る部品が変形する問題があった。Conventionally, in hermetic electric compressors, for example,
As shown in Publication No. 3-100111 and Japanese Utility Model Publication No. 52-24805, etc., the oil plug is attached directly to the upper end of the end ring of the motor rotor by caulking, etc., before fixing it to the rotating shaft. It was configured. Therefore, when the rotor is shrink-fitted onto the rotating shaft, the shaft hole of the rotor is covered with the oil separation blocking plate, so the shaft hole cannot be crossed. The problem is that it becomes difficult to align the hole and the rotating shaft, and the shrink fit workability is poor. In addition, in order to improve these problems, it is possible to install all the oil separation blocking plates after fixing the rotor to the rotating shaft. There is a problem in that the rotating shaft or the parts supporting the rotating shaft are deformed because the rotating shaft is subjected to the strong stress of the rotating shaft.
