Abstract
A structure is provided that prevents excessive force from acting on a fastening portion where a guide frame is fastened to a sealed container. A fastening position of the guide frame and sealed structure is set within a range bounded by an upper meshing circumferential inner surface of the guide frame together with an upper meshing circumferential outer surface of a compliant frame and a lower meshing circumferential inner surface of the guide frame together with a lower meshing circumferential outer surface of the compliant frame.
Claims8
A scroll compressor comprising:
- a fixed scroll and an orbiting scroll that are provided inside a sealed container and are meshed together such that a compression chamber is formed between plate shaped spiral teeth of each scroll;
- a compliant frame that supports a crankshaft in a radial direction, wherein the crankshaft supports the orbiting scroll in an axial direction while rotating the orbiting scroll;
- and
- a guide frame that is fastened to the sealed container and that supports the compliant frame in the radial direction in two or more different locations in the axial direction, in which
- the orbiting scroll is moved in the axial direction when the compliant frame slides in the axial direction relative to the guide frame, wherein
- the guide frame and the sealed container are fastened in an axial direction range corresponding to the two or more locations of the support positions between the guide frame and the compliant frame, and
- a fastening position where the guide frame is fastened to the sealed container and a fixed support position of a stator of an electric motor on the sealed container are matched to a phase position in a peripheral direction of the sealed container.
