft 6, and a spacer 13 is inserted to integrally fix the balance 10, spacer 13 and electric motor rotor 8 to the crankshaft 6 by a rotor stopper nut 17. Such bearing construction and a suction line integrally formed with said bearing are applied, then the construction can be widely simplified. |
