Embodiment Construction

[0048] The following combination figure 1 A first embodiment of the present invention will be described.

[0049] Such as figure 1 As shown, a screw compressor A can establish a refrigeration cycle RC of an air conditioner, a refrigerator, a freezer or other similar equipment. The screw compressor A has a discharge side refrigerant pipe Pa connected to, for example, the upper surface of its upper portion in this embodiment, and has a suction side refrigerant pipe Pb connected to, for example, its side surface. From the outlet side refrigerant pipe Pa to the suction side refrigerant pipe Pb, a condenser B, an expansion valve C acting together to a pressure reducing mechanism, and an evaporator D are sequentially connected and communicated, thereby establishing a refrigeration cycle RC .

[0050] The aforementioned screw compressor A is arranged such that its longitudinal direction, such as its central axis, is perpendicular to the horizontal plane, so it is called a vertical...

Abstract

In a helical compressor, a helical compression unit is accommodated in the case. The compression unit has a cylinder, a roller eccentrically disposed in the cylinder and a helical blade disposed between an inner surface of the cylinder and the roller for separately forming a plurality of compression chambers therebetween along an axial direction of the roller. A motor unit is accommodated in the case and is operatively connected to the helical compression unit through a rotating shaft for eccentrically rotating the roller in the cylinder through the rotating shaft. According to the rotation of the roller, compressive fluid sucked into a lower compression chamber is moved along an axial direction of the rotating shaft while being sequentially compressed. The helical compression unit and the motor unit is arranged so that the helical compression unit and the motor unit are partially overlapped to each other along the axial direction.

Description

technical field [0001] The present invention relates to a screw compressor for continuously compressing a compressible fluid, such as a refrigerant in a refrigeration cycle, and a method of assembling the screw compressor. In particular, the present invention relates to a screw compressor having an improved structure for ease of assembly, a structure for supporting a bearing, and a structure for supporting a balancer, and to a method of assembling the screw compressor. Background technique [0002] A refrigeration cycle in an air conditioner for heating / cooling a room is provided by a compressor which compresses a refrigerant. As a compressor for compressing refrigerant, a screw compressor has a compression device driven by a motor and employs a screw blade. [0003] In a conventional screw compressor with screw blades, a hermetic casing accommodates a screw compressor and a motor unit which is sequentially connected to the screw compressor through a shaft to drive the comp...
