Abstract:
A method of assembling a helical compressor comprising the steps of:preparing a rotating shaft and a rotor;inserting one end portion of the rotating shaft into the rotor thereby integrating the rotating shaft and rotor;preparing a stator;inserting the rotor having the rotating shaft through one end portion of an inner surface portion of the stator into the inner surface portion thereof;preparing a compression unit having a cylinder, a rotating member eccentrically disposed in the cylinder and a helical blade disposed between an inner surface of the cylinder, the rotating member for separately forming a plurality of compression chambers therebetween along an axial direction of the rotating member and at least one bearing attached to one end portion of the compression unit for rotatably supporting the rotating shaft, said at least one bearing being adapted to close the one end portion thereof;inserting the compression unit through the at least one bearing and the rotating member into the one end portion of the inner surface portion of the stator so that the compression unit and the stator are partially overlapped to each other along the axial direction of the rotating shaft;preparing a case; andattaching the stator having the rotor and the compression unit to an inner surface of the case.
