Definitions

  • the present invention relates to a compressor including a compression mechanism fixed to a casing.
  • An object of the present invention is to suppress vibrations of a compressor.
  • a first aspect of the present invention provides a compressor including a casing, a motor, and a compression mechanism.
  • the casing includes a cylindrical portion having an inner diameter of a first dimension.
  • the motor includes a rotor having an outer diameter of a second dimension.
  • the compression mechanism is configured to compress a low-pressure refrigerant to generate the high-pressure refrigerant.
  • a ratio of the first dimension to the second dimension is equal to or less than 1.8.
  • the compression mechanism includes a fixing portion being in tight contact with an inner peripheral surface of the cylindrical portion at a position where the compression mechanism is disposed.
  • a third aspect of the present invention provides the compressor according to the first or second aspect, wherein an average value of distances from the cylindrical portion to the compression mechanism falls within a range from 0.00 mm or more to 0.15 mm or less in the overall circumference of the cylindrical portion.
  • This configuration brings about the small average value of the distances from the inner peripheral surface of the cylindrical portion to the fixing portion of the compression mechanism. This configuration therefore further enhances the degree of tight contact of the fixing portion with the inner peripheral surface. This configuration thus further suppresses vibrations of the compressor.
  • a fourth aspect of the present invention provides the compressor according to any one of the first to third aspects, further including four or more weld portions at which the compression mechanism is fixed to the cylindrical portion.
  • the four or more weld portions contribute to stiffness to joints between the compression mechanism and the cylindrical portion. This configuration thus further suppresses vibrations of the compressor.
  • a fifth aspect of the present invention provides the compressor according to the fourth aspect, including the weld portions the number of which is six or more.
  • This configuration shortens a difference in height from each joint between the compression mechanism and the cylindrical portion to the center of gravity of the rotor. This configuration thus further suppresses vibrations of the compressor.
  • a seventh aspect of the present invention provides the compressor according any one of the first to sixth aspects, wherein the cylindrical portion is a multi-segment expanded tube including eight or more inner diameter increased portions and eight or more inner diameter decreased portions.
  • An eighth aspect of the present invention provides a method for manufacturing a compressor.
  • the manufacturing method includes a step of preparing a cylindrical portion having an inner diameter of a first dimension, a motor including a rotor having an outer diameter of a second dimension, and a compression mechanism configured to compress a low-pressure refrigerant to generate the high-pressure refrigerant.
  • the manufacturing method also includes a step of fixing the compression mechanism to the cylindrical portion so as to bring a fixing portion of the compression mechanism into tight contact with an inner peripheral surface of the cylindrical portion.
  • a ratio of the first dimension to the second dimension is equal to or less than 1.8.
  • This method enables tight contact of the compression mechanism with the cylindrical portion. This configuration therefore enables firm fixation of the compression mechanism to the casing. This configuration thus suppresses vibrations of the compressor.
  • a ninth aspect of the present invention provides the manufacturing method according to the eighth aspect, wherein the fixing portion extends over the compression mechanism so as to occupy 80% or more of an overall circumference of the inner peripheral surface.
  • the fixing portion of the compression mechanism occupies 80% or more of the overall circumference of the inner peripheral surface of the cylindrical portion. This configuration therefore enables tight contact of the compression mechanism with the casing over a wide range. This configuration thus further suppresses vibrations of the compressor.
  • a tenth aspect of the present invention provides the manufacturing method according to the eighth or ninth aspect, wherein the fixing step includes a step of welding the compression mechanism to the cylindrical portion at four or more positions.
  • the four or more weld portions contribute to stiffness to joints between the compression mechanism and the cylindrical portion. This configuration thus further suppresses vibrations of the compressor.
  • An eleventh aspect of the present invention provides the manufacturing method according to the tenth aspect, wherein in the fixing step, an average value of distances from the fixing portion to the inner peripheral surface falls within a range from 0.00 mm or more to 0.15 mm or less in the entire fixing portion.
  • This method brings about the small average value of the distances from the fixing portion of the compression mechanism to the inner peripheral surface of the cylindrical portion. This configuration therefore further enhances the degree of tight contact of the fixing portion with the inner peripheral surface. This configuration thus further suppresses vibrations of the compressor.
  • a twelfth aspect of the present invention provides the manufacturing method according to the eighth or ninth aspect, wherein the fixing step includes: a step of increasing the first dimension by heat application to the cylindrical portion; a step of inserting the compression mechanism into the cylindrical portion; and a step of decreasing the first dimension by heat radiation from the cylindrical portion.
  • the compression mechanism is fixed by shrink fitting to the cylindrical portion.
  • This configuration therefore enables contact of the compression mechanism with the substantially overall circumference of the cylindrical portion. This configuration thus further suppresses vibrations of the compressor.
  • a thirteenth aspect of the present invention provides the manufacturing method according to the eighth or ninth aspect, wherein the fixing step includes a step of applying a strong force to the compression mechanism to insert the compressor into the cylindrical portion while elastically deforming the cylindrical portion.
  • the compression mechanism is fixed by press fitting to the cylindrical portion.
  • This configuration therefore enables contact of the compression mechanism with the substantially overall circumference of the cylindrical portion. This configuration thus further suppresses vibrations of the compressor.
