Jaechan An has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9057365
    Abstract: Disclosed are a bush bearing, a fabricating method thereof and a hermetic compressor having the same. A lubricant member of the bush bearing can be adhered onto a housing or press-fitted therein so as to remarkably increase the thickness of the lubricant member, whereby the bush bearing can be more resistant to abrasion, and upon applying the same to the compressor, abrasion of a crank shaft or the bush bearing can be reduced.
    Type: Grant

  • Patent number: 9039388
    Abstract: A compressor has a rotational driver in a hermetic container, a rotational shaft coupled to the rotation driver, and a compression mechanism coupled to the rotational shaft to inhale and compress refrigerant. In addition, a first bearing fixed to the compression mechanism supports the rotational shaft, and a second bearing is separated from the first bearing on the rotational shaft. The gap between the shaft and the first bearing is set to control a gap between the shaft and the second bearing.

  • Patent number: 8858196
    Abstract: A compression device a rotor and stator in a case, a shaft coupled to the rotor, and a compressor coupled to the shaft to suction, compress, and discharge refrigerant within the case. At least one bearing is used to support the shaft, and the shaft has a diameter that is 0.114 times equal to or larger than and 0.138 times equal to or smaller than an outer diameter of the stator at at least one reference position.

  • Patent number: 8419286
    Abstract: A compressor has a rotation shaft in a hermetic container, and first and second bearings to support the shaft in the container. A tolerance between the second bearing and the rotation shaft and a tolerance between the first bearing and the rotation shaft are different, so as to cause hydrodynamic lubrication to occur at one of the first or second bearings.

  • Publication number: 20110274569
    Abstract: A hermetic compressor is provided. The hermetic compressor may include a hermetic container; a stator shrink fitted and fixed to an inner wall of the hermetic container; a rotor rotatably provided at an inner portion of the stator; a crankshaft combined with the rotor; a compression device combined with the crankshaft that draws in and compresses refrigerant and discharges the refrigerant to an inner space of the hermetic container; a bearing positioned to be separated from the compression device on the crankshaft; and a bearing support shrink fitted and fixed to an inner wall of the hermetic container that supports the bearing. An outer diameter of the stator and an outer diameter of the bearing support may be larger than an inner diameter of the hermetic container.
