Compressor apparatus and manufacturing method of the same

A compressor apparatus comprising:

• a casing;
• and
• a driver coupled to the casing and configured to rotate a rotatable shaft;
• a compression portion coupled to the rotatable shaft and configured to compress fluid;
• a plurality of drive collection channels defined at an outer circumferential surface of the driver and configured to allow fluid to pass therealong;
• a plurality of compression collection channels defined at an outer circumferential surface of the compression portion and positioned to correspond to the plurality of drive collection channels, the plurality of compression collection channels being configured to allow fluid to pass therealong;
• and
• at least one of a first fastener or a second fastener, the first fastener configured to be detachably coupled to at least one of the plurality of drive collection channels and at least one of the plurality of compression collection channels to thereby fix the driver to the compression portion, the second fastener configured to be detachably coupled to at least one of the plurality of drive collection channels or at least one of the plurality of compression collection channels to thereby fix the driver to the compression portion, wherein the driver and the compression portion that are fixed to each other by the at least one of the first fastener or the second fastener are coupled to the casing.

A method for manufacturing a compressor apparatus, wherein the apparatus includes:

• a casing;
• a driver coupled to the casing and configured to rotate a rotatable shaft;
• and
• a compression portion coupled to the rotatable shaft and disposed within the casing, the compression portion being configured to compress fluid,
• wherein the method comprises:
• assembling the compression portion with the driver outside the casing, inserting an assembly of the compression portion and the driver into the casing, and
• coupling the assembly of the compression portion and the driver to the casing,
• coupling a fastener to the compression portion and the driver, the fastener configured to restrict rotation of at least one of the compression portion or the driver, the fastener configured to restrict radial movement of the rotatable shaft or movement of at least one of the compression portion or the driver in a longitudinal direction of the rotatable shaft.
