A method for and an apparatus for assembly of rotating ring rotary compressors is disclosed. A cylinder, shaft, roller and supports are initially assembled together, fixing means being kept in a slackened position. A preliminary centering operation is then carried out for bringing the axis of the shaft into a diametral plane of the cylinder constituting a predetermined reference plane. This operation is carried out by orientation of the shaft into two angular positions spaced from each other by 180°. The shaft is then oriented relative to the cylinder, the region of maximum eccentricity of the core being brought into the said reference plane. The support and the cylinder (this latter with the interposition of the roller) are then pressed onto the shaft by a thrust exerted in the said predetermined plane. They are thus brought into and held in a position of firm mutual contact: the cylinder on the roller, the roller on the eccentric core of the shaft and the support on the shaft at the sides of the eccentric core. The shaft and the support being kept in the position of firm contact, the cylinder is then given a relative movement of a predetermined magnitude in the opposite direction from the direction of the force previously exerted. The magnitude of this movement identifies the minimum aperture which is established, in use, between the outer surface of the roller and the wall of the compression chamber.

Method for the assembly of a rotating ring rotary compressor, the compressor comprising: a cylinder with a wall defining a compression chamber having a main central axis, a rotary shaft having an eccentric core for orbiting within the compression chamber, the core having a region of maximum eccentricity relative to the shaft, the shaft being supported in its position of rotation by means of first and second supports with overall tubular structures disposed on opposite sides of the cylinder, a roller fitted around the eccentric core of the shaft, and fixing means acting between the cylinder and the first and second supports capable of being brought into a closed position to clamp the cylinder and the first and second supports in a final position of assembly, the method including the steps of: bringing together the cylinder, the shaft, the roller and the first and second supports while keeping the fixing means away from the position of closure, orienting the shaft relative to the cylinder, the region of maximum eccentricity of the eccentric core being brought into a reference plane passing through the said main central axis and having a predetermined angular position relative to the cylinder, exerting a relative force between the rotary shaft on the one hand and the cylinder and the first and second supports on the other hand oriented in the said reference plane and in the direction corresponding to the bringing of the region of maximum eccentricity of the eccentric core of the shaft closer to the portion of the wall of the cylinder facing it until the shaft is brought into firm contact with the roller and the first and second supports and the roller are brought into firm contact with the cylinder, maintaining the shaft and the first and second supports in the said position of firm contact, causing a relative movement of the cylinder with respect to the shaft of a predetermined magnitude oriented in the said reference plane and in the direction opposite the direction of the said relative force, and moving the said fixing means into the closed position. Apparatus for assembling a rotating ring rotary compressor, the compressor comprising: a cylinder with a wall defining a compression chamber having a main central axis, a rotary shaft having an eccentric core for orbiting within the compression chamber, the core having a region of maximum eccentricity relative to the shaft, the shaft being supported in its position of rotation by means of first and second supports with overall tubular structures disposed on opposite sides of the cylinder, a roller fitted around the eccentric core of the shaft, and fixing means acting between the cylinder and the first and second supports capable of being brought into a closed position to clamp the cylinder and the first and second supports in a final position of assembly, the apparatus comprising: a framework having support means for holding the axis of the shaft stationary, the shaft having been assembled together with the cylinder, the roller and the first and second supports, first thrust means mounted on the framework and able to act on the cylinder and on the first and second supports assembled with the shaft and with the roller in a reference plane passing through the said main central axis in a predetermined angular position relative to the cylinder, stop means for keeping the shaft and the first and second supports in a temporary relative fixed position, and second thrust means mounted on the framework and able to act on the cylinder in the said reference plane and in the opposite direction from the first thrust means.
