    Rotor assembly of motor for hermetic rotary compressor
    The present invention relates to a hermetic rotary compressor, and more particularly to a rotor constituting the motor of the compressor, and in particular, by fastening the respective components in a screw-fastening manner, the fastening work is convenient and the fastening failure is reduced. The rotor assembly of the motor for a hermetic rotary compressor can be easily disassembled and repaired without damage.
    A general hermetic rotary compressor is composed of a motor 1 and a compression pump 2 for compressing refrigerant sucked while operating in conjunction with rotation of the motor 1, as shown in FIG. 1) and the compression pump (2) is fixed in the cylindrical sealed container (3).
    A discharge pipe 4 is installed at an upper side of the sealed container 3, an oil pan 5 for storing oil is installed at a lower side thereof, and a side for guiding refrigerant into a cylinder of the compression pump 2. The accumulator 6 is installed.
    The motor 1 is composed of a stator assembly 10 and a rotor assembly 20, the stator assembly 10 is fixed to the inner surface of the hermetic container 3, the rotor assembly ( 20 is provided to maintain an appropriate gap on the central axis of the stator assembly 10.
    When a current is applied to the stator assembly 10, a rotating magnetic field is generated, the permanent magnet rotor assembly 20 is induced to rotate, and the compression of the compression pump 2 is performed by the rotational force of the motor 1. The refrigerant sucked into the cylinder is compressed to high temperature and high pressure and discharged through the discharge pipe.
    As shown in FIG. 2, the rotor assembly 20 includes a rotor 21 having a shaft hole 21a at a central portion thereof, and upper and lower end plates 22 attached to upper and lower surfaces of the rotor 21. 22 '), a pair of semi-circular balance weights 23 and 23' which are provided rotationally symmetrically on the upper and lower parts of the rotor 21, and the upper and lower end plates 22 and 22 'and the balance weight. It consists of several rivet pins 24 which fix the 23 and 23 'with respect to the rotor 21. As shown in FIG.
    The rivet-pin 24 passes through the rivet holes of the balance weights 23 and 23 ′, the rivet holes of the upper and lower end plates 22 and 22 ′, and the rivet holes of the rotor 21. It is inserted so as to protrude downward from, and is cocked by a jig as shown in Figure 3 to secure each component.
    The jig includes a top jig 25 for closely contacting the upper portion of the rivet-pin 24 to the balance weights 23 and 23 'and an end portion of the rivet-pin 24 to the end plates 22 and 22'. It consists of an expansion jig 26 which expands to be fixed.
    In the conventional rotor assembly as described above, each component, for example, upper and lower end plates 22 and 22 'and upper and lower balance weights 23 and 23' is set on the rotor 21. While pressing the upper part of the rivet-pin 24 with the top jig 25, the lower part is extended with the expansion jig 26 to fix and assemble the parts.
    However, the rotor assembly of the general hermetic rotary compressor motor as described above, by fastening the respective components by rivet-pin, not only the fastening operation but also a problem that the fastening failure occurs. In other words, if the pressing force of the top jig is too large, deformation occurs in the rotor, and if the pressing force is too small, the expansion jig does not fully expand and a fastening failure occurs in which the component flows.
    In addition, the rotor assembly using the rivet-pin cannot reuse the rivet-pin because the end of the rivet-pin must be reworked when the rotor assembly needs to be disassembled for repair. There was a lot of difficulty in maintaining, such as damage.
    The present invention has been made in view of the above, it is not only easy to fasten each part when assembling the rotor assembly, but also can reduce the fastening failure, can be disassembled and dismantled without damaging other parts It is an object to provide a rotor assembly of a motor for a hermetic rotary compressor.
