A compressor according to the present disclosure may include a container; a drive motor provided in the container; a crankshaft coupled to a rotor of the drive motor; a first scroll coupled to the crankshaft to receive a rotational force of the drive motor to perform an orbiting movement; a second scroll coupled to the first scroll to form a first compression unit and a second compression unit along with the first scroll; and a vane provided in the first scroll or second scroll to be brought into contact with the other side scroll to form the second compression unit, wherein the first compression unit is carried out in a scroll compression mode and the second compression unit is carried out in a rotary compression mode.

Scroll compressor

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.

The present disclosure relates to a wear-resistant surface treating agent, a manufacturing method thereof, and a compressor using the same. According to one aspect of the present disclosure, the surface treating agent includes an organic solvent, nanodiamond powder and carbon nanotube powder dispersed in the organic solvent, and a PTFE solution mixed with the organic solvent, wherein the organic solvent is an amide-based organic solvent.

Surface treating agent for wear-resistance surface, manufacturing method thereof and compressor using the same

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 twith 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.
