  • Patent number: 9644629
    Abstract: A scroll compressor having a bearing is provided. The scroll compressor includes: a casing; a main frame fixed to the casing and having a shaft insertion hole formed therein; a fixed scroll fixed to the casing and disposed above the main frame; an orbiting scroll forming a compression chamber together with the fixed scroll and having a boss portion formed on a lower surface thereof; a rotational shaft having an end portion insertedly fixed in the boss portion in a state in which the rotational shaft is insertedly positioned in the shaft insertion hole; and a lubricating layer made of a PEEK material and formed in the shaft insertion hole or the boss portion, wherein the lubricating layer is formed by applying a liquid material to the shaft insertion hole or the boss portion.

  • Patent number: 9217433
    Abstract: A synthetic resin bearing and a scroll compressor using the same are provided. In the synthetic resin bearing as a journal bearing fixed to an orbiting scroll or a main frame and relatively rotated with respect to a rotational shaft in a scroll compressor, the journal bearing is made of a PEEK material, and a thickness t of the journal bearing is smaller than a thickness t1 with which a temperature in a contact surface thereof with the rotational shaft during an operation of the scroll compressor corresponds to a glass transition temperature.

  • Publication number: 20130078130
    Abstract: The present disclosure relates to a scroll compressor. According to the present disclosure, an oldham ring for preventing the rotation movement of a orbiting scroll may be fabricated by sintering metal powder to have a yield stress above 300 MPa, and thus even when a gas force is eccentrically generated it may be possible to prevent the oldham ring supporting the circular movement of the orbiting scroll from being damaged due to this, thereby enhancing the compressor performance.
