Patent ID: 7276829

Claim:
A method of manufacturing a frame unit that is secured between a cylinder block and a stator of a compressor and is adapted to rotatably support a rotary shaft press fitted in a rotor located inside the stator, comprising: preparing a frame body having a through-opening perforated at a center thereof and a plurality of fastening holes perforated at respective corners thereof, the frame body having a plate shape to be coupled at an upper surface thereof to the cylinder block; preparing a bearing member configured to be inserted and coupled in the through-opening of the frame body to rotatably support the rotary shaft, wherein the bearing member includes a first flange formed at an upper end thereof to support a lower surface of the frame body around the through-opening, and a first insert formed at an upper side of the first flange to protrude upward from the through-opening in an inserted state in the through-opening; preparing a plurality of stator supporting poles configured to be inserted and coupled in the respective fastening holes to be supported between the frame body and the stator; and coupling the bearing member to the through-opening of the frame body by means of fixing bolts, and coupling the stator supporting poles to the respective fastening holes, wherein, in the coupling of the bearing member, the fixing bolts are fastened through the frame body around the through-opening and the first flange, and an upper end of the first insert is press fitted and caulked to the upper surface of the frame body around the through-opening.
